buildConfirmed7 publishers xAI's Grok Voice 3.0 tops Artificial Analysis' speech-to-speech index at $0.08 a minute, the same price as Grok Voice 2.0. The cost case is a per-task comparison with two rivals, and runtimewire reports text input is billed separately.

buildOne report1 publisher Microsoft's official LiveKit plugin streams agent audio to its preview MAI transcription model
Microsoft's official plugin lets LiveKit Agents stream live audio to MAI-Transcribe-2-Streaming, a realtime model covering roughly 60 languages. The service is still a public preview that Microsoft does not recommend for production.

LiveKit Agents now speaks in Microsoft's MAI voices, including MAI-Voice-2-Flash, through an official plugin that covers text-to-speech only. Teams no longer write their own adapter, but every deployment still needs an Azure Speech key and region.

buildOne report1 publisher A second check on a 300ms silence cutoff cut voice-agent interruptions from 22% to 3.1%
Preterview's developer cut mid-answer interruptions from 22% to 3.1% by confirming Deepgram's 300ms silence cutoff with a completeness check. The fix added 140ms at the median, against about 900ms for a longer timer, and threw away one drafted reply in five.
