Is Avencera more accurate than Microsoft Azure?

Microsoft Azure is more accurate on the one published result that covers both, so the choice comes down to price against accuracy. Azure Speech, July 2026 scores 5.02% on the Open ASR Leaderboard, English, against 6.02% for Parakeet v2.

Can Azure transcribe a long recording with speaker labels?

Up to 240 minutes per file. Longer recordings have to be split first, which can renumber speakers between parts. Avencera takes up to 24 hours in one request.

How do I switch from Microsoft Azure to Avencera?

Avencera uses OpenAI’s transcription API format, so any OpenAI SDK works. Send the same audio files you send Microsoft Azure, and map its response fields to the OpenAI-style transcript.
