NeuTTS is a collection of open-source, on-device text-to-speech models built on small LLM backbones, with instant voice cloning from as little as 3 seconds of audio. Models ship in GGUF quantizations for running locally on phones, laptops, and Raspberry Pis.

Use cases

• run text-to-speech offline on my own device
• clone a voice from a short audio sample
• build an embedded voice assistant or talking toy
• generate speech locally without cloud APIs for privacy compliance
• run a small TTS model on a Raspberry Pi
• synthesize multilingual speech in French, German, or Spanish

When to choose

• you need private, on-device speech synthesis without sending audio to a cloud API
• you want instant voice cloning with minimal reference audio
• you target resource-constrained hardware like phones or Raspberry Pis
• you need GGUF quantized models for efficient local inference

When to avoid

• you need the highest possible TTS quality regardless of model size
• you require a fully permissive license - the license is non-standard
• you need extensive language coverage beyond the supported languages
• you prefer managed cloud TTS services with SLAs
