Abstract: Techniques for performing speech recognition in a communication device with a voice dialing function is provided. Upon receipt of a voice input in a speech recognition mode, input feature vectors are generated from the voice input. Also, a likelihood vector sequence is calculated from the input feature vectors indicating the likelihood in time of an utterance of phonetic units. In a warping operation, the likelihood vector sequence is compared to phonetic word models and word model match likelihoods are calculated for that word models. After determination of a best-matching word model, the corresponding number to the name synthesized from the best-matching word model is dialed in a dialing operation.
