Abstract
An apparatus and method for performing improved speech recognition in a communication terminal, e.g., a mobile phone with a hands-free voice dialing function. In a speech recognition mode, a user's input speech such as a desired called party name, number or a phone command, is converted to feature data and compared to individual pre-stored feature data sets corresponding to pre-recorded speech obtained during a registration process. Difference values representing the respective differences between the current user's input speech and the respective data sets are computed. A first closest (most similar) and second closest feature data set correspond to the first smallest and second smallest difference values so obtained. A closeness threshold is computed as the sum of a small, predetermined threshold and a differential value between the first and second difference values. If the first difference value is less than the computed closeness threshold, then the input speech is determined to match the first feature data set, whereby a positive speech recognition result is obtained. When a match occurs, an automatic dialing operation may be carried out in one application.
