Voiceprint recognition in 2 seconds: what short-utterance verification changes
2 seconds of speech is all our voiceprint model needs to recognize your unique voice. To see what that means in practice, let's get the ruler out: "Hey, how have you been?" — 1.6 s "When is my meeting with Peter this afternoon?" — 2.8 s Notice the second one is longer than the model needs. Verification would already be done before you finish asking. That matters because longer utterances do improve accuracy — more audio, more evidence. That's why enrollment still takes 6 seco

Voiceprint, enabling authentication and personalization on the edge
Just like a fingerprint, our voice is unique to each of us. With modern machine learning and compute optimization, voiceprint recognition can now be deployed on wearable and edge devices, even under demanding power efficiency constraints. For a lot small devices, fitting a user facing camera or fingerprint sensor often doesn't make sense. However, having a microphone and listening to our voice is an effective way for the device to know us. Being able to identify the user(s) o
