## What it is
MeloTTS is a high-quality multi-lingual text-to-speech library supporting English (multiple accents), Spanish, French, Chinese, Japanese, and Korean. It offers a Python API, CLI, and web UI, and is fast enough for CPU real-time inference.

## Use cases
- convert text to natural-sounding speech in multiple languages
- generate Chinese speech mixed with English words
- run real-time TTS inference on CPU without a GPU
- build a voice assistant or chatbot with spoken replies
- narrate articles or documents as audio in different accents
- fine-tune TTS models on a custom voice dataset

## When to choose
- you need multilingual TTS including East Asian languages
- you want fast CPU-only inference without heavy hardware
- you need a permissive MIT-licensed TTS engine you can self-host
- you want a Python API plus CLI and web UI out of the box

## When to avoid
- you need voice cloning from short reference samples
- you require languages beyond the supported set
- you need the absolute highest-fidelity studio-grade synthesis
- you want a managed cloud TTS service with SLAs
