What is Text to Audio Conversion?


Text-to-Speech (TTS) is an operative technology and language modelling process that reads digital text aloud. This converts units of text into units of speech. By providing an audio output it is the direct opposite of audio-to-text software and benefits those who have trouble reading. It takes words on a computer or any electronic device and converts them to speech. It is particularly helpful for kids to write, edit and focus. The instant messaging app, KalamTime includes text to audio conversion this convenient feature allowing improved communication with friends, family, clients etc.  

How Text-to-Speech Works

This technology can work on any electronic gadget be it computers, laptops, smartphones or tablets. It can convert text to audio for any file, even Word documents or online webpages. The voice may be computer-generated or sound human-like. The user can change the settings for even a child-like voice if needed. Voice quality can be modified by increasing or decreasing the speed of the sound. Furthermore, even the digital text that is being converted can be highlighted so that the user is aware of what text corresponds to what audio, eliminating any confusion. Interestingly, some TTS tools also have Optical Character Recognition (OCR) where text can be read aloud even from images. 

Challenges of Developing Text-to-Audio

In English Language a number of homonyms have different pronunciation so probability modelling is used to guess the pronunciation of a word in digital text. The computer program converts text to phonemes, the smallest units of speech pronunciation. To make text-to-audio technology error-free some practices for TTS development include phoneme bases, concatenative approaches such as synthesising sounds by concatenating short samples of recorded sound (called units) or through predictive analytics in which statistical data or algorithms are used to identify likely future outcomes from a database of historical data.
