Local TTS model

Inflect Nano v2

Q: Can Inflect Nano v2 run locally?

Inflect Nano v2 is listed by LocalClaw as a local TTS option. Hardware fit depends on runtime, model size and backend support.

Catalogue summary: Ultra-small English fixed-voice text-to-waveform TTS with complete downloadable weights, deterministic seeds and punctuation-aware long-text chunking. The Nano checkpoint is under 4M deployable parameters, runs several times faster than real time on CPU and has an official ONNX Runtime export for torch-free local deployment.
