The model transcribes 60 languages and delivers its first partial results in just over 100 milliseconds. Microsoft says this lets voice agents respond while someone is still mid-sentence. Through the end of the year, an hour of audio costs $0.54 at the introductory price. Microsoft also released two new text-to-speech models. [MAI-Voice-2.1](https://learn.microsoft.com/en-us/azure/ai-services/speech-service/mai-voices?context=%2Fazure%2Ffoundry%2Fcontext%2Fcontext&tabs=mai-voice-2-1-flash&pivots=ai-foundry) is designed to speak 23 languages in the same voice, with a native accent in each one. According to Microsoft, the MAI-Voice-2.1-Flash variant hits a latency of 150 milliseconds and costs $15 per million characters instead of $22. Both voice models can clone a voice from just a few seconds of reference audio, and built-in safeguards are meant to prevent misuse. The models are available through Microsoft Foundry and the [MAI Playground](http://playground.microsoft.ai/), among other platforms, and the two voice models are also on [OpenRouter](https://aka.ms/mai-openrouter). In one test, about half of the 4,000 participants thought the voices belonged to a real person. ``` AI News Without the Hype – Curated by Humans Subscribe to THE DECODER for ad-free reading, a weekly AI newsletter, our exclusive "AI Radar" frontier report six times a year, full archive access, and access to our comment section.
