The most important process for the correct use of this software is the so-called ‘quick training, and ‘enrollment,: it consists of reading many specific words and sentences in order to make the software adapt itself to the specific users' sound and intonation features. It lasts for one hour or more and can be divided in many parts. Users are able to improve decoding accuracy, by reading prepared texts of a few hundred sentences. The recorded data was used to tune the acoustic model to that specific user. In addition, user specific text files could be parsed to tune the language model. Correction of mis-recognised words was also used to improve subsequent decode accuracy.
