Use of espeak-ng command in linux
eSpeak is a command line tool for Linux that converts text to speech. This is a compact speech synthesizer that provides support to English and many other languages. It is written in C. eSpeak reads the text from the standard input or the input file. The voice generated, however, is nowhere close to a human voice. But it is still a compact and handy tool if you want to use it in your projects. Speaks text from a file or from stdin and Shared library version for use by other programs.
Features
