Yo, been following the TTS space closely while building voice agents, and Lightning V3 genuinely surprised me. Getting real-time performance and natural prosody in the same model has always felt like a trade-off, this is the first time it hasn't. The multilingual support is a big deal for me as well. Congrats on the launch.

How are you handling voice cloning misuse? Any safeguards in place?
How well does it handle code-switching? Like mixing Hindi + English in the same sentence?
How is it different from ElevenLabs?
Voice cloning from 10 seconds of audio is impressive. We're doing something similar but for writing — Krafl-IO analyzes your LinkedIn posts and clones your writing voice so AI-generated posts sound like you wrote them. Different modality, same core challenge: Capturing someone's unique style. Congrats on #2!
I used the voice clone feature! I am able to use the realistic voices in videos that I create loving the experience.
