Ratings and reviews

I've tried the 'Voice Tra' app, and it's decent. However, the UI could definitely use some sprucing up, and the translations for a few languages need work.

Am impressed with the results, especially for short & clear sentences. I've done a quick comparison for several language pairs (English to & from Japanese, Spanish, French and Dutch) with Google Translate and found VoiceTra to be more accurate across the board and generally easier to understand. Too bad speech input is not (yet?) available for all the languages listed. I assume, and hope, that's because it's still a work in progress…

Taje it down....This app does not support a lot of northern European and Scandinavian languages. It is also very inaccurate when it does translate. When I spoke in to the microphone to autodetect my language wich I could only put Danish as the closest to my Swedish (no, not the same really) it translated it in to simplified Chinese!!! I am glad I tested this app before using it with friends from different Nationalities.
