Abstract
A speech recognition system. The system includes at least one recognizer to produce output signals from audio input signals and a feedback module to collect feedback data generated from conversion of the audio input signals to output signals. The system stores the feedback data and may also be adapted to use the feedback data as part of a training set for recognizers in the system, as part of a predictive mechanism, or both.

16. A method of generating speech recognition feedback data, the method comprising:
-
converting an audio input signal to an output signal;
estimating a correctness measure wherein the correctness measure expresses if the output signal is a correct representation of the audio input signal; and
forming a feedback data element wherein the element consists of at least one of the audio input signal, the output signal, and the correctness measure. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. An article including machine-readable code that, when executed, causes a machine to:
-
convert an audio input signal to an output signal;
estimate a correctness measure wherein the correctness measure expresses if the output signal is a correct representation of the audio input signal; and
form a feedback data element wherein the element consists of at least one of the audio input signal, the output signal, and the correctness measure. - View Dependent Claims (26, 27, 28, 29)
