Rev AI’s Language Identification API is unique in being able to automatically identify the most probable language in an audio file without requiring a list of possible language codes upfront. For application developers, this feature significantly reduces the work involved in building ASR applications, as it eliminates the need to find language markers or to supply a shortlist of language possibilities to the machine transcriber.

To illustrate this, we’ve put together a tutorial (with sample code) that integrates our Language Identification and Asynchronous Speech-to-Text APIs via a Node.js webhook. By combining the two processes of language identification and transcription, our tutorial demonstrates how application developers can create a seamless and accurate speech-to-text conversion flow for their ASR applications.

We hope you enjoy the tutorial and look forward to hearing from you if you found it useful!
