Hi y’all I’m trying to find docs on how to call the Wav2Vec model for TTS via the API.

1. The [detailed API docs on parameters](https://api-inference.huggingface.co/docs/python/html/detailed_parameters.html) don’t seem yet to have information on the format of the API request for that model
2. Trying to infer it from the demo page fails because of a CORS error in Chrome:

```auto
Access to fetch at 'https://api-audio-frontend.huggingface.co/models/facebook/wav2vec2-large-960h-lv60-self' from origin 'https://huggingface.co' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Wav2Vec2 is not yet included in the official inference-api - it should be included soon though 🙂

Ah ok thanks @patrickvonplaten – sign me up for notifications when it is! Very interested in pricing too. The STT marketplace is rapidly maturing so I’m looking for the next price-driven challenger in this space.

ASR was added to the list of parameters. You basically need to send the raw audio file.
