1. A method in a computer system for selecting a language model, the method comprising:
- operating the computer system to perform steps of;
collecting a plurality of language models;
collecting a set of corrected dictated reports;
comparing the corrected dictated reports with the plurality of language models;
determining a perplexity factor for each of the plurality of language models based on the comparison with the corrected dictated reports; and
selecting the one of the plurality of language models having the lowest perplexity factor.

10. A method in a computer system comprising:
operating the computer system to perform steps of; selecting a language model from among a plurality of factory language models; collecting site specific data from a user; transforming the selected language model into a site-specific language model by adding the site-specific data to the selected language mode; determining whether the user has an accent; creating an accent specific word list based on the user'"'"'s accent; and adding the accent specific word list to the site-specific language model. - View Dependent Claims (11, 12, 13)
