Current Role

Dr. Quan Wang is currently working on Gemini Audio in the GenAI department of Google DeepMind.

Prior to GenAI, Dr. Quan Wang led the Hotword Modeling team and the Speaker, Voice & Language team at Google DeepMind. The teams delivered a diverse set of server-side and on-device speech models to Google’s product ecosystem, including “Hey Google” spoken keyword spotting, voice match, language recognition, spoofed speech detection, speech enhancement, speaker diarization, and multilingual speech recognition. The server-side models power numerous speech features in Google Search, YouTube, Google Cloud, and Google Assistant, used by billions. The on-device models are deployed on billions of Android phones, tablets, Chromebooks, cars, and wearables across the globe.
