Text-to-speech synthesizer in nine Indian languages
Funding agency: Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH
The SYSPIN project from SPIRE Lab, IISc, Bangalore, in collaboration with Bhashini AI Solutions, has released TTS corpuses in 9 Indian languages with 2 speakers (male and female) per language. Over 40 hours of speech per speaker were recorded, ensuring high quality through rigorous checks, including local and native speaker contributions. The SYSPIN dataset and baseline TTS models are now available for download, empowering innovations in sectors like agriculture, healthcare, education, and finance. SYSPIN aims to advance multilingual, multi-speaker TTS systems, and organized challenges under LIMMITS 23, 24, and 25 to support inclusive, accessible voice technologies in India.
