WordTalk has been around since 2007 and has been downloaded over 170,000 times.
It was conceived and developed by Rod Macaulay of TASSC in Aberdeen, Scotland who later received a Microsoft Innovative Teacher Award for its development.
For people with reading and writing difficulties, having text reinforced by hearing it read aloud can be very useful.
It is also useful for proof reading and learning another language.
The WordTalk toolbar sits neatly in Microsoft Word under the 'Add-Ins' tab.
You simply click you cursor where you want WordTalk to start and then press one of the first 4 buttons on toolbar to start speaking (entire document (bubble), paragraph (P), sentence (S) or word (W)).
WordTalk will now highlight a word as it is spoken.
