A method for managing voice registration entries of voice recognition apparatus for use in both a handset and a hands-free kit. In the method, it is determined whether the handset is set to a hands-free mode where the handset is mounted on a cradle, thus connecting with the hands-free kit. If the handset is set to the hands-free mode, a voice registration entry for the handset is compared with a voice registration entry for the hands-free kit to calculate an entry difference value therebetween. A voice recognition process is performed, if the entry difference value is a minimum value, e.g., substantially zero. If the entry difference is larger than the minimum value, then a voice entry is registered for the hands-free kit, in response to a user confirmation. If the entry difference is smaller than the minimum value, then the voice entry is registered for the handset, in response to a user confirmation.

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.
