HOW THIS AFFECTS YOU
●
builderYou can self-host a context-aware TTS model on consumer hardware, removing dependency on cloud voice APIs for latency-sensitive or privacy-sensitive applications.
●
researcherWorth watching because the 6-minute context window for prosody/style coherence is a meaningful architectural claim worth benchmarking against existing open TTS systems.
