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

Описание и применение

Создана система TTS с 322 голосами на 142 языках, включая 10 индийских, с низкой задержкой и доступной ценой.

Задача

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

Результат

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