Device for Modifying and Improving the Behaviour of Speech Recognition Systems
First Claim
1. A speech recognition system comprisinga controller application having an output arranged to produce a speech signal, an input arranged to receive a recognized speech result signal, and a control command output arranged to produce a command signal;
- a speech recognizer having a pattern matcher, a speech input arranged to receive the speech signal from the controller application, an output arranged to produce the recognized speech result signal and a control command input arranged to receive the command signal,characterised by a modification apparatus disposed between the output of the controller application and the input of the speech recognizer;
between the output of the speech recognizer and the input of the controller application; and
between the control command output of the controller application and the control command input of the speech recognizer, the modification apparatus arranged to modify at least one of the signals between the controller application and the speech recognizer.

Abstract
A speech recognition system comprises a controller application, a speech recogniser, and a modification apparatus disposed between them. The controller application has an output arranged to produce a speech signal, an input arranged to receive a recognised speech result signal and a control command output arranged to produce a command signal. The speech recogniser has a pattern matcher, a speech input arranged to receive the speech signal from the controller application, an output arranged to produce the recognised speech recognised signal and a control command input arranged to receive the command signal. The modification apparatus is disposed between the output of the controller application and the input of the speech recogniser; between the output of the speech recogniser and the input of the controller application; and between the control command output of the controller application and the control command input of the speech recogniser. The modification apparatus is arranged to modify at least one of the signals between the controller application and the speech recogniser. In this way speech recognition accuracy can be significantly improved.
