This demo will showcase updates made to the ‘robot-ready spoken dialogue system’ built on the Retico framework. Updates include new modules, logging and real-time monitoring tools, integrations with the Coppelia Sim virtual robot platfrom, integrations with a benchmark, improved documentation, and pypi environment usage.
L’apprentissage auto-supervisé (SSL) a fait ses preuves pour le traitement automatique de la parole mais est généralement très consommateur de données, de mémoire et de ressources matérielles. L’approche BEST-RQ (BERT-based Speech pre-Training with Random-projection Quantizer) est une approche SSL performante en reconnaissance automatique de la parole (RAP), plus efficiente que wav2vec 2.0. L’article original de Google qui introduit BEST-RQ manque de détails, comme le nombre d’heures de GPU/TPU utilisées pour le pré-entraînement et il n’existe pas d’implémentation open-source facile à utiliser. De plus, BEST-RQ n’a pas été évalué sur d’autres tâches que la RAP et la traduction de la parole. Dans cet article, nous décrivons notre implémentation open-source de BEST-RQ et réalisons une première étude en le comparant à wav2vec 2.0 sur quatre tâches. Nous montrons que BERT-RQ peut atteindre des performances similaires à celles de wav2vec 2.0 tout en réduisant le temps d’apprentissage d’un facteur supérieur à deux.
A common metric for evaluating Automatic Speech Recognition (ASR) is Word Error Rate (WER) which solely takes into account discrepancies at the word-level. Although useful, WER is not guaranteed to correlate well with human judgment or performance on downstream tasks that use ASR. Meaningful assessment of ASR mistakes becomes even more important in high-stake scenarios such as health-care. We propose 2 general measures to evaluate the severity of mistakes made by ASR systems, one based on sentiment analysis and another based on text embeddings. We evaluate these measures on simulated patient-doctor conversations using 5 ASR systems. Results show that these measures capture characteristics of ASR errors that WER does not. Furthermore, we train an ASR system incorporating severity and demonstrate the potential for using severity not only in the evaluation, but in the development of ASR. Advantages and limitations of this methodology are analyzed and discussed.
