Example use cases
Choosing a model by cost
“Before I start transcribing audio, can you pull up all the available Microsoft AI transcription models and show me their prices per unit so I can pick the cheapest one?”
Exploring available TTS voices
“I want to generate speech but I'm not sure which voices Microsoft AI supports — can you list all the models and the voices each one offers?”
Building an example API call
“Can you fetch the Microsoft AI audio model catalog and show me an example request for one of the speech models so I can see the format I need to use?”

Endpoint
GEThttps://microsoft-ai.mpp.tempo.xyz/v1/audio/models?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover which Microsoft AI speech or transcription models are currently available, compare their per-unit pricing, check which voices are offered, or obtain an example request before making a call to the Speech or Transcriptions endpoints. Prefer this over hardcoding model names or prices, since the catalog reflects live pricing.
Side effects
- Service unavailable returns 5xx error
- Empty or malformed response if the catalog is temporarily down
- Stale pricing if the catalog is not refreshed in real time
