When started for the first time, WSR presents a microphone setup wizard and an optional interactive step-by-step tutorial that users can commence to learn basic commands while adapting the recognizer to their specific voice characteristics; the tutorial is estimated to require approximately 10 minutes to complete. The accuracy of the recognizer increases through regular use, which adapts it to contexts, grammars, patterns, and vocabularies. Custom language models for the specific contexts, phonetics, and terminologies of users in particular occupational fields such as legal or medical are also supported. With Windows Search, the recognizer also can optionally harvest text in documents, email, as well as handwritten tablet PC input to contextualize and disambiguate terms to improve accuracy; no information is sent to Microsoft.
