The advent of Next Generation DNA Sequencing technologies has revolutionized the field of personalized genomics through their resolution and low cost. However, these new technologies are associated with a relatively high error rate, which varies between 0.1% and 1% for second-generation sequencers. This value is problematic when searching for low allelic ratio variants, as observed in the case of heterogeneous tumors. Indeed, such error rate can lead to thousands of false positives. Each region of the studied DNA must therefore be sequenced several times, and the variants are then filtered according to criteria based on their depth. Despite these filters, the number of errors remains significant, showing the limit of conventional approaches and indicating that some sequencing errors are not random.In the context of this thesis, we have developed an exact algorithm for over-represented degenerate DNA motifs discovery on the upstream of non-random sequencing errors and thus potentially linked to their appearance. This algorithm was implemented in a software called DiNAMO, which was tested on sequencing data from IonTorrent and Illumina technologies.The experimental results revealed several motifs, specific to each of these two technologies. We then showed that taking these motifs into account in the analysis reduced significantly the false-positive rate. DiNAMO can therefore be used downstream of each analysis, as an additional filter to improve the identification of variants, especially, variants with low allelic ratio

Usual methods to design automatic speech recognition systems require speech datasets with high quality transcriptions. These datasets are composed of the acoustic signals uttered by speakers and the corresponding word-level transcripts representing what is being said. It takes several thousand hours of transcribed speech to build a good speech recognition model. The dataset must include a variety of speakers recorded in different situations in order to cover the wide variability of speech and language. To create such a system, human annotators are asked to listen to audio tracks and to write down the corresponding text. This process is costly and can lead to errors. What is beeing said in realistic settings is indeed not always easy to understand. Poorly transcribed signals cause a drop of performance of the acoustic model. To improve the quality of the transcripts, the same utterances may be transcribed by several people, but this leads to an even more expensive process.This thesis takes the opposite view. We design algorithms which can exploit datasets with “noisy” transcriptions i.e., which contain errors. The main goal of this thesis is to reduce the costs of building an automatic speech recognition system by limiting the performance drop induced by these errors.We first introduce the Lead2Gold algorithm. Lead2Gold is based on a cost function that is tolerant to datasets with noisy transcriptions. We model transcription errors at the letter level with a noise model. For each transcript in the dataset, the algorithm searches for a set of likely better transcripts relying on a beam search in a graph. This technique is usually not used to design cost functions. We show that it is possible to explicitly add new elements (here a noise model) to design complex cost functions.We then express the Lead2Gold loss in the wFST formalism. wFSTs are graphs whose edges are weighted and represent symbols. To build flexible cost functions we can compose several graphs. With our proposal, it becomes easier to add new elements, such as a lexicon, to better characterize good transcriptions. We show that using wFSTs is a good alternative to using Lead2Gold's explicit beam search. The modular formulation allows us to design a new variety of cost functions that model transcription errors.Finally, we conduct a data collection experiment in real conditions. We observe different types of annotator profiles. Annotators do not have the same perception of acoustic signals and hence can produce different types of errors. The explicit goal of this experiment is to collect transcripts with errors and to prove the usefulness of modeling these errors

My thesis concerns a study of continuous word representations applied to the automatic detection of speech recognition errors. Our study focuses on the use of a neural approach to improve ASR errors detection, using word embeddings. The exploitation of continuous word representations is motivated by the fact that ASR error detection consists on locating the possible linguistic or acoustic incongruities in automatic transcriptions. The aim is therefore to find the appropriate word representation which makes it possible to capture pertinent information in order to be able to detect these anomalies. Our contribution in this thesis concerns several initiatives. First, we start with a preliminary study in which we propose a neural architecture able to integrate different types of features, including word embeddings. Second, we propose a deep study of continuous word representations. This study focuses on the evaluation of different types of linguistic word embeddings and their combination in order to take advantage of their complementarities. On the other hand, it focuses on acoustic word embeddings. Then, we present a study on the analysis of classification errors, with the aim of perceiving the errors that are difficult to detect. Perspectives for improving the performance of our system are also proposed, by modeling the errors at the sentence level. Finally, we exploit the linguistic and acoustic embeddings as well as the information provided by our ASR error detection system in several downstream applications
