What is text to speech and how does it work?

Text to speech technology, commonly known as TTS, is the conversion of text into voice output. In the early days of TTS, it wasn't so efficient; however, the advent of deep learning entirely changed the scenario. As it stands, modern computers are capable of concatenating the speech from various databases. This speech or sound is synonymous with natural sounds and reacts to pitch, pronunciation, frequency, etc. Considering the fact that text to speech assistive technology excellently interprets the text and the associated speech constraints, it is widely employed by businesses to enhance the user experience.
