AI Audio Language Detection API

Hosted on ApyHub

What it does

Audio Language Detector identifies the spoken language in an audio file and returns a locale code with a confidence score. Send a WAV, MP3, or another supported audio file, or point the API at a publicly accessible audio URL.

Use it when you need to route recordings to the right transcription pipeline, pre-sort call-center audio by language, or add language-aware logic to voice apps before transcription starts. The API is useful when you only need a fast language check and not a full transcript.

The /file endpoint accepts a binary file upload in the request body. The /url endpoint accepts a public url to the audio asset. Both endpoints return data.azure.language as a locale such as en-US, along with data.azure.confidence as a score from 0.0 to 1.0.

Audio Language Detector is a good fit when you want a lightweight classification step for audio ingestion, moderation, or localization workflows without building your own model pipeline.
