The prerequisites to set-up and use the STT API are:

WWS Port


Speech Recognition Type

Continuous Speech Recognition

No. of Channel


Time Limit

The requests are limited to audio data of 180 seconds (3 minutes) or less in duration.

Note: The default audio length duration is set for 15 seconds.

Supporting Languages

The solution will understand regional accents, bi-lingual nature of Indians, and is dialect-agnostic. it will transcribe the audio from widely spoken Indian languages:
