Azure

Azure AI Speech — enterprise realtime + fast transcription.

All prices are the vendor’s public list price — 0% markup. Extra provider knobs pass through untouched via provider_params.

Model	Modes	List price	Diarization	Word timings
azure/fast-transcription	batch	$0.36/hr	✓	✓
azure/speech-realtime	streaming	$1/hr	—	✓
azure/conversation-transcription	streaming	$1.2/hr	✓	✓

Provider options

Reach past the unified surface with provider_params — forwarded batch → fast-transcription definition fields. Typed in the SDKs as {provider}Params interfaces (providerParams option / provider_params= kwarg).

Note

Realtime runs through the Azure Speech SDK — session knobs are gateway-managed, provider_params are not forwarded on streaming models.

Param	Type	Default	Applies to	What it does
locales	array	—	batch	Candidate locales for language identification
diarization	object	—	batch	{maxSpeakers: 2–35} — mono audio only
channels	array	—	batch	Channel indices to transcribe (≤2)
