Bakgrunnur

Um OpenAI

Stofnað 2015 · San Francisco, California, USA

OpenAI was founded in December 2015 by Sam Altman, Elon Musk, Greg Brockman, Ilya Sutskever, Wojciech Zaremba and John Schulman as a non-profit AI research lab. It restructured into the capped-profit OpenAI LP in 2019 and has since received over $13B from Microsoft plus billions more from Thrive Capital, Sequoia, Khosla and SoftBank, at a 2024 valuation north of $157B and a planned 2025 round reportedly at $500B. The audio research line at OpenAI includes Jukebox (2020), Whisper (2022) and the TTS-1 family released in November 2023 alongside the ChatGPT voice feature. TTS-1 powers ChatGPT Voice Mode, the OpenAI API audio endpoint and the Realtime API used in voice agents.

Arkitektúr

Proprietary Transformer text-to-speech with neural codec

OpenAI TTS-1 is the standard-quality variant of OpenAI's text-to-speech model family, optimised for real-time streaming inside ChatGPT Voice and the Realtime API. It is a Transformer-based model that predicts neural-codec audio tokens conditioned on text and a fixed set of stock voices (alloy, echo, fable, onyx, nova, shimmer) that OpenAI recorded with professional voice talent. There is no voice cloning. The model supports six output formats (MP3, Opus, AAC, FLAC, WAV, PCM) and outputs at 24 kHz. TTS-1 is tuned for low latency and starts streaming audio within a few hundred milliseconds, making it suitable for live conversational agents, while the HD sibling trades latency for fidelity. Text input is capped at 4,096 characters per request. OpenAI has not published a technical paper but the system architecturally resembles published neural-codec TTS such as VALL-E.
