Building a 322-Voice Multilingual TTS Engine: Architecture & Challenges

说明与用途

构建了一个拥有322个声音、覆盖142种语言的TTS引擎，支持低延迟和低成本定价。

问题

Commercial TTS systems focus on English/major European languages, charge high per-character fees, and lack authentic regional pronunciation, limiting multilingual voice accessibility.

结果

The engine supports 322 voices in 142 languages, offers authentic regional pronunciation, and provides a low-cost, low-latency solution for multilingual voice output.

工作流

• 2. Created phoneme dictionaries for 142 languages.
• 3. Implemented 10 ms streaming latency using WebAudio API.
• 4. Integrated dynamic SSML generation via self‑healing code engine.
• 5. Deployed engine to LuxurAI Cowork desktop automation agent.
• 6. Released beta and solicited feedback from linguists and audio engineers.
