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.
