objective: the aim of the present research was to compare the auditory perception and verbal intelligibility in children with cochlear implant, hearing aids and normal hearing. methods: 60 children aged 5-7 years were divided to three groups and each group contained 20 children. the first and second groups were selected ordinarily from children with cochlear implant and hearing aids by convenie...

Previous studies have shown that "clear" speech, where the speaker intentionally tries to enunciate, has better intelligibility than "conversational" speech, which is produced in regular conversation. However, conversational and clear speech vary along a number of acoustic dimensions and it is unclear what aspects of clear speech lead to better intelligibility. Previously, Kain et al. [J. Acous...

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 ...

This review article provides an overview of differences between conversational (or cnv) and clear (or clr) speech, for a variety of speakers, in terms of speech intelligibility, and in terms of acoustic characteristics. Researchers have studied the relationship between acoustic features and speech intelligibility by, for example, studying correlations. However, the question “which acoustic feat...

The intelligibility of vocoded speech with various phase spectra was compared to the intelligibility of the original input natural speech. It was found that vocoded speech with true natural phase was the closest to natural speech in intelligibility.

In this paper, we propose an algorithm which enhances the speech intelligibility using the properties of human auditory system. In previous algorithms related to the speech intelligibility, the improvement in intelligibility has been mostly incorporated in a single-channel environment where the speech and noise signals are mixed together. But the speech enhancement problem of dual channel, in w...

UNLABELLED The current study was undertaken to investigate the impact of speech motor issues on the speech intelligibility of children with moderate to severe speech sound disorders (SSD) within the context of the PROMPT intervention approach. The word-level Children's Speech Intelligibility Measure (CSIM), the sentence-level Beginner's Intelligibility Test (BIT) and tests of speech motor contr...
