<p>A digital cellular phone with a voice recognition function recognizes a voice signal using components included therein. A vocoder compresses a voice signal input from a microphone to output packet data. A nonvolatile memory stores the packet data and feature data corresponding thereto. A voice recognition device extracts the feature data from the packet data output from the vocoder, and compares the feature data with feature data registered in the nonvolatile memory to detect the registered feature data similar to the input feature data and a difference value therebetween to determine whether an input voice signal is recognized successfully depending on the difference value.</p> |
