Speech Recognition
Transcribes real-world speech despite noise and accents.
Research
We understand sound — and create it
We work across the field — speech recognition in noise, speaker separation, synthesis, and enhancement.
Research Areas
02 / 08
Speaker Diarization
Tells who spoke when, even through overlapping speech.
03 / 08
Acoustic Scene & Event Detection
Identifies the scene and what's happening from surrounding sound.
04 / 08
Speech Synthesis
Generates natural speech and audio from text.
05 / 08
Speech Enhancement
Removes noise and reverberation to restore clear speech.
06 / 08
Audio & Speech Coding
Compresses audio into fewer bits while preserving quality.
07 / 08
3D Audio
Recreates the direction and space of sound.
08 / 08
Climate Prediction
Forecasts climate change from time-series data.
