## What it is
MaryTTS is an open-source, multilingual text-to-speech synthesis platform written in pure Java, operating as a client-server system. It supports multiple languages and includes toolkits for adding new languages and building unit-selection or HMM-based voices.

## Use cases
- convert text to spoken audio in a Java application
- self-host a text-to-speech server
- add speech synthesis to multiple languages
- build custom TTS voices
- embed TTS in a voice assistant or accessibility tool

## When to choose
- you need a self-hosted, open-source TTS engine
- your stack is Java/JVM-based
- you need multilingual synthesis or custom voice building

## When to avoid
- you need state-of-the-art neural TTS quality
- you want a lightweight on-device mobile TTS
- you need non-Java native integration without a server

## Facets
- artifact type: library
- maturity: maintenance
- function: tts, speech-recognition, http-server
- domain: speech-processing
- platform: jvm, cross-platform
- tags: text-to-speech, speech-synthesis, java, client-server, multilingual, voice-building, natural-language-processing, web-server
