Connected word recognition using a level building dynamic time warping algorithm

Abstract: The technique of dynamic time warping has proven itself reliable and robust for a wide variety of isolated word recognition tasks. Recently extensions of the algorithm have been investigated for application to the problem of connected word recognition. In this paper a level building technique is proposed for optimally aligning a test pattern, consisting of a sequence of connected words, with a sequence of isolated word reference patterns. This algorithm is shown to be significantly more efficient than the one proposed by Sakoe while solving the exact same problem. Implementation parameters for the level building algorithm are presented and the effectiveness of the proposed algorithm for connected digit recognition is experimentally verified.

Experiments on an isolated-word recognition system for multiple speakers

Abstract: The paper describes isolated-word recognition experiments on a multi-speaker speech recognition system. The system is organized in two main stages. At the phonemic recognition stage the phonemic transcription of the speech waveform is produced by simultaneous segmentation and labeling accomplished by the Learning Subspace Method. It directly produces an approximately correct number of phonemes. At the word recognition stage Redundant Hash Addressing is used for fast comparison of the phonemic transcriptions with referent strings stored in a dictionary. The average word recognition accuracy in a 200-word experiment with five speakers was about 95 per cent.
