I have used this software for a while. It is very comprehensive. It is not a "cure all". You are unlikely to sound a native speaker after a week. it does provide way to work on the accent so you get to the point you do not get those stares and polite "excuse me".
The software is not very friendly. It is based on the phonetic alphabet, that can express in writing any sound in any language. I recommend starting from listening to the consonants and vowels in the software, especially those that do not exist in your native tongue, and learn to differentiate. Than listen to the words under each sounds - dedicate more time those that are challenging for you. Last, but not least, you can create a list of words you use on daily basis - depend on your profession - and go over them until you get them right.
The service is excellent. whenever I struggled with something, the email reply came within hours, sometime less than an hour.
No, I am not one of the developers. and I am not paid by the developer either for writing this review.
True, the software is not perfect; however, after checking few others , this is the best I came across. Those of us the struggle with the accent, know what it means finally to be understood. yes, if you put time into it, it works.
