Mundari TTS Dataset Corpus

This dataset contains 26,870 recordings of Mundari speech, spoken by two different speakers (one female and one male). It is released under the non-commercial version of the Karya Public License. Please read the "License" section below for a high-level summary of what you are allowed and not allowed to do under this license. This corpus was created by Microsoft Research India, the Indian Institute of Technology Kharagpur, and Karya in collaboration with the project of Indo-German Development Cooperation “FAIR Forward – Artificial Intelligence for all”. FAIR Forward is being implemented by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) on behalf of the Federal Ministry for Economic Cooperation and Development (BMZ).

Data Description

The Mundari TTS dataset corpus contains a total of 26,870 audio files, each containing a single utterance spoken by one of the two speakers. The audio is recorded in 32-bit PCM format with a sampling rate of 44.1 kHz. The dataset includes transcripts for each audio file in Mundari script. The recordings were collected in a sound-treated room using a high-quality microphone and preamp.

Speakers

The Mundari TTS dataset corpus includes recordings from two different speakers: a female speaker and a male speaker. The female speaker contributed 19,868 recordings, while the male speaker contributed 7,002 recordings.

The total size of the corpus is approximately 17 GB (7 GB compressed). Therefore, the full dataset is hosted in cloud storage (instead of this github repository). This repository contains a sample of 100 recordings from each speaker. Please email [email protected] for a link to download the full dataset.
