What it does
Speech to Text turns WAV audio into plain text. Send either a WAV file or a public WAV URL, along with an Azure locale such as en-US, and get the transcription back in the data field.
Use /file when you already have the audio in your app, or /url when the WAV is hosted elsewhere. The request bodies are small and explicit: file or url, plus language. The response is equally simple, which makes it easy to drop into ingestion pipelines, call-center tooling, note-taking apps, or any workflow that needs audio converted to text.
This service is focused on transcription only. It does not return speaker labels, timestamps, or confidence scores in the schemas provided, so plan around a single text output.
If you need to index meetings, archive voice messages, or make spoken content searchable, Speech to Text gives you a direct path from WAV audio to text without extra parsing steps.
