Abstract:     A system and method is delineated for dictating a body of text in response to an available body of text. In the preferred embodiment, the available body of text comprises only the textual body in plain format from a received E-mail message, while the responsive body of text preferably comprises a dictated E-mail response. Each word from the selected text of the received E-mail message is compared against the speech recognition system's vocabulary to determine whether any words are out-of-vocabulary. Out-of-vocabulary words and their pronunciations are added to the system vocabulary. Similarly, new context information is extracted from the selected text of the received E-mail message, and used to update the system's language model. Thereafter, the user more accurately and efficiently dictates the responsive E-mail, and the system removes the updates to the system vocabulary and language model.

What is claimed is:     1. In a computer system for speech recognition, a method for dictating a body of text in response to an available body of text comprising the steps of:
  • retrieving from a memory the available body of text;
  • identifying out-of-vocabulary words from the available body of text by comparing each word from the available body of text against words in the speech recognition system's vocabulary;
  • updating the system's vocabulary to temporarily include the out-of-vocabulary words;
  • dictating the responsive body of text; and
  • removing the out-of-vocabulary words from the system's vocabulary after dictating the responsive body of text.
