ChatTTS vs HitPaw VoicePea (formerly HitPaw Voice Changer)

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.

HitPaw VoicePea turns your microphone into 200+ live AI voices for games, streams, and calls on PC and Mac. Pick a character voice, map keybinds, trigger a built-in meme soundboard, and route the output through Discord, Zoom, Microsoft Teams, Twitch, YouTube, or Kick with ultra-low latency.

Most voice changers add noticeable delay that breaks game comms. HitPaw VoicePea targets real-time use with noise reduction, virtual audio routing, and one-click voice swaps mid-stream. The same app also covers AI cover songs, text-to-speech voiceovers, audio and video file voice replacement in 50+ formats, royalty-free AI music generation, and AI audio cleanup.

Gamers, streamers, VTubers, and remote workers who want privacy or character voices during live sessions are the core users. A free tier covers basic real-time voice changing, while paid plans on the HitPaw store start at $15.95 per month for the full VoicePea desktop app.
