  • Progress in technology over the recent years has seen a number of innovations designed to help differently abled people function more successfully. The IT sector has grown by leaps and bounds, and developers have ensured that all audiences, including gifted persons, continue to enjoy complete access to the internet. Text to Speech (TTS) is one such innovation that has helped millions of people overcome difficult challenges and take a step closer to functioning normally. In order to encourage accessibility and engage all visitors to websites, an increasing number of publishers are now developing pages in line with the Web Content Accessibility Guidelines (WCAG) 2.0 and other similar programs. Now that web content complies with these standards, a number of assistive technologies can be used to help visitors work well. One of these technologies is Google Text-to-Speech; an easy to install extension for Mozilla Firefox that auto detects a language and converts it to speech in natural sounding voices.

    Available with an easy one click install procedure, and by using JavaScript TTS API, this Text to Speech tool can be enabled by using your mouse and clicking on any word or sentence. Once active, it highlights selected text paragraph-by-paragraph and users are able to hear the content instantly. While it is still being developed, and functionality in other languages is just around the corner, the tool is excellent for covering all types of English articles and content. Currently, the supported languages by TTS Addon includes, Cantonese (Hong Kong), Chinese (China), Dutch, English (India), English (United Kingdom), English (United States), French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Spanish (Spain), Spanish (United States) Thai (Thailand), and Turkish (Turkey). Some users have reported a limit error which requires Google TTS API to be restarted or the page to be refreshed. However, native HTML5 Text to Speech functionality is available to counter this issue. In order to enable HTML5 TTS, users should follow these steps. In Firefox, please go to "about:config" page. Then search for "webspeech" and locate "media.webspeech.synth.enables", then right click it and click Toggle to enable it. Despite this small issue in functionality, Google Text-to-Speech is ranked with 4 stars out of 5 in Mozilla Addon Store, and future updates promise to make this tool even more powerful.
