VoiceAgentInputTranscriptionModel type

The input-audio transcription model identifier. This is a model name, not a Foundry deployment name. Mirrors the transcription models supported by the managed voice backend, covering the OpenAI Realtime transcription models plus the Azure and MAI models. azure-speech-streaming is supported for cascaded text-model conversations only (not realtime speech-to-speech models), requires a nonempty language such as en-US (comma-separated locales are supported), and supports custom_speech, phrase_list, and profanity_filter. Additional values may be added over time.
