Recent Advances in End-to-End Speech Recognition

video/mp4This talk explains recent advances in end-to-end automatic speech recognition (ASR) at NTT. First, I will give an overview of NTT speech technologies and open-source toolkit ESPnet. Then, I will introduce our proposed semi-supervised end-to-end ASR method (ICASSP19 https://ieeexplore.ieee.org/abstract/document/8682890). In this paper, we introduce speech and text autoencoders that share encoders and decoders with an automatic speech recognition (ASR) model to improve ASR performance with large speech only and text only training datasets. To build the speech and text autoencoders, we leverage state-of-the-art ASR and text-to-speech (TTS) encoder-decoder architectures. These autoencoders learn features from speech only and text only datasets by switching the encoders and decoders used in the ASR and TTS models. Simultaneously, they aim to encode features to be compatible with ASR and TTS models by a multi-task loss. Additionally, we anticipate that TTS joint training can also improve ASR performance because both ASR and TTS models learn transformations between speech and text. The experimental result we obtained with our semi-supervised end-to-end ASR/TTS training revealed reductions from a model initially trained with a small paired subset of the LibriSpeech corpus in the character error rate from 10.4% to 8.4% and word error rate from 20.6% to 18.0% by retraining the model with a large unpaired subset of the corpus.講演者所属: NTT Communication Science Laboratories 講演日: 2019年11月13日 講演場所: 情報科学棟大講義室L1vide

An Analysis of Structure of Free Jets by Flow Visualization

application/pdfStructures of the free jets from small nozzles are studied by flow visualization. Tests are carried out with He, air, CF₄, CCl₂F₂ and CCl₄ seeded with I₂ which radiates fluorescence by illumination of an Ar-ion laser beam. Entire flow field of the jets is visualized by scanning of the laser beam along the jet axis. Positions of the Mach-disc, barrel shock and jet boundaries are determined from the photographs. Local velocity and density distributions are measured by the micro-densitometric study of the quenching of the fluorescence.departmental bulletin pape

The presence of LRV2-<i>Lae</i> leads to TLR3-dependent production of pro-inflammatory cytokines by <i>in vitro</i> infected macrophages.

<p>C57BL/6 (in black) and TLR3 knock-out (in grey) murine bone marrow derived macrophages were infected by <i>Leishmania</i> promastigotes (parasite/macrophage ratio 10∶1), and the level of IL-6 (<b>A</b>) and TNF-α (<b>B</b>) in culture supernatants was measured by ELISA 24 hours post-infection. Non inf.: non-infected macrophages. The cut-off line was calculated as 3 standard deviations (SD) above the mean absorbance of the uninfected macrophage control. Average values presented were obtained from two independent experiments performed in duplicates.</p

<i>L. aethiopica</i> LRV genomes analysis in comparison to LRV1 and LRV2.

<p>The three <i>L. aethiopica</i> LRV genome sequences (303, 327 and L494) were aligned and compared to each other (LRV-<i>Lae</i>), as well as to LRV2 from <i>L. major</i> ASKH and LRV1 from <i>L. guyanensis</i> CUMC1 and M4147 using LALIGN software from Expasy. Total nucleotide (Genome column) and deduced amino acid sequences of the capsid protein (CP column) and RNA-dependent RNA polymerase (RdRp column) were analyzed. The percentage of identical residues is indicated. Average percentage of identity for each LRV group was also included and highlighted in bold (‘average’ lines).</p

<i>Leishmania aethiopica</i> lines used in this work.

<p>LRV status was determined by a dot blot assay (dsRNA detection) for the eight fresh isolates, and by PCR using universal LRV-specific primers on cDNA obtained from the three cryobank lines (see <a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0002836#s2" target="_blank">Methods</a>). dsRNA was weakly detected in the <i>Lae</i> 315 strain (+). The four isolates selected for further analysis are highlighted in bold, as well as the L494 strain that was used for LRV sequencing. Parasites were isolated from patients suffering from cutaneous (CL) or diffuse cutaneous leishmaniasis (DCL) as indicated in the “pathology” column.</p

<p>Promastigotes were fixed with formaldehyde and spread on poly-lysine coated slides before visualization of viral dsRNA with the J2 antibody (standardized exposure time in all images: 200 ms). Scale bars: 10 µm.</p
