Hindi Speech Recognition Data

From:Nexdata Date:2024-04-02

According to statistics, there were 528 million people in India who spoke Hindi as their mother tongue, accounting for 43% of India's total population that year. In addition, there are 163 million people who use Hindi as their second and third languages and have certain conversational skills. At the same time, there are millions of people using Hindi in the United States, South Africa, Singapore and other places. With the increasing international status of India, the influence of Hindi is gradually increasing.


In the field of speech technology, if you want to realize speech recognition of a language, you need enough training data. Due to the extreme scarcity of Hindi speech recognition resources, the development of Hindi speech recognition has encountered great challenges.

The scarcity of Hindi speech recognition resources is mainly reflected in the following two aspects:

1) Hindi speech recognition data are difficult to obtain, and a few open source data sets have a single field

2) There are few public codes, and the results in the literature are difficult to reproduce.

Facing the scarcity of Hindi speech recognition data, Nexdata has developed multiple sets of Hindi Speech Recognition Data. We hope that these training data can help more Hindi speech recognition applications to be implemented and improve the accuracy of Hindi speech recognition.
