The OpenAI Realtime API documents configurable server-based and semantic turn-detection modes; behavior depends on the selected mode and settings.
Jin Dive
The OpenAI Realtime API describes VAD as automatically chunking audio and emitting speech-start and speech-stop events. Its server_vad mode segments based on periods of silence. It exposes an activation threshold from 0 to 1, prefix_padding_ms (audio included before detected speech) and silence_duration_ms (the silence interval used to detect speech stop). Its semantic_vad mode uses a semantic classifier based on the words in the utterance to estimate whether a person has finished speaking; an eagerness setting affects how long it waits. These settings and behaviors refer to the documented Realtime API modes, not every VAD algorithm.
Real-World imuse
Using server_vad to segment audio based on periods of silence.
Using semantic_vad to estimate whether the user has finished speaking from the words they have uttered.
Adjusting threshold, prefix padding and silence duration for a supported Realtime session.
Choosing eagerness to trade faster turn segmentation against allowing more time for a user to continue speaking.

Tune turn detection for the intended conversation or transcription workflow. Check the supported model/session configuration and monitor whether users are interrupted, speech onset is clipped or transcripts are chunked too early.

Voice activity detection identifies speech start and stop regions in an audio stream. The OpenAI Realtime API documents configurable server-based and semantic turn-detection modes; behavior depends on the selected mode and settings.

How does the OpenAI Realtime API’s server_vad mode determine audio chunks?
The Realtime VAD documentation says server_vad automatically chunks audio based on periods of silence.
What does silence_duration_ms configure in server_vad?
The setting controls the silence duration used to detect a speech stop; shorter settings detect turns more quickly.
What range does the documented server_vad activation threshold use?
The Realtime VAD guide documents threshold as an activation value from 0 to 1.
How does semantic_vad estimate that a user has finished speaking?
The API guide says semantic_vad scores audio based on the probability, inferred from the words, that the user is done speaking.
