We show how to connect to the Azure Speech endpoint via REST using JSON, send Base64-encoded audio or upload large files to Azure storage for faster access, authenticate with API keys or Entra identities, and use the SpeechConfig and SpeechRecognizer classes with recognize_once_async to get transcriptions with per-word time offsets.
