OuteTTS
Tiny open text-to-speech with zero-shot voice cloning.
About
OuteTTS is a compact open-source TTS system from OuteAI that turns text into speech with zero-shot voice cloning from a short reference clip. The v1.0 line pairs a 0.6B model on a Qwen3-0.6B base (Apache-2.0) with a 1B variant on Llama-3.2-1B, covering English, Japanese, Korean, Chinese, French, and German.
It is built to run locally — pip install, pick a model, and generate — which makes it a practical pick for hobby projects and on-device voice features. The tradeoff for its size is voice quality and expressiveness that trail larger systems like Zonos or IndexTTS2.

Use cases
Trust score — 6/10
Scored 6/10 (metrics tier, metrics-v1). Evidence: Small community project; GitHub/HF presence but thin independent coverage; v1.0 exact release date not pinned in sources read — releasedAt left null; Manual review: honest local-first TTS; trails larger systems on quality. License: v1.0 on Qwen3-0.6B base is Apache-2.0; v0.3 500M was CC-BY-SA-4.0, 1B CC-BY-NC-SA-4.0 — check the variant you use.
