As a part of the SYSPIN project, we are releasing 40 hours of studio recorded Telugu female TTS data. Validated audio and text files are made available to the public. This will open up opportunities for academic researchers, students, small and large-scale industries and research labs to innovate and develop algorithms and text-to-speech synthesizers in all the nine Indian languages included in this project proposal. It will also bring competitiveness among different research groups in coming up with ideas for developing high-quality synthesized speech to improve voice-based services. Open voice data is the foundation for local AI innovators to build applications that are geared towards the specific capabilities and requirements of users in India.

The SYSPIN Telugu Male TTS Dataset is a single-speaker, studio-recorded, read-speech corpus for Text-to-Speech (TTS) synthesis in the Telugu language, spoken by a professional male voice artist. It is one of eighteen speaker-language datasets produced under the SYSPIN (SYnthesizing SPeech in INdian languages) initiative — a large-scale, open-source effort by SPIRE Lab at IISc Bengaluru to build high-quality TTS corpora across nine Indian languages: Bengali, Bhojpuri, Chhattisgarhi, Hindi, Kannada, Magahi, Maithili, Marathi, and Telugu
