Reduced speech intelligibility is a barrier to effective communication for many children with cerebral palsy (CP). Many variables may impact intelligibility, yet little research attention has sought to quantify these variables. This study examined the influence of sentence characteristics on intelligibility in two groups of children with CP (those with and without dysarthria) and typically-deve...

Text cues facilitate the perception of spoken sentences to which they are semantically related (Zekveld, Rudner, et al., 2011). In this study, semantically related and unrelated cues preceding sentences evoked more activation in middle temporal gyrus (MTG) and inferior frontal gyrus (IFG) than nonword cues, regardless of acoustic quality (speech in noise or speech in quiet). Larger verbal worki...

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...

Much of the research exploring the features of speech that distinguish intelligibility ratings has focused on monologic speech production. This study considers whether the use of specific interactive features in task-based interaction influences interlocutors' ratings of intelligibility. Five dyads completed an information gap task and rated their partners' intelligibility following task comple...

This study examined differences among transcription intelligibility scores and listener confidence ratings for three different types of speech stimuli--single words, unrelated sentences, and sentences forming a narrative--all produced by speakers with dysarthria. Twelve speakers with dysarthria of varying severity secondary to cerebral palsy and 144 listeners participated in this study. Results...

A study of speaker intelligibility involving 45 speakers from a homogeneous accent group was carried out with adult, 7-8 year old and 11-12 year old listeners. Ranking of speakers according to their intelligibility was remarkably consistent across listener groups, thus demonstrating that inherent speaker characteristics are the primary contributor to intelligibility. In a second study, listener...

Speech supplementation strategies (alphabet cues, topic cues, and combined topic and alphabet cues) have been shown to have a positive effect on speech intelligibility for many individuals with dysarthria, particularly those with severe and profound intelligibility deficits (Hustad, Auker, Natale, & Carlson, 2003a; Hustad, Jones, & Dailey, 2003b). However, less attention has been given to speak...

This paper examined the intelligibility of English / / and / / followed by the vowel / / produced by 20 native speakers of Japanese (JE / /, JE / /), and the acoustic characteristics of JE / / and / / according to the different levels of intelligibility. Five native English speakers evaluated the intelligibility of JE /s/ and / / in the word-initial position of “seat” and “sheet.” The major ene...

Instrumental measures of speech intelligibility typically produce an index between 0 and 1 that is monotonically related to listening test scores. As such, these measures are dimensionless and do not represent physical quantities. In this paper, we propose a new instrumental intelligibility metric that describes speech intelligibility using bits per second. The proposed metric builds upon an ex...
