Abstract

An apparatus for receiving spoken input training words and for subsequently recognizing a spoken input command word. For each training word, and for the command word, there is stored a time dependent array and a cumulative feature non-time-dependent vector. The command word array is compared, member-by-member, with each training word array. Also, the command word vector is compared, feature-by-feature, with each training word vector. The results of both comparisons are used for selecting the training word which most closely matches the command word.
