## About

## 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.
