Speech To Text
The API is highly scalable and supports a range of audio formats. User can choose between two primary API options based on the length of the audio input and the use case:
Synchronous API
Synchronous API returns the recognized text for short audio (less than 1 minutes).
To process a speech recognition request for audio longer than 1 minutes, use Asynchronous API.
Synchronous APIAsynchronous API
Asynchronous API starts a long running audio processing operation. Use asynchronous API to transcribe audio that is longer than 1 minutes. The upper limit for asynchronous API is 300 minutes.
For shorter audio, synchronous API is faster and simpler. The upper limit for asynchronous API is 300 minutes.
