Abstract
\nMost p eople take for granted that when they speak\, they will be heard and under stood. But for the millions who live with speech impairments caused by phy sical or neurological conditions\, trying to communicate with others can b e difficult and lead to frustration. While there have been a great number of recent advances in Automatic Speech Recognition (ASR) technologies\, th ese interfaces can be inaccessible for those with speech impairments.
\nIn this talk\, we will present Parrotron\, an end -to-end-trained speech-to-speech conversion model that maps an input spect rogram directly to another spectrogram\, without utilizing any intermediat e discrete representation. The system is also trained to emit words in add ition to a spectrogram\, in parallel. We demonstrate that this model can be trained to normalize speech from any speaker regardless of accent\, pr osody\, and background noise\, into the voice of a single canonical target speaker with a fixed accent and consistent articulation and prosody. We f urther show that this normalization model can be adapted to normalize high ly atypical speech from speakers with a variety of speech impairments (due to\, ALS\, Cerebral-Palsy\, Deafness\, Stroke\, Brain Injury\, etc.) \, resulting in significant improvements in intelligibility and naturalness\, measured via a speech recognizer and listening tests. Finally\, demonstra ting the utility of this model on other speech tasks\, we show that the sa me model architecture can be trained to perform a speech separation task.< /p>\n
Dimitri will give a brief description of some key moments in development of speech recognition algorithms that he was in volved in and their applications to YouTube closed captions\, Live Transc ribe and wearable subtitles.
\nFadi will then sp eak about the development of Parrotron.

\nLarge Language Models (LLM s) have demonstrated remarkable capabilities across various domains. Howev er\, it is still very challenging to build highly-reliable applications wi th LLMs that support specialized use cases. LLMs trained on web data often excel at capturing general language patterns\, but they could struggle to support specialized domains and personalized user needs. Moreover\, LLMs can produce errors that are deceptively plausible\, making them potentiall y dangerous for high-trust scenarios. In this talk\, I will discuss some o f our recent efforts in addressing these challenges with data-efficient tu ning methods and a novel factuality evaluation framework. Specifically\, m y talk will focus on building multilingual applications\, one crucial use case often characterized by limited tuning and evaluation data.
