How Google Meet’s Noise Cancellation Works
Emil Protalinski on venturebeat.com:
Serge Lachapelle, G Suite director of product management, has been working on video conferencing for 25 years, 13 of those at Google. As most of the company shifted to working from home, Lachapelle’s team got the go-ahead to deploy the denoiser in Google Meet meetings. We discussed how the project started, how his team built noise cancellation, the data required, the AI model, how the denoiser works, what noise it cancels out and what it doesn’t, privacy, and user experience considerations (there is no visual indication that the denoiser is on).
Long interview about the feature. I’ll try is as soon as available.
Crucially, Google Meet’s noise cancellation is being rolled out for all languages. That might seem obvious at first, but Lachapelle said the team discovered it was “super important” to test the system on multiple languages.
“When we speak English, there’s a certain range of voice we use,” Lachapelle said. “There’s a certain way of delivering the consonants and the vowels compared to other languages. So those are big considerations. We did a lot of validation across different languages. We tested this a lot.”
