Text-to-Speech (TTS) is the conversion of digital text into a computer synthesised spoken message. Originally developed to help people with a visual impairment, computers could ‘read aloud’ any text that was typed.
Synthesised speech is now widely used in technology, business, government, academic and disability applications – examples include Sat Nav systems telling you where to go; talking smartphones telling you about the weather; or low-vision software reading the contents of your screen to you. For people who cannot speak, computer generated speech can also become their way of communicating.
The uses are many and varied. Anybody using computer generated speech for any purpose, will now be able to have messages produced by this affordable software, in local South African languages, including English with a South African accent. No longer will you need to spend a lot of money and time on human recordings of hundreds of messages, or rely on internationally accented speech synthesis. Local really is lekker.
How does it work?
Speech synthesis is usually created by collecting a huge database of recorded speech in a certain language. Narrators would read from a variety of texts, in order to have a full and varied collection of sounds, aiming to include every possible sound from that language in the database.
Those recordings are then ‘sliced’ up into tiny sound pieces, which represent vowels, phonemes, consonants etc. and the way they vary in different contexts. A sophisticated analysis then takes place, matching those sounds to written words. Once a voice is created, it knows how to pronounce the words and sounds from that particular language, and can read text aloud in a natural sounding way.
When computers, smartphones, answering systems etc. speak to us, they are simply using a synthesised voice to read a portion of text aloud.
