Isolated Word Recognition

This study examined the effects of forward time gating and word length on monosyllabic isolated word-recognition performance. Fifty (60-ms) time-gated words were developed from a pre-recorded version (Auditec of St. Louis) of the Northwestern Auditory Test No. 6 (NU-6) List 1, Form A. A total of 358 time-gated items were presented monaurally at 80 db SPL, and time-gated word identification, isolation point, acceptance point, and listener confidence measures were obtained from 20 normally hearing listeners. A comparison of conventional nontime-gated word-recognition scores obtained using the NU-6 List 4, Form C with the time-gated measures revealed that, even upon word offset, listeners recognized time-gated words less frequently and with less confidence. The time-gated findings also demonstrated that word length, based on word duration from onset to offset, significantly influenced real-time recognition performance.

Time Assessment

This investigation was designed to study real-time isolated monosyllabic word-recognition performance and the feasibility of applying time-gated NU-6 word-recognition test materials for real-time assessment of older listeners. Methods and materials developed in a previous investigation were used to obtain time-gated performance measures from 37 older listeners (mean age=69 years). The older listener performance measures were compared with extant data from 20 normally hearing young adult listeners (mean age=22 years). Specifically, listener confidence and accuracy by gate as well as listener isolation point, confidence at the isolation point, and total acceptance point measures were evaluated. The results show that major events in the real-time understanding process occur at a slower pace among older listeners. The data indicate that the time-gating method has excellent potential for future research among elderly listeners.

Isolated Word Recognition

AbstractIn this commentary we concur with Frost's view of the centrality of universal principles in models of word identification. However, we argue that other processes in sentence comprehension also fundamentally constrain the nature of written word identification. Furthermore, these processes appear to be universal. We, therefore, argue that universality in word identification should not be considered in isolation, but instead in the context of other linguistic processes that occur during normal reading.

In this paper, we proposed a new noise speech recognition method based on the compressive sensing theory. Through compressive sensing, our method increases the anti-noise ability of speech recognition system greatly, which leads to the improvement of the recognition accuracy. According to the experiments, our proposed method achieved better recognition performance compared with the traditional isolated word recognition method based on DTW algorithm.
