Abstract
Accurate speech understanding is crucial in everyday life. Yet, speech is often degraded by a variety of talker and environmental factors, which listeners must overcome. In this online experiment, we assess how degraded speech intelligibility is supported by "elemental" cognitive processes. Eighty-nine healthy adults listened to spoken sentences degraded in five ways and reported the words that they heard. In addition, they completed the Reading Span and N-back tasks to assess working memory capacity (WM), as well as a short version of Raven's Advanced Progressive Matrices to assess fluid reasoning ability. In bivariate correlational analyses, all cognitive test scores predicted degraded speech intelligibility. However, multivariate and dominance analyses revealed that the test of fluid reasoning was the most important predictor of intelligibility. These results may undermine the assumption that WM, as measured by the Reading Span and other tasks, is the primary cognitive construct supporting degraded speech intelligibility.
Speech perception during face-to-face conversations is perhaps the most functionally significant aspect of multisensory processing in people's everyday lives. Although they may not be aware of it, people use lipreading to both supplement auditory processing under poor listening conditions and compensate for age-related...

Difficulty perceiving speech in noise is the primary complaint of patients seeking hearing healthcare, even absent overt losses in audiometric thresholds. Yet current clinical practice largely focuses on sensory function while ignoring the potentially outsized effects of executive function on everyday suprathreshold li...

Current speech comprehension assessments do not provide a reliable measure of listeners' real-life speech comprehension ability, as they fail to capture the complexity and dynamic nature of real-world communicative scenarios. To better align laboratory assessment with real-world listening demands, we developed a new sp...

Elderly listeners with normal hearing to moderate hearing loss could maintain relatively high intelligibility for mosaic words segmented in blocks of 20 or 40 ms, provided the words had a high familiarity level.

PURPOSE
While an emerging body of research has demonstrated that late talkers (LTs) show continued subclinical deficits in language abilities, less is known about their development of speech production skills. The current study investigated speech production abilities among 3-year-old children with a history of late ta...

Neural encoding of acoustic and linguistic features of continuous speech is sensitive to cognitive factors, such as attention and comprehension. We investigated whether neural tracking is also sensitive to the predictability of speech. Participants were repeatedly exposed to intelligible or unintelligible versions of t...
