Overview

The Language Identification API provides additional speech insights by identifying the spoken language in a given transcript.

API endpoint

The base URL for this version of the API is https://api.rev.ai/languageid/v1/. All endpoints described in this documentation are relative to this base URL.

Authentication

Clients must authenticate by including their Rev AI access token as a query parameter in their requests. If the access token is invalid or the query parameter is not present, a 401 error code will be returned.

Confidence scores

The confidence scores in a result represent how confident our model is that the given language is the language spoken in the submitted audio. This score is always a numeric value in the range [0, 1].
