Der volle Inhalt der QuelleEsta tesis se llevó a cabo en el Grup en Tecnologies Mèdia de la Escuela de Ingeniería y Arquitectura la Salle. El grupo lleva una larga trayectoria dentro del campo de la síntesis de voz y cuenta con su propio sistema de síntesis por concatenación de unidades (US-TTS). El sistema permite sintetizar múltiples estilos expresivos mediante el uso de corpus específicos para cada estilo expresivo. De este modo, para realizar una síntesis agresiva, el sistema usa el corpus de este estilo, y para un estilo sensual, usa otro corpus específico para ese estilo. La presente tesis aborda el problema con un enfoque distinto proponiendo cambios en el esquema del sistema con el fin de mejorar la flexibilidad para sintetizar múltiples estilos expresivos a partir de un único corpus de estilo de habla neutro. El planteamiento seguido en esta tesis esta basado en el uso de técnicas de procesamiento de señales (DSP) para llevar a cabo modificaciones del señal de voz para que este exprese el estilo de habla deseado. Para llevar acabo las modificaciones de la señal de voz se han usado los modelos harmónico más ruido (HNM) por su flexibilidad para efectuar modificaciones de señales. La cualidad de la voz (VoQ) juega un papel importante en diferentes estilos expresivos. Por ello se exploró la síntesis expresiva basada en modificaciones de parámetros de bajo nivel de la VoQ. Durante este estudio se detectaron diferentes problemas que dieron pié a los objetivos planteados en esta tesis, entre ellos el encontrar un único parámetro con fuerte influencia en la expresividad. El parámetro seleccionado fue el esfuerzo vocal (VE) por su importante papel a la hora de expresar diferentes emociones. Las primeras pruebas se realizaron con el fin de transferir el VE entre dos realizaciones con diferente grado de VE de la misma palabra usando una metodología basada en un proceso filtrado de pre-émfasis adaptativo con coeficientes de predicción lineales (APLP). Esta primera aproximación logró transferir el nivel de VE entre dos realizaciones de la misma palabra, sin embargo el proceso presentaba limitaciones para generar niveles de esfuerzo vocal intermedios. A fin de mejorar la flexibilidad y el control del sistema para expresar diferentes niveles de VE, se planteó un nuevo modelo de VE basado en polinomios lineales. Este modelo permitió transferir el VE entre dos palabras diferentes e incluso generar nuevos niveles no presentes en el corpus usado para la síntesis. Esta flexibilidad está alineada con el objetivo general de esta tesis de permitir a un sistema US-TTS expresar múltiples estilos de habla expresivos a partir de un único corpus de estilo neutro. Además, la metodología propuesta incorpora un parámetro que permite de forma sencilla controlar el nivel de VE expresado en la voz sintetizada. Esto abre la posibilidad de controlar fácilmente el proceso de síntesis tal y como se hizo en el proyecto CreaVeu usando interfaces simples e intuitivas, también realizado dentro del grupo GTM. Esta memoria concluye con una revisión del trabajo realizado en esta tesis y con una propuesta de modificación de un esquema de US-TTS para expresar diferentes niveles de VE a partir de un único corpus neutro.
This thesis was conducted in the Grup en Tecnologies M`edia (GTM) from Escola d’Enginyeria i Arquitectura la Salle. The group has a long trajectory in the speech synthesis field and has developed their own Unit-Selection Text-To-Speech (US-TTS) which is able to convey multiple expressive styles using multiple expressive corpora, one for each expressive style. Thus, in order to convey aggressive speech, the US-TTS uses an aggressive corpus, whereas for a sensual speech style, the system uses a sensual corpus. Unlike that approach, this dissertation aims to present a new schema for enhancing the flexibility of the US-TTS system for performing multiple expressive styles using a single neutral corpus. The approach followed in this dissertation is based on applying Digital Signal Processing (DSP) techniques for carrying out speech modifications in order to synthesize the desired expressive style. For conducting the speech modifications the Harmonics plus Noise Model (HNM) was chosen for its flexibility in conducting signal modifications. Voice Quality (VoQ) has been proven to play an important role in different expressive styles. Thus, low-level VoQ acoustic parameters were explored for conveying multiple emotions. This raised several problems setting new objectives for the rest of the thesis, among them finding a single parameter with strong impact on the expressive style conveyed. Vocal Effort (VE) was selected for conducting expressive speech style modifications due to its salient role in expressive speech. The first approach working with VE was based on transferring VE between two parallel utterances based on the Adaptive Pre-emphasis Linear Prediction (APLP) technique. This approach allowed transferring VE but the model presented certain restrictions regarding its flexibility for generating new intermediate VE levels. Aiming to improve the flexibility and control of the conveyed VE, a new approach using polynomial model for modelling VE was presented. This model not only allowed transferring VE levels between two different utterances, but also allowed to generate other VE levels than those present in the speech corpus. This is aligned with the general goal of this thesis, allowing US-TTS systems to convey multiple expressive styles with a single neutral corpus. Moreover, the proposed methodology introduces a parameter for controlling the degree of VE in the synthesized speech signal. This opens new possibilities for controlling the synthesis process such as the one in the CreaVeu project using a simple and intuitive graphical interfaces, also conducted in the GTM group. The dissertation concludes with a review of the conducted work and a proposal for schema modifications within a US-TTS system for introducing the VE modification blocks designed in this dissertation.

Der volle Inhalt der QuelleFirstly, given that the performance of speaker normalization techniques degrades in the presence of noise, it is shown that reducing the effects of noise through environmental compensation, prior to speaker normalization, leads to substantial improvements in ASR performance. The speaker normalization techniques considered here were vocal tract length normalization (VTLN) and the augmented state-space acoustic decoder (MATE). Secondly, given that discriminant feature-space transformation (DFT) are known to increase class separation, it is shown that performing speaker normalization using VTLN in a discriminant feature-space leads to improvements in the performance of this technique. Classes, in our experiments, corresponded to HMM states. Thirdly, an effort was made to achieve higher class discrimination by normalizing the speech data used to estimate the discriminant feature-space transform. Normalization, in our experiments, corresponded to reducing the variability within each class through the use of environment compensation and speaker normalization. Significant ASR performance improvements were obtained when normalization was performed using environment compensation, while our results were inconclusive for the case where normalization consisted of speaker normalization. Finally, aimed at increasing its noise robustness, a simple modification of MATE is presented. This modification consisted of using, during recognition, knowledge of the distribution of warping factors selected by MATE during training.

Der volle Inhalt der QuelleThis thesis focuses on speaker voice transformation in the aim to indicate the distance of it: a spokento-whispered voice transformation to indicate a close distance and a spoken-to-shouted voicetransformation for a rather far distance. We perform at first, in-depth analysis to determine mostrelevant features in whispered voices and especially in shouted voices (much harder). The maincontribution of this part is to show the relevance of prosodic parameters in the perception of vocaleffort in a shouted voice. Then, we propose some descriptors to better characterize the prosodiccontours. For the actual transformation, we propose several new transformation rules whichimportantly control the quality of transformed voice. The results showed a very good quality oftransformed whispered voices and transformed shouted voices for relatively simple linguisticstructures (CVC, CVCV, etc.)

Der volle Inhalt der QuelleVoice Conversion (VC) aims at transforming the characteristics of a source speaker’s voice in such a way that it will be perceived as being uttered by a target speaker. The principle of VC is to define mapping functions for the conversion from one source speaker’s voice to one target speaker’s voice. The transformation functions of common State-Of-The-Art (START) VC system adapt instantaneously to the characteristics of the source voice. While recent VC systems have made considerable progress over the conversion quality of initial approaches, the quality is nevertheless not yet sufficient. Considerable improvements are required before VC techniques can be used in an professional industrial environment. The objective of this thesis is to augment the quality of Voice Conversion to facilitate its industrial applicability to a reasonable extent. The basic properties of different START algorithms for Voice Conversion are discussed on their intrinsic advantages and shortcomings. Based on experimental evaluations of one GMM-based State-Of-The-Art VC approach the conclusion is that most VC systems which rely on statistical models are, due to averaging effect of the linear regression, less appropriate to achieve a high enough similarity score to the target speaker required for industrial usage. The contributions established throughout this thesis work lie in the extended means to a) model the glottal excitation source, b) model a voice descriptor set using a novel speech system based on an extended source-filter model, and c) to further advance IRCAM’s novel VC system by combining it with the contributions of a) and b)
Bous, Frederik. „A neural voice transformation framework for modification of pitch and intensity“. Electronic Thesis or Diss., Sorbonne université, 2023. http://www.theses.fr/2023SORUS382.
Der volle Inhalt der QuelleHuman voice has been a great source of fascination and an object of research for over 100 years. During that time numerous technologies have sprouted around the voice, such as the vocoder, which provides a parametric representation of the voice, commonly used for voice transformation. From this tradition, the limitations of purely signal processing based approaches are evident: To create meaningful transformations the codependencies between different voice properties have to be understood well and modelled precisely. Modelling these correlations with heuristics obtained by empiric studies is not sufficient to create natural results. It is necessary to extract information about the voice systematically and use this information during the transformation process automatically. Recent advances in computer hardware permit this systematic analysis of data by means of machine learning. This thesis thus uses machine learning to create a neural voice transformation framework. The proposed neural voice transformation framework works in two stages: First a neural vocoder allows mapping between a raw audio and a mel-spectrogram representation of voice signals. Secondly, an auto-encoder with information bottleneck allows disentangling various voice properties from the remaining information. The auto-encoder allows changing one voice property while automatically adjusting the remaining voice properties. In the first part of this thesis, we discuss different approaches to neural vocoding and reason why the mel-spectrogram is better suited for neural voice transformations than conventional parametric vocoder spaces. In the second part we discuss the information bottleneck auto-encoder. The auto-encoder creates a latent code that is independent of its conditional input. Using the latent code the synthesizer can perform the transformation by combining the original latent code with a modified parameter curve. We transform the voice using two control parameters: the fundamental frequency and the voice level. Transformation of the fundamental frequency is an objective with a long history. Using the fundamental frequency allows us to compare our approach to existing techniques and study how the auto-encoder models the dependency on other properties in a well known environment. For the voice level, we face the problem that annotations hardly exist. Therefore, first we provide a new estimation technique for voice level in large voice databases, and subsequently use the voice level annotations to train a bottleneck auto-encoder that allows changing the voice level

The research shows, first, the limits of the use of the speech place and, later, how this use and these limits affect the political action of the left, of the social movements of the left. The character of the work is theoretical, making an extensive bibliographical review and based on Critical Theory. In the first chapter we make a historical, political and theoretical point about the subject who speaks, the political action of a subject in the many visions within the left thinking. Chapter two deals with the limit of the current sense used to the speech place, namely: a liberal emphasis of politics on individuals, these are considered as an ideological category, the speech place as an individualism obliquely. Finally, it was concluded that the contemporary identity politics, represented by the use of the speech place, shifted the axis of action from the left of the collective to the individual.
A pesquisa procurou demonstrar, inicialmente, os limites do uso do lugar de fala e, posteriormente, como esse uso e esses limites afetam a atuação política da esquerda, dos movimentos sociais de esquerda. O caráter do trabalho é teórico, fazendo uma extensa revisão bibliográfica e tendo como base a Teoria Crítica. No primeiro capitulo faz-se um apontamento histórico, político e teórico referente ao sujeito que fala, a ação política de um sujeito entendida pelas variadas visões dentro do pensamento de esquerda. O capitulo dois trata da aporia do atual sentido empregado ao lugar de fala, qual seja: uma ênfase liberal da política nos indivíduos, estes tidos como uma categoria ideológica, o lugar de fala como um individualismo por via obliqua. Por fim, conclui-se que a política identitária contemporânea, representada pelo uso do lugar de fala, deslocou o eixo de atuação da esquerda da coletividade para o indivíduo.

Der volle Inhalt der QuelleThe paper focuses on the study of advertising discourse and its component – taglines to English films. Taglines from the perspective of linguistics, translation and teaching is analyzed. The main linguistic features of movie taglines, namely lexical, syntactic and stylistic, were investigated. Through the prism of translation transformations, namely lexical and grammatical, translation of movie taglines from English to Ukrainian was distinguished. Teaching strategies involving movie taglines in higher education institutions were specified. It was found out that movie taglines are noticeable phenomenon of advertising which are an inexhaustible source for the study from the point of view of linguistics. Investigation of movie taglines from the point of view of linguistics and translation will allow to reveal the main structural elements of taglines and means by which an impact on the consciousness of the recipient is made. Theoretical foundations of the study of taglines to English films have been distinguished. Material can be used in the study of advertising and advertising texts, as well in the study of taglines.

Der volle Inhalt der QuelleOne of the concerns in the field of secure communication is the concept of information security. Today’s reality is still showing that communication between two parties over long distances has always been subject to interception. Providing secure communication has driven researchers to develop several cryptography schemes. Cryptography methods achieve security in order to make the information unintelligible to guarantee exclusive access for authenticated recipients. Cryptography consists of making the signal look garbled to unauthorized people. Thus, cryptography indicates the existence of a cryptographic communication in progress, which makes eavesdroppers suspect the existence of valuable data. They are thus incited to intercept the transmitted message and to attempt to decipher the secret information. This may be seen as weakness in cryptography schemes. In contrast to cryptography, steganography allows secret communication by camouflaging the secret signal in another signal (named the cover signal), to avoid suspicion. This quality motivated the researchers to work on this burning field to develop schemes ensuring better resistance to hostile attackers. The word steganography is derived from two Greek words: Stego (means cover) and graphy (means writing). The two combined words constitute steganography, which means covert writing, is the art of hiding written communications. Several steganography techniques were used to send message secretly during wars through the territories of enemies. The major contributions of this thesis are the following ones. We propose a new method to secure speech communication using the Discrete Wavelet Transforms (DWT) and the Fast Fourier Transform (FFT). Our method exploits first the high frequencies using a DWT, then exploits the low-pass spectral properties of the speech magnitude spectrum to hide another speech signal in the low-amplitude high-frequencies region of the cover speech signal. The proposed method allows hiding a large amount of secret information while rendering the steganalysis more complex. Comparative evaluation based on objective and subjective criteria is introduced for original speech signal, stego-signal and reconstructed secret speech signal after the hiding process. Experimental simulations on both female and male speakers revealed that our approach is capable of producing a stego speech that is indistinguishable from the cover speech. The receiver is still able to recover an intelligible copy of the secret speech message. We used an LPC10 coder to test the effect of the coding techniques on the stego-speech signals. Experimental results prove the efficiency of the used coding technique since intelligibility of the stego-speech is maintained after the encoding and decoding processes. We also advocate a new steganalysis technique to ensure the robustness of our steganography method. The proposed classifier is called Autoregressive time delay neural network (ARTDNN). The purpose of this steganalysis system is to identify the presence or not of embedded information, and does not actually attempt to extract or decode the hidden data. The low detecting rate prove the robustness of our hiding technique

Der volle Inhalt der QuellePerforming arts companies operate in a context of declining resources and changes in the rules governing the allocation of grants, in accordance with the LOLF (Organic Law relative to the Laws of Finance). Their challenge lies in finding ways to address these constraints. We aim to demonstrate that their development depends on improving the manner in which all parties cooperate, based on the artistic project and taking into account the constraints resulting from the evaluation used by the LOLF, to reveal hidden costs and to develop internal resources. This research is based on the hypothesis that improving the overall performance of organizations depends on a transformative action that operates in three interdependent areas: intervention, management tools, and the speech-Actor. Based on intervention-Research in one theatre and on a qualitative study in another, we have assisted actors in the process of change management and examined the conditions in which managerial development takes place in this type of organization. We analyse how language use in the context of Socio-Economic Intervention modifies the representations and contributes to the elaboration of a new managerial instrument. We propose the use of socio-Economic management tools, serving as a framework for analyzing the organisation, combined with the criteria of evaluation and allocation of public funding as a basis of reflexion on the process of creation and dissemination of shows, as well as a means of building a shared representation between the different actors

Bjerva, Johannes. „Genetic Algorithms in the Brill Tagger : Moving towards language independence“. Thesis, Stockholms universitet, Avdelningen för datorlingvistik, 2013. http://urn.kb.se/resolve?urn=urn:nbn:se:su:diva-90472.
Der volle Inhalt der QuelleDa Brill (1992) presenterte sin enkle regelbaserte ordklasse-tagger ble det igjen aktuelt å bruke regelbaserte system for tagging av ordklasser. Taggerens grunnlag er en algoritme som automatisk lærer seg transformasjonsregler fra et korpus. I tillegg til at taggeren yter like bra som moderne stokastiske metoder for ordklasse-tagging har Brill-taggeren den fordelen at reglene den lærer seg kan presenteres i et format som lett kan oppfattes av mennesker. Til tross for sine styrker er Brill-taggeren relativt språkavhengig ettersom den fungerer mye bedre for språk som ligner engelsk enn språk med rikere morfologi. Denne oppgaven forsøker å løse dette problemet gjennom å definere regelmaler automatisk med et søk som er optimert med Genetiske Algoritmer. Dette lar Brill GA-taggeren søke gjennom et mye større område enn den ellers kunne ha gjort etter maler som i sin tur genererer regler som er tilpasset målspråket, hvilket også har fordelen at forskere ikke trenger å definere regelmaler manuelt. Brill GA-taggeren yter signifikant bedre (p<0.001) enn Brill-taggeren på alle 9 målspråk (Kinesisk, Japansk, Tyrkisk, Slovensk, Portugisisk, Engelsk, Nederlandsk, Svensk og Islandsk), med en feilprosent som er mellom 2% og 15% lavere i alle språk.

Brill GA-taggeren får signifikant bättre träffsäkerhet (p<0.001) än Brill-taggeren på alla 9 målspråken (Kinesiska, Japanska, Turkiska, Slovenska, Portugisiska, Engelska, Nederländska, Svenska och Isländska), med en felprocent som är mellan 2% och 15% lägre för alla språk.
Dey, Ken. „The effectiveness of social media in advancing transformational change“. Thesis, Gonzaga University, 2013. http://pqdtopen.proquest.com/#viewpdf?dispub=1537849.
Der volle Inhalt der QuelleThe goal of this study is to determine the effectiveness of social media in advancing transformational change. Successfully implementing transformational change in an organization is heavily dependent on the support of key stakeholders. But engaging those stakeholders requires effective communication. Transformational efforts often fail because of the lack of credible communication or a failure to define a vision that can be easily communicated (Kotter, 2007).
Researchers say that the key to successful transformational change is embracing a communication based in the realm of conversation where there is genuine two-way dialogue that is focused on listening and probing for more information (Dobbs, 2010). Creating conversations is a key component of social media: a platform of online tools designed to connect people and easily share information (Jue, Marr & Kassotakis, 2010). Social media has the potential to achieve employee engagement, enhance productivity and increase collaboration (Ou, C. J., Davison, R. M., Zhong, X., & Liang, Y.,2010).
To determine the effectiveness of social media at driving transformational change a study of existing literature related to transformational change and social media was coupled with a qualitative and quantitative study of organizational users of social media and stakeholders of those organizations. The study employed both a questionnaire and interviews. Results showed a clear preference for the use of social media as an effective form of relationship development and effective communication, but a challenge remains on how organizations can best use social media to create and sustain the relationships required to accomplish transformational change.
Cassone, Marco. „Characteristics of transformative listening enacted by organization development practitioners“. Thesis, Pepperdine University, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=1571597.
Der volle Inhalt der QuelleThis study examined the listening behaviors of organization development (OD) practitioners that result in client transformation. Interviews conducted with eleven OD consultants with extensive experience in executive coaching pointed to engaged, focused attention as a core characteristic of their listening. OD practitioners regularly use three primary listening approaches (active, empathetic, and expansive listening) to drive insight and help clients transform their perspectives. Practitioners subsequently use two secondary listening approaches (critical and reductive listening) to anchor insight into action and help clients transform their behavior. Transformative listening describes the repeating process of inquiry that blends primary and secondary listening approaches and tends to transform client perspectives and behavior. Conversely, transactional listening describes a listening approach appropriate for the negotiation and execution of agreements in the transaction of routine business. Self-awareness and use of self foster sensitivity to client needs and practitioner agility in blending the listening approaches used in transformative listening.
Douros, Ioannis. „Towards a 3 dimensional dynamic generic speaker model to study geometry simplifications of the vocal tract using magnetic resonance imaging data“. Electronic Thesis or Diss., Université de Lorraine, 2020. http://www.theses.fr/2020LORR0115.
Der volle Inhalt der QuelleIn this thesis we used MRI (Magnetic Resonance Imaging) data of the vocal tract to study speech production. The first part consist of the study of the impact that the velum, the epiglottis and the head position has on the phonation of five french vowels. Acoustic simulations were used to compare the formants of the studied cases with the reference in order to measure their impact. For this part of the work, we used 3D static MR (Magnetic Resonance) images. As speech is usually a dynamic phenomenon, a question arose, whether it would be possible to process the 3D data in order to incorporate dynamic information of continuous speech. Therefore the second part presents some algorithms that one can use in order to enhance speech production data. Several image transformations were combined in order to generate estimations of vocal tract shapes which are more informative than the original ones. At this point, we envisaged apart from enhancing speech production data, to create a generic speaker model that could provide enhanced information not for a specific subject, but globally for speech. As a result, we devoted the third part in the investigation of an algorithm that one can use to create a spatiotemporal atlas of the vocal tract which can be used as a reference or standard speaker for speech studies as it is speaker independent. Finally, the last part of the thesis, refers to a selection of open questions of the field that are still left unanswered, some interesting directions that one can expand this thesis and some potential approaches that could help someone move forward towards these directions

Der volle Inhalt der QuelleThe human voice is a powerful tool to convey emotions. Humans hear voices on a daily basis and are able to rapidly extract relevant information to successfully interact with others. The theoretical aim of this thesis is to investigate the role of familiarity on emotional voice processing. Chapters 2 and 3 present behavioral and electrophysiological studies investigating how self- versus non self-produced voices influence the processing of emotional speech utterances. By contrasting self and other, familiarity is here assessed at a personal level. The results of Chapter 2 show a dissociation of explicit and implicit processing of the self-voice. While explicit discrimination of an emotional self-voice and other-voice was somewhat impaired, implicit self-processing prompted a self-advantage in emotion recognition and speaker discrimination. Chapter 3 reports a prioritization for the non-self voice in the processing of emotional and low-level acoustic changes, reflected in faster electrophysiological (EEG) and behavioral responses. In Chapter 4, the effect of voice familiarity on is assessed at a larger sociocultural scale by comparing speech utterances in the native and a foreign language. Taken together, this thesis highlights some ways in which the ‘otherness’ of a voice - whether a non-self speaker or a foreign language speaker - is processed with a higher priority on the one hand, but with less acoustic precision on the other hand
