Kashmiri TTS Dataset

Project Page | GitHub | Paper

Overview

This dataset is the Text-to-Speech (TTS) corpus for the Kashmiri language, as presented in the paper "Bolbosh: Script-Aware Flow Matching for Kashmiri Text-to-Speech".

The dataset is a derived and curated combination of Kashmiri speech data from the IndicVoices-R corpus and the RASA speech dataset. It was used to develop Bolbosh, an open-source neural TTS system designed to handle the specific orthographic and phonological challenges of the Kashmiri language.
