No description
Introduce configurable segment preloading depth, sentence lookahead, and TTS segment max block length for both PDF and EPUB readers. Add new settings to user preferences, config context, and document settings UI. Refactor TTS segment splitting logic to support per-user max block length and propagate these options through PDF/EPUB adapters and TTS segment generation. Update API, manifest pagination, and segment deduplication for improved performance and correctness. Add tests for new NLP options and manifest logic. BREAKING CHANGE: TTS segment splitting and manifest APIs now require max block length and preloading parameters; user config schema updated. |
