It’s not actually phonetics, but my colleague Bas Aarts asks me to tell you about iGE, the interactive Grammar of English that the Survey of English Usage at UCL has developed.
It is an app for the iPhone, iPod, and iPad. (Since my mobile is an Android phone and I have no Apple products, I haven’t been able to try it out myself.)
As you can see, it offers a “complete” grammar of English, incorporating an extensive glossary, a guided course of instruction, and interactive exercises and puzzles. There’s a cut-down version that is free and a full version that costs a modest £4.99/$6.99/€5.49.
There was a report in Tuesday’s Evening Standard.
So — who’s going to be the first to fill the gap in the market for something similar dealing with English phonetics? Currently there are various monolingual and bilingual dictionaries available for your mobile/cellphone/handy, some with spoken versions of the headwords, but no specialist pronunciation dictionary.
