Local TTS model

WavTTS

Q: Can WavTTS run locally?

WavTTS is listed by LocalClaw as a local TTS option. Hardware fit depends on runtime, model size and backend support.

Catalogue summary: Research-grade zero-shot TTS that generates speech directly in raw waveform space instead of mel spectrograms, codec tokens or VAE latents. High-fidelity EN/ZH voice cloning direction, but the official 16 kHz checkpoint is large and best for CUDA GPU setups.
