Struct AudioTranscription 

pub struct AudioTranscription {
    pub language: Option<String>,
    pub model: Option<String>,
    pub prompt: Option<String>,
    pub delay: Option<AudioTranscriptionDelay>,
}

Fields

language: Option<String>

The language of the input audio. Supplying the input language in ISO-639-1 (e.g. en) format will improve accuracy and latency.

model: Option<String>

The model to use for transcription. Current options are whisper-1, gpt-4o-mini-transcribe, gpt-4o-mini-transcribe-2025-12-15, gpt-4o-transcribe, gpt-4o-transcribe-diarize, and gpt-realtime-whisper. Use gpt-4o-transcribe-diarize when you need diarization with speaker labels.

prompt: Option<String>

An optional text to guide the model’s style or continue a previous audio segment. For whisper-1, the prompt is a list of keywords. For gpt-4o-transcribe models (excluding gpt-4o-transcribe-diarize), the prompt is a free text string, for example “expect words related to technology”. Prompt is not supported with gpt-realtime-whisper in GA Realtime sessions.

delay: Option<AudioTranscriptionDelay>

Controls how long the model waits before emitting transcription text. Higher values can improve transcription accuracy at the cost of latency. Only supported with gpt-realtime-whisper in GA Realtime sessions.
