ChatTTS
What is ChatTTS?
ChatTTS is an open-source text-to-speech model built for dialogue. The 2Noise team trained it on over 100,000 hours of Chinese and English speech so it sounds natural in back-and-forth conversation, not just scripted narration.
What sets it apart is prosody control at a granular level. The model can layer in laughter, pauses, and interjections, and it handles multiple speakers in a single session. That makes it a fit for LLM assistants, conversational audio, and dialogue-heavy multimedia.
Developers install it via pip or clone the GitHub repo. The open-source release on Hugging Face is a 40,000-hour base model under AGPLv3+. The team positions it for research and dialogue use cases, with contact at [email protected] for roadmap questions.
Whisper API
What is Whisper API?
Whisper API is a hosted speech-to-text service built around OpenAI's Whisper Large V3 model. You send audio from podcasts, meetings, or videos and get text back through a REST endpoint that follows the same request format as OpenAI's transcription API. The product is operated by Lemonfox.ai, and the site states it is not affiliated with OpenAI.
Integration is meant to be quick. The API accepts uploaded files or remote audio URLs, can label multiple speakers in a recording, and supports transcription in more than 100 languages. English translations and text summaries are also available through related models on the platform.
Pricing runs on usage rather than fixed monthly tiers. New sign-ups get the first month free with 30 hours of transcription included, then pay $0.17 per hour of audio processed. The homepage includes curl examples showing how to pass language, speaker labels, and response format parameters.
Backend developers wiring transcription into apps are the main audience, along with teams processing recorded content at scale. If you are not building software, the site links to Transcripo for browser-based speech-to-text without writing code.
