NeuTTS Nano Multilingual Collection: 120M Params on-device TTS in German, French, and Spanish

Run high-quality, multilingual text-to-speech locally on your phone or laptop.

Deep Dive

Neuphonic has released three new language-specific NeuTTS Nano models for German, French, and Spanish. Each model contains 120 million active parameters, matching the English version. They enable real-time inference on CPU using llama.cpp, support zero-shot voice cloning from just 3 seconds of audio, and run fully locally on devices like phones, laptops, and Raspberry Pi. The models use a compact LM backbone with the open-source NeuCodec audio codec.

Why It Matters

This brings professional-grade, private, and multilingual voice synthesis directly to consumer devices, bypassing cloud services.
