ChatTTS vs Suno

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.

Suno turns a text prompt into a complete, original song with vocals, lyrics, and full production in under a minute. Millions of people use it to make music for the first time or shape ideas they already have. It runs in the browser and on iOS and Android, where it ranks among the top 10 music apps.

Most generators stop at short instrumental loops. Suno builds full tracks across genres from a mood, theme, or your own lyrics. You can regenerate, extend, remix, and refine with pro editing tools, stem separation, and controls like Voices, Inspo, vocal gender, and style sliders.

Suno Studio adds a web-based generative audio workstation that blends traditional DAW workflows with music generation. Paid subscribers get commercial rights to new songs, can export up to 12 time-aligned WAV stems for Ableton or Logic, and unlock advanced models like v5.5 with personas and custom voice tuning.

The company is headquartered in Cambridge, MA with offices in New York and Los Angeles. Suno has been featured in Rolling Stone, Billboard, Wired, and Variety, and is used by everyone from first-time creators to chart-topping producers.
