GPT-Live (ChatGPT Voice)
OpenAI's full-duplex voice models (launched in ChatGPT 2026-07-08) -- listens and speaks at the same time, backchannels naturally, and delegates hard questions to a backend model while keeping the conversation going. **GPT-Live-1 reached the API on 2026-09-10 at $0.05 per minute** for the voice layer, with telephony support, keyword biasing, delegation to any backend model (GPT-6 Astra, Luna, or a third-party model) and a wider voice set. In ChatGPT: GPT-Live-1 for paid tiers, GPT-Live-1 mini for Free. **Five days after the API launch, Google priced Gemini 3.8 Live at $0.005/min audio in and $0.018/min audio out (2026-09-15)** -- a fraction of GPT-Live-1's $0.05/min voice layer, though each stack bills backend or text tokens on top
ElevenLabs
Best-in-class AI voice generation -- 11.ai (MCP-based voice assistant), Eleven v3 expressive speech, ElevenMusic and ElevenAgents. **On 2026-09-10 ElevenLabs signed a multi-year licensing and product deal with Universal Music Group** -- its first major-label agreement -- to build a fan remix/mashup platform on licensed music. **ElevenLabs CLI v1 (2026-08-24)** exposes the entire API in the terminal with agents-as-code. $500M+ ARR (May 2026); $500M raise at $11B valuation (Feb 2026)
Descript
Edit audio and video by editing text -- the 'Google Docs of media editing' actually lives up to the hype
Grok Speech (STT + TTS APIs)
xAI's standalone voice APIs. **Grok Voice Transcribe 2.0 shipped 2026-09-18** -- xAI calls it twice as accurate as 1.0 at the same $0.10/hr batch and $0.20/hr streaming, ranks it first for accuracy among 32 streaming models on Artificial Analysis, and has already made it the default STT model; **1.0 is being retired in the coming weeks, so pin grok-voice-transcribe-1.0 if you need it**. **PRICE CORRECTION: text-to-speech is $15.00 per 1M characters on xAI's live rate card (verified 2026-09-21), not the $4.20 this page carried since April.** Speech-to-speech agent $0.08/min, 26 flagship voices, ~1-minute voice cloning, no-code Voice Agent Builder
Cohere Transcribe
Cohere's first audio model -- launched 2026-03-26 under Apache 2.0, 2B parameters, #1 on Hugging Face Open ASR Leaderboard (5.42 avg WER), 14 enterprise-critical languages. Free API with rate limits; Model Vault for production
Microsoft MAI-Voice-2
Microsoft's in-house expressive TTS model -- MAI-Voice-2 launched 2026-06-02 at Build: 15 languages (up from English-only), granular emotion-tag control, zero-shot voice cloning from a 5-60s clip, and preferred over MAI-Voice-1 72% of the time. In speaker-similarity tests its speech is 'indistinguishable' from real recordings. On Azure Foundry + integrated into VS Code and Dynamics 365 Contact Center; lower-cost MAI-Voice-2-Flash coming. Original MAI-Voice-1 shipped 2026-04-02
