Hi @restive magnet. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information available in the knowledge sources, here are some details related to Voice Activity Detection (VAD) and related issues:

  1. Realtime API and VAD: The Realtime API uses VAD to detect the end of speech in audio input. In server VAD mode, the server runs voice activity detection over incoming audio and responds after the end of speech is detected. This mode is suitable for an always-open audio channel from the client to the server. Source (https://platform.openai.com/docs/guides/realtime#concepts)

  2. Interruptions and VAD: When the server is responding with audio, interruptions can occur. In server VAD mode, interruptions happen when the server-side VAD detects input speech again. You can also explicitly interrupt the model by sending a response.cancel message. Source (https://platform.openai.com/docs/guides/realtime#handling-interruptions)

  3. Whisper and VAD: Whisper can be used for voice activity detection. The transcribe() function in Whisper provides segment-level details, including no_speech_prob, which indicates the probability of no speech. This can be used for a basic VAD, but better results might be achieved by combining it with a more accurate VAD tool. Source (https://github.com/openai/whisper/discussions/96)

  4. Error in Committing Input Audio Buffer: In the context of server VAD, it is mentioned that you don't necessarily need to pass input_audio_buffer.commit because the AI will know when you're done talking and when it has to start talking. Source (https://community.openai.com/t/1032360)

If you need more detailed information, you might want to explore the OpenAI documentation (https://platform.openai.com/docs) for further insights.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
