“Clear” (CLR) speech is a speaking style that speakers adopt to be understood correctly in a difficult communication environment. Studies have shown that CLR speech, as opposed to “conversational” (CNV) speech, has significantly higher intelligibility in various conditions. While many differences in acoustic features have been identified, it is not known which individual feature or combinations...

BACKGROUND intelligibility of phonological disorder. AIM to compare the intelligibility of phonological disorder analyzed by three distinct groups of judges. METHOD the research consisted of two samples: one sample was composed by 30 individuals with phonological disorder (assessed individuals) and the other sample was composed by the judges (speech-language therapists, laypeople and mother...

The noise influence to speech signal waveform can be characterized by reduced speech dynamic range (rDR). This motivated the present work to propose an rDR-based intelligibility measure (denoted as rDRm) that could be used to non-intrusively (i.e., do not require clean reference speech signal) predict speech intelligibility in noise and is computed only using the dynamic range extracted from th...

Dysarthria is a motor speech impairment affecting millions of people. Dysarthric speech can he far less intelligible than that of non-dysarthric speakers, causing significant communication difficulties. The goal of this work is to understand the effect that certain modifications have on the intelligibility of dysarthric speech. These modifications are designed to identify aspects of the speech ...

Despite advances in engineering noise controls and the use of administrative controls, miners are still dependent on hearing protection devices for prevention of noise-induced hearing loss. However, miners often raise concerns about the audibility of spoken communication when wearing conventional hearing protectors. Electronic technologies that selectively process and restore sounds from outsid...

OBJECTIVE To examine the impact of classroom placement and mode of communication on speech intelligibility scores in children aged 8 to 9 years using multichannel cochlear implants. DESIGN Classroom placement (special education, partial mainstream, and full mainstream) and mode of communication (total communication and auditory-oral) reported via parental rating scales before and 4 times afte...

In adverse listening conditions, talkers can increase their intelligibility by speaking clearly [Picheny, M.A., et al. (1985). J. Speech Hear. Res. 28, 96-103; Payton, K. L., et al. (1994). J. Acoust. Soc. Am. 95, 1581-1592]. This modified speaking style, known as clear speech, is typically spoken more slowly than conversational speech [Picheny, M. A., et al. (1986). J. Speech Hear. Res. 29, 43...

In studying speech intelligibility in traffic noise, I was able to reproduce a sound field with considerable reality by reproducing both speech and traffic noises by the speaker method using a CD. As a result, the following conclusions were reached. 1) The influence of noise on speech intelligibility is similar for the single syllable and adult disyllable in normal persons. 2) The influence of ...

Current interactive systems that rely on machine learning techniques have little, if any, support for intelligibility. That is, users are unable to ask why a machine learning system made a particular prediction or classification, or why it suggested a particular action be taken. In our work, we look at the need for intelligibility in machine learning (and other complex) systems, and mechanisms ...
