27. The speech recognition method of claim 22 wherein the step of determining the preferred mix of the preclassification output data comprises the steps of: selecting a mix of the preclassification output data to obtain a predetermined satisfactory recognition accuracy in the least amount of time.
22. A speech recognition method comprising the steps of: processing first speech input signal data to preclassify the speech input signal and produce first preclassification output data, wherein the first speech input signal data represents a speech input signal; processing second speech input signal data to preclassify the speech input signal and produce second preclassification output data; determining when to include the first speech input signal, the second speech input signal, and a combination of the first and second speech input signals in a preferred mix of the preclassification output data by determining at least an appropriate balance between speech recognition accuracy and a speech recognition processing speed; mixing the first and second preclassification output data in accordance with the preferred mix; and classifying the speech input signal based on the preferred mix of preclassification output data.
