First Claim
Patent Images
1. A speech dialog system, comprising:
- a signal pre-processor unit configured to process a speech input signal and generate an enhanced speech signal and an analysis signal, where the analysis signal comprises information related to one or more non-semantic characteristics of the speech input signal;
a speech recognition unit configured to receive the enhanced speech signal and generate a recognition result based on the enhanced speech signal; and
a control unit configured to receive the analysis signal and control an output unit or an external device based at least in part on the information of the analysis signal.

Abstract
A speech dialog system interfaces a user to a computer. The system includes a signal pre-processor that processes a speech input to generate an enhanced signal and an analysis signal. A speech recognition unit may generate a recognition result based on the enhanced signal. A control unit may manage an output unit or an external device based on the information within the analysis signal.
