Abstract: Speech recognition, especially the telephone speech recognition technique has been widely put into practice. We have built a telephone speech database covering most of the dialect area using the Dialogic card, and have constructed a voice-activated home banking service system by employing the HMM framework the test results of the system are also given in the paper.
