1. A speech recognition method, comprising:
- (a) receiving, by an input port, a first voice utterance from a user, the first voice utterance comprising at least a first utterance component;
(b) determining, by speaker monitoring agent, a pulmonary state of the user at an approximate time when the first voice utterance was made, wherein the first and second pulmonary states indicate at least one of an amount of air in the user'"'"'s lungs, a degree of expansion of the user'"'"'s lungs, and a forcefulness with which air is exhaled;
(c) applying, by a frame analyzer, the following rules;
(C1) when the user had a first pulmonary state when the first voice utterance was made, using a first algorithm to identify a potential match for the voice utterance; and
(C2) when the user had a second pulmonary state when the first voice utterance was made, using a second different algorithm to identify a potential match for the first voice utterance.

Abstract
A speech recognition system is provided that, in one embodiment, includes an input 104 operable to receive voice utterances from a user, a speaker monitoring agent 132 operable to determine a pulmonary state of the user as a function of time, and a frame analyzer 120 operable to (i) determine a respective pulmonary state of the user at an approximate time when each of the voice utterances was made and (ii) process each of the voice utterance in a manner dependent upon the respective pulmonary state.

11. A speech recognition method, comprising:
-
(a) receiving, by an input, a voice utterance from a user, the voice utterance comprising at least a first utterance component, wherein the first utterance component is of a first speech type; (b) determining, by a speaker monitoring agent, a state of the user at an approximate time when the voice utterance was made; (c) applying, by a frame analyzer, the following rules; (C1) when the user had a first state when the voice utterance was made, at least one of (i) determining a first level of confidence of a selected match for the voice utterance being correct and (ii) comparing the first level of confidence against a first determined confidence level to determine whether to query the user for input respecting the selected match; and (C2) when the user had a second state when the voice utterance was made, at least one of (i) determining a second level of confidence of the selected match for the voice utterance being correct and (ii) comparing the first and/or second level of confidence against a second determined confidence level to determine whether to query the user for input respecting the selected match, wherein the first level of confidence is different from the second level of confidence and the first determined confidence level is different from the second determined confidence level; wherein the first and second states indicate at least one of an amount of air in and a degree of expansion of the user'"'"'s lungs. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A speech recognition system comprising:
-
(a) an input for receiving voice utterances from a user; (b) a speaker monitoring agent for determining a pulmonary state of the user as a function of time, wherein the first and second pulmonary states indicate at least one of an amount of air in the user'"'"'s lungs, a degree of expansion of the user'"'"'s lungs, and a forcefulness with which air is exhaled; and (c) a frame analyzer for (i) determining a respective pulmonary state of the user at an approximate time when each of the voice utterances was made and (ii) processing each voice utterance in a manner dependent upon the respective pulmonary state. - View Dependent Claims (20, 21, 22, 23, 24, 25)
