Abstract:

In the present investigation we aim to determine to which degree various linguistic factors contribute to the intelligibility of Swedish words among Danes. We correlated the results of an experiment on word intelligibility with eleven linguistic factors and carried out logistic regression analyses. In the experiment, the intelligibility of 384 frequent Swedish words was tested among Danish listeners via the Internet. The choice of eleven linguistic factors was motivated by their contribution to intelligibility in earlier studies. The highest correlation was found in the negative correlation be

Abstract:

Listeners' glosses of children's intended words provided data for two studies of the potential influence of selected contextual and linguistic variables on word intelligibility. Several regularities associated with the occurrence of unintelligible words were identified. In Study I, intelligibility outcomes were associated with utterance length and fluency, word position, intelligibility of adjacent words, phonological complexity, and grammatical form. In Study II, intelligibility outcomes were associated with phonological complexity, syllabic structure, and grammatical form. Discussion conside

This study investigated several factors presumed to influence the intelligibility of song lyrics. Twenty-seven participants listened to recordings of musical passages sung in English; each passage consisted of a brief musical phrase sung by a solo voice. Six vocalists produced the corpus of sung phrases. Eight hypotheses derived from common phonological and prosodic principles were tested. Intelligibility of lyrics was degraded: (i) when archaic language was used; (ii) when words were set in melismatic rather than syllabic contexts; (iii) when the musical rhythm did not match the prosodic spee

Abstract:

Hospital noise often exceeds recommended sound levels set by health organizations leading to reductions in speech intelligibility and communication breakdowns between doctors and patients. However, quantifying the impact of hospital noise on intelligibility has been limited by stimuli employed in prior studies, which did not include medically related terminology. To address this gap, a corpus of medically related sentences was developed. Word frequency, word familiarity, and sentence predictability, factors known to impact intelligibility of speech, were quantified. Nearly 700 words were selec

Abstract:

This study evaluated the relationship between specific acoustic features of speech and perceptual judgments of word intelligibility of adults with cerebral palsy-dysarthria. Use of a contrasting word task allowed for intelligibility analysis and correlated acoustic analysis according to specified spectral and temporal features. Selected phonemic contrasts included syllable-initial voicing; syllable-final voicing; stop-nasal; fricative-affricate; front-back, high-low, and tense-lax vowels. Speech materials included a set of CVC stimulus words. Acoustic data are reported on vowel duration, forma

Abstract:

The relation between rated intelligibility and correct key word repetitions of sentences was examined in listeners with normal hearing and listeners with hearing loss. Ten lists of 10 CID sentences were arranged in two randomly ordered groups. Listeners were asked to complete two tasks: (1) rate the intelligibility of 50 sentences on a scale of 0 to 100%, and (2) repeat each of the 50 sentences, which were scored as the number of key words repeated correctly. Sentences were presented at five signal-to-noise ratios. The start level for sentence presentation was established using the method of a

Abstract:

The purpose of this study is to estimate subjective word intelligibility using DNN-based speech recognition. The evaluation of intelligibility is important to guarantee high speech quality in ambient noise and reverberation. The Japanese Diagnostic Rhyme Test (JDRT) is one such subjective evaluation method. In this study, we estimated Japanese word intelligibility by simulating the JDRT with cloud-based speech recognition systems. Recent DNNs can improve recognition accuracy with their robust classification ability and efficient use of high-dimensional features. We built a DNN-based speech rec

Summary descriptions are included for 19 procedures that have been, or could be, used to assess the intelligibility of pediatric subjects. Most procedures can be placed in one of the following categories, depending on the emphasis of the analysis: phonetic contrast analysis, phonological process analysis, word identification tests, phonetic indices derived from continuous speech scoring, scaling of continuous speech, and traditional word-level analysis of continuous speech. The general discussion includes an examination of the major issues to be considered in intelligibility testing and a set

Abstract:

This study was purposely conducted to determine what linguistic features affect the intelligibility of the Vietnamese speakers. To do this, speech samples of exemplars of Vietnamese English were audio-taped and then listened to by representatives of the Kachruvian circles, who wrote down what they heard. The findings show that Vietnamese speakers have some difficulties producing English words properly, especially with final sounds, word-final consonant clusters, and words that have more than three syllables. The exemplars also find it difficult to deal with the stress time rhythm of English wo

Assessment of the level of speech information protection from leakage through acoustic and vibration channels is carried out according to international and national standards and in compliance with regulatory documents. To assess its security level, regulatory documents in many countries imply the use of signal/noise ratio. However, the method has a series of significant shortcomings, which do not make it possible to determine the real state of security level.

Purpose Reductions in articulatory working space and vocal intensity have been linked to intelligibility deficits in children with dysarthria due to cerebral palsy. However, few studies have examined the outcomes of behavioral treatments aimed at these underlying impairments or investigated which treatment cues might best facilitate improved intelligibility. This study assessed the effects of cues targeting clear speech (i.e., “Speak with your big mouth”) and greater vocal intensity (i.e., “Speak with your strong voice”) on acoustic measures of speech production and intelligibility.

Abstract:

This study explores the production and perception of word-final devoicing in German across text-to-speech (from technology used in common voice-AI “smart” speaker devices—specifically, voices from Apple and Amazon) and naturally produced utterances. First, the phonetic realization of word-final devoicing in German across text-to-speech (TTS) and naturally produced word productions was compared. Acoustic analyses reveal that the presence of cues to a word-final voicing contrast varied across speech types. Naturally produced words with phonologically voiced codas contain partial voicing, as well

ABSTRACT The present study aims to investigate how the intelligibility of non-target word-final codas is affected by the type of coda modification, the degree of semantic information, and the listeners’ first language (L1). Furthermore, a correlational approach is adopted to examine possible relations between intelligibility and the listeners’ second language (L2) proficiency level, familiarity with speakers’ L1, and length of residence in the speakers’ country.
