AI voice in 2026: who makes what
The voice landscape, mapped fast. The brief.
In 2026 AI voice spans reasoning models, paid leaders, open-weight models and consumer apps.
The map. Four camps: OpenAI's reasoning-capable Realtime voice models; ElevenLabs and peers for polished proprietary quality; Mistral's Voxtral (and Kokoro, Chatterbox, Fish Speech) for open-weight models you run yourself; and consumer apps like Sesame.
The shift. Voice is becoming a primary interface — Apple rebuilt Siri around it, OpenAI bundled reasoning into it, startups are betting products on it.
