Pick Microsoft MAI-Voice-1 if...

  • Easier to use (6 vs 5)

Microsoft shops already on Azure who want a TTS option without an OpenAI dependency. Also good for any high-volume TTS workflow (audiobook batch generation, voicemail systems, IVR, bulk narration) where the 60x-faster-than-realtime speed beats ElevenLabs v3's slightly more expressive output.
