This study investigated the effectiveness of using antecedent persuasive stimulation and response-contingent praise, within a small discussion group context, to modify the rate of verbal participation of Ss in an independent, classroom situation. Ss were 96 male college students who were divided into 12 treatment subgroups and 4 control subgroups of 6 Ss each. 3 treatment conditions were employ...

This paper uses listening tests to directly evaluate two speech pre-enhancement algorithms that were published in earlier work. The models were previously evaluated using purely objective measures. The methods under study aim to increase speech intelligibility by applying an adaptive spectral shaping filter to the speech signal. In both algorithms the shape of the filter is adapted so as to max...

Intelligibility of conversationally produced speech for normal hearing listeners was studied for three male and three female talkers. Four typical listening environments were used. These simulated a quiet living room, a classroom, and social events in two settings with different reverberation characteristics. For each talker, overall intelligibility and intelligibility for vowels, consonant voi...

INTRODUCTION Speech intelligibility, the ability to be understood verbally by listeners, is the gold standard for assessing the effectiveness of cochlear implantation. Thus, the goal of this study was to compare the speech intelligibility between normal-hearing and cochlear-implanted children using the Persian intelligibility test. MATERIALS AND METHODS Twenty-six cochlear-implanted children ...

the main goal of early detection of hearing impairment in children is early intervention. there is growing interest in early detection of hearing impairment in developing countries. the main purpose of this study was to investigate the spoken language development in severe to profound hearing impaired children and compared their speech intelligibility with normal hearing children at the same ag...

Intelligibility and degree of accentedness are interrelated aspects of non-native speech. Previous research suggests that foreign accentedness is influenced by phonetic distance measures [7]. These distance measures may also influence the intelligibility of individual words. In the present study we further investigate the relationship between the intelligibility of nativeand Mandarin-accented E...

The three mainland Scandinavian languages (Danish, Swedish and Norwegian) are so closely related that the speakers mostly communicate in their own languages (semicommunication). Even though the three West Germanic languages Dutch, Frisian and Afrikaans are also closely related, semicommunication is not usual between these languages. In the present investigation, results from intelligibility tes...

This study investigated acoustic-phonetic correlates of intelligibility for adult and child talkers, and whether the relative intelligibility of different talkers was dependent on listener characteristics. In experiment 1, word intelligibility was measured for 45 talkers (18 women, 15 men, 6 boys, 6 girls) from a homogeneous accent group. The material consisted of 124 words familiar to 7-year-o...

In the present investigation we aim to determine to which degree various linguistic factors contribute to the intelligibility of Swedish words among Danes. We correlated the results of an experiment on word intelligibility with eleven linguistic factors and carried out logistic regression analyses. In the experiment, the intelligibility of 384 frequent Swedish words was tested among Danish list...

Instrumental intelligibility metrics are commonly used as an alternative to intelligibility listening tests. This paper evaluates 12 existing monaural intrusive instrumental intelligibility metrics: SII, HEGP, CSII, HASPI, NCM, QSTI, STOI, ESTOI, MIKNN, SIMI, SIIB, and sEPSM. The intelligibility data used in the evaluation were obtained from ten listening tests described in the literature. The ...
