Open-source text-to-speech (TTS) software has enabled the development of voices in multiple languages, including many high-resource languages, such as English and European languages. However, building voices for low-resource languages is still challenging. We describe the development of TTS systems for 12 Indian languages using the Festvox framework, for which we developed a common frontend for Indian languages. Voices for eight of these 12 languages are available for use with Flite, a lightweight, fast run-time synthesizer, and the Android Flite app available in the Google Play store. Recently, the baseline Punjabi TTS voice was built end-to-end in a month by two undergraduate students (without any prior knowledge of TTS) with help from two of the authors of this paper. The framework can be used to build a baseline Indic TTS voice in two weeks, once a text corpus is selected and a suitable native speaker is identified.
