Speech recognition method and apparatus with automatic parameter selection based on hardware running environment
First Claim
1. A speech recognition method which carries out a speech recognition process on an input speech signal based on recognition parameters using recognition software, said speech recognition method comprising the steps of:
- (a) detecting at least one running environment provided by hardware which is to run the recognition software;
(b) determining recognition parameters depending on the running environment detected by said step (a); and
(c) carrying out the speech recognition process on the input speech signal based on the recognition parameters determined by said step (b) using the recognition software,said recognition parameters determining a quality of the speech recognition process.

Abstract
A speech recognition method and apparatus enable the use of the same recognition software for speaker dependent recognition under various running environments such as different computers. The speech recognition method operates in the form of computer software to detect at least one running environment of hardware. The hardware running environment may include processing speed of a computer. Recognition parameters are then determined which correspond to the detected running environment. Next, the speech recognition method converts an input analog speech signal into a digital speech signal. The digital speech signal, in the form of extracted feature data, is then compared with digital feature data in a dictionary. The speech is then recognized in response to a match of the data.
