The voice processor will convert your speech into text sending Next your computer will send this meta speech to everyone who is on this website. Upon receiving this broadcast, each person’s computer will prepare the message and re-speak it in both text and in a simulated voice. This technology has been around and is still pretty new. Today you are able to test this technology yourself in your web browser. This Chat IM App is written in JavaScript and HTML5. The source code is listed lower in this page.

A commercially available TTS API called iSpeech gives access to a rather complex yet powerful API providing flexible voice control including gender and accents. iSpeech has many SDKs and cover nearly every mobile device. TTS may be used to read a book allowed while driving or help children to read at an early age.

STT Speech To Text is the opposite. Record your voice and your computer will interpret the words you have spoken and translate them onto your computer screen as plain text. Voice Controlled Systems use this kind of tech. Both STT and TTS are demonstrated on this page, in a web browser.
