Tts Server Android
tts-server-android is a system-level text-to-speech service for Android that routes synthesis requests to external cloud APIs or local engines. It functions as an HTTP speech synthesis gateway, converting system speech requests into customizable HTTP requests for remote cloud services.
The project includes a narrative dialogue parser that uses quotation marks to differentiate between narration and dialogue, allowing for different reading styles. It also features a voice manager and synthesis interface to implement text replacement rules and automatic retries to improve voice output accuracy.
The service covers broader capabilities including local engine management for offline voice functionality, cloud API routing, and pronunciation customization through rule-based text preprocessing.
Features
