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.

One of the conspicuous technologies used for text to speech conversion is optical character recognition (OCR) that converts the text from the images or handwritten documents into machine-encoded text. This machine-encoded text can then be read aloud by the TTS tools. Prominent TTS tools encompass web-based tools, chrome tools, text-to-speech apps, text-to-speech software, etc. It is noteworthy that TTS is entirely computer-generated and therefore is suitable for working with every digital device capable of interaction, including computers, tablets, Smartphones, etc.
