Jaipur’s IIT student builds world’s first speech-to-speech AI Model that can sing, whisper, feel

JAIPUR: Jaipur-based 25-year-old founder Sparsh Agrawal has unveiled one of the first speech-to-speech foundational AI models that can sing, whisper, pause, and respond with emotional intelligence — all developed without big-tech infrastructure or venture capital funding.

Launched under his startup Pixa AI, Luna AI directly processes audio to generate human-like speech instead of converting it to text and back, resulting in faster, more expressive, and emotionally aware conversations.
