Local TTS model

Sopro V2 Turbo

Q: Can Sopro V2 Turbo run locally?

Sopro V2 Turbo is listed by LocalClaw as a local TTS option. Hardware fit depends on runtime, model size and backend support.

Catalogue summary: Apache-licensed 120M voice-cloning TTS model for private, low-latency speech generation. The official Sopro package runs locally on CPU, MPS or CUDA, supports streaming with about 300 ms time-to-first-audio on an M3 CPU, and also exposes an ONNX browser path for English, European Portuguese, French and German.
