IndexTTS Workflow Studio adds multi-speaker TTS

This is less a raw TTS breakthrough than a workflow upgrade, and that is what makes it useful. If the tool stays reliable, it turns IndexTTS2 from a model demo into something closer to a production editor for dialogue-heavy audio.

• –Multi-speaker conversation handling is the real value here; stitching dialogue manually is where many TTS pipelines get painful fast.
• –Instant regeneration and review tools reduce iteration time, which matters more than small gains in synthesis quality for podcasts, games, and audiobooks.
• –The local-only Docker setup is a strong privacy and offline-use angle, but it also raises the bar for install and hardware setup.
• –Speaker preparation and cloning tools suggest the project is aiming at end-to-end production workflows, not just one-shot generation.
• –Timeline controls for overlaps and timing are the difference between “generated clips” and something editors can actually shape.
