Our Commentary ​

This is genuinely exciting for anyone working with AI audio. The ability to have 'granular audio tags' for precise control over expressiveness in TTS is a game-changer. It moves beyond just selecting a voice to truly directing the nuance and emotion of the speech. I can imagine this opening up so many possibilities for more natural-sounding voice assistants, immersive storytelling, and accessible content. It feels like we're getting closer to AI speech that doesn't just sound human, but can convey intent and emotion with real fidelity.
