Abstract
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.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
95 words
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.
Claim 2
Dependent Claim
95 words
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.
Claim 3
Dependent Claim
64 words
The method according to claim 1 further comprising the steps of: retrieving pronunciations of the out-of-vocabulary words from a pronunciation database; generating pronunciations of the out-of-vocabulary words not having pronunciations in the database; updating the system's vocabulary to temporarily include the retrieved and generated pronunciations; and removing from the system's vocabulary the retrieved and generated pronunciations after dictation of the responsive body of text.
Claim 4
Dependent Claim
45 words
The method of claim 2 wherein the out-of-vocabulary words, and the retrieved and generated pronunciations are removed from the system's vocabulary following an interval beginning after dictation of the responsive body of text and running for a period of time calculable in a predetermined manner.
Claim 5
Dependent Claim
51 words
The method according to claim 1 further comprising the steps of: generating context information from the available body of text; updating the system's language model to temporarily include the context information; and removing the context information generated from the available body of text after dictation of the responsive body of text.
Claim 6
Dependent Claim
40 words
The method of claim 4 wherein the context information updates are removed from the language model following an interval beginning after dictation of the responsive body of text and running for a period of time calculable in a predetermined manner.
Claim 7
Dependent Claim
34 words
The method according to claim 1 further comprising the step of determining whether a user's spoken command decodes into a command indicative of a situation where the user is responding to an E-mail message.
Claim 8
Dependent Claim
21 words
The method of claim 1 wherein the available body of text comprises a received E-mail message's body in plain text format.
Claim 9
Dependent Claim
21 words
The method of claim 1 wherein the dictated body of text comprises an E-mail message responsive to a received E-mail message.
Claim 10
Independent Claim
95 words
A system for dictating a body of text in response to an available body of text comprising: means for retrieving from a memory the available body of text; means for 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; means for updating the system's vocabulary to temporarily include the out-of-vocabulary words; means for dictating the responsive body of text; and means for removing the out-of-vocabulary words from the system's vocabulary after dictating the responsive body of text.
Claim 11
Independent Claim
95 words

Claim 12
Dependent Claim
69 words
