Speech to Text is the ability to convert spoken word to text. There are many speech to text conversion applications available for different languages. Tamil is an ancient classical language which is vastly spoken in southern parts of India, Sri Lanka, Malaysia, and Singapore. The speech to text application is designed from an indigenous perspective to enable the native speakers to preserve their linguistic heritage. The application was developed using agile methodology and the testing of the application suggested that the existing API do not support in the notion of preserving the language in its original form.
