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.
\nBiographies
\nDimitri Kanevsky started his career at Google working on speech recognition algorithms. Prior to joining Google\, Dimitr i was a Research staff member in the Speech Algorithms Department at IBM . Prior to IBM\, he worked at a number of centers for higher mathematics\, including Max Planck Institute in Germany and the Institute for Advanced Studies in Princeton. He currently holds 295 US patents and was Master Inv entor at IBM. MIT Technology Review recognized Dimitri conversational biom etrics based security patent as one of five most influential patents for 2 003. In 2012 Dimitri was honored at the White House as a Champion of Chang e for his efforts to advance access to science\, technology\, engineering\ , and math.
\nFadi Biadsy is a senior staff researc h scientist at Google NY for the past ten years. He has been exploring and leading multiple projects at Google\, including speech recognition\, spee ch conversion\, language modeling\, and semantic understanding. He receiv ed his PhD from Columbia University in 2011. At Columbia\, he researched a variety of speech and language processing projects including\, dialect an d accent recognition\, speech recognition\, charismatic speech and questio n answering. He holds a BSc and MSc in mathematics and computer science. He worked on handwriting recognition during his masters degree and he work ed as a senior software developer for five years at Dalet digital media sy stems building multimedia broadcasting systems.
