MeloTTS
MIT-licensed multilingual TTS that runs in real time on CPU.
About
MeloTTS is a multilingual text-to-speech library from MyShell.ai covering English (several accents), Spanish, French, Chinese, Japanese, and Korean. It is genuinely MIT-licensed for commercial and non-commercial use, runs fast enough for CPU real-time inference, and supports training on custom datasets. The Chinese voice handles mixed Chinese-English text. Quality is a step below the newest neural TTS systems, and some language frontends pull in extra dependencies, but for a permissively licensed workhorse it is hard to beat.

Benchmarks
Authors claim CPU real-time inference; no standardized benchmark figures published.
Provider-reported unless a source says otherwise. Benchmarks are marketing-adjacent by nature — treat them as directional.
