PURPOSE The authors examined speech intelligibility in typically developing (TD) children and 3 groups of children with cerebral palsy (CP) who were classified into speech/language profile groups following Hustad, Gorton, and Lee (2010). Questions addressed differences in transcription intelligibility scores among groups, the effects of utterance length on intelligibility, the relationship betw...

A new speech intelligibility improvement method for near-end listening enhancement in noisy environments is proposed. This method improves speech intelligibility by optimizing energy correlation of one-third octave bands of clean speech and enhanced noisy speech without power increasing. The energy correlation is determined as a cost function based on frequency band gains of the clean speech. I...

In this paper, automatic dysarthria severity classification is explored as a tool to advance objective intelligibility prediction of spastic dysarthric speech. A Mahalanobis distance-based discriminant analysis classifier is developed based on a set of acoustic features formerly proposed for intelligibility prediction and voice pathology assessment. Feature selection is used to sift salient fea...

This paper attempts to establish the importance of differences in the tone inventories for the mutual intelligibility of 15 Chinese dialects. Tone influence for mutual intelligibility was tested in two studies. In the first study mutual intelligibility was measured through opinion testing. The fable “The North Wind and the Sun” was read by one male speaker in each of 15 Chinese dialects with me...

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...
