Simple REST API for speech-to-text transcription of short audio files (up to 60 seconds). No SDK required - just HTTP requests. 1. Azure subscription - Create one free 2. Speech resource - Create in Azure Portal 3. Get credentials - After deployment, go to resource > Keys and Endpoint 🔑 Two rules apply to every code sample below: 1. Two auth modes are supported. Use a subscription key (Ocp-Apim-Subscription-Key header) for quick access, or a Microsoft Entra token (including one acquired with DefaultAzureCredential) via the Authorization request header (see "Option 2" below). Never hardcode credentials in source. 2. Use context managers for files and HTTP resources so file handles and network connections are released deterministically: - Sync: with open(...) as f: and (when reusing connections) with requests.Session() as session: - Async: async with aiohttp.ClientSession() as session: Snippets may abbreviate this setup, but production code should always follow both rules. | Format | Codec | Sample Rate | Notes | |--------|-------|-------------|-------| | WAV | PCM | 16 kHz, mono | Recommended | | OGG | OPUS | 16 kHz, mono | Smaller file size | Limitations: Maximum 60 seconds of aud
