Unique: Implements stateful synthesis with KV-cache reuse across text segments, preserving prosodic context without requiring full document re-encoding. Uses sentence-boundary detection and lookahead buffering to optimize segment boundaries for natural prosody transitions, avoiding the audio artifacts common in naive concatenation approaches.

vs others: Handles multi-hour documents with consistent prosody while remaining memory-efficient, unlike batch-only TTS (requires full text in memory) or cloud APIs (prohibitive cost for long-form synthesis).
