Why Local TTS Now
Two things changed: open source TTS crossed the 'good enough' line, and privacy-conscious users stopped wanting every text sent to a cloud API. In 2026 a local engine on a laptop sounds close to cloud quality for most use cases - and costs nothing beyond electricity.
The Engines
Kokoro (8,406 stars, 2026-08-14) - the 2025-26 breakout: a compact model (82M params) that sounds remarkably natural, especially in English. Fast on CPU, easy to install, and the quality/price ratio (free) is the best in the local world. The reference for 'local is enough'.
Piper (11,278 stars) - the lightweight veteran: fast, tiny, runs on Raspberry Pi class hardware. Less natural than Kokoro but instant and reliable. Perfect for home automation, notifications, accessibility.
Coqui TTS (XTTS) (the classic, 45,883 stars history) - the full-featured engine: voice cloning, multilingual, fine-tuning. Heavier to set up; the choice when you need cloned voices offline.
ChatTTS - the conversational TTS: designed for dialogue, with laughter and pauses. Great for video dubbing and chatbots; more setup work.
Bark (Meta's text-to-audio) - beyond speech: music, sound effects, and expressive speech from text. Overkill for plain TTS but unmatched for creative audio.
The 10-Minute Setup (Kokoro)
- pip install kokoro (or use the bundled installer).
- Download the voice model (a few hundred MB).
- Run: text in, WAV out, on CPU.
- Wire it into your app: notification reader, audiobook pipeline, accessibility.
