Original Abstract

We investigate and compare several techniques for automatic recognition of unconstrained context-independent phoneme strings from TIMIT and NTIMIT databases. Among the compared techniques, the technique based on TempoRAl Patterns (TRAP) achieves the best results in the clean speech, it achieves about 10\% relative improovements against baseline system. Its advantage is also observed in the presence of mismatch between training and testing conditions. % when %using both the high-quality TIMIT and the telephone-quality NTIMIT databases. Issues such as the optimal length of temporal patterns in the TRAP technique and the effectiveness of mean and variance normalization of the patterns and the multi-band input the TRAP estimations, are also explored.

Key words in English
