Using electopalatography, this study investigated the production of sibilants produced by four adults who have severe-to-profound hearing loss and four speakers with normal hearing. Each speaker wore a Rion[R] semi-flexible electroplate while producing multiple repetitions of the utterances "see, sue, she, shoe." The speakers' productions were…

Two experiments used a magnitude estimation paradigm to test whether perception of disfluency is a function of whether the speaker and the listener stutter or do not stutter. Utterances produced by people who stutter were judged as "less fluent," and, critically, this held for apparently fluent utterances as well as for utterances…

Phonotactic probability, a measure of the likelihood of occurrence of a sound sequence, appears to facilitate noun learning (H. L. Storkel, 2001). Nouns and verbs, however, tend to differ in rate of acquisition, indicating that word-learning mechanisms may differ across grammatical class. The purpose of the current study was to examine the effect…

Most studies have been unable to identify reliable acoustic cues for the recognition of the English nonsibilant fricatives /f, v, [theta], [eth]/. The present study was designed to test the extent to which the perception of these fricatives by normal-hearing adults is based on other sources of information, namely, linguistic context and visual…

This paper describes research investigating the perception of intrusive music, that is, music heard when choice, volume, and occurrence are not under the control of the participant. Participants were directed to record diary accounts of episodes in which music was played in instances when they were not in control of the decision to play the music…

Recent work suggests that once the auditory cortex of deaf persons has been reorganized by cross-modal plasticity, it can no longer respond to signals from a cochlear implant (CI) installed subsequently. To further examine this issue, we compared the evoked potentials involved in the processing of visual stimuli between CI users and hearing…

We investigated the effect of legato and staccato articulation styles on the perception of modulated tempos. Ninety music majors served as participants. Listeners heard music examples that had been selected from two pieces, each of which included staccato and legato passages. Excerpts were presented to listeners in three conditions of tempo…

Purpose: In this study, the authors aimed to develop a visual analogue of the widely used Speech Reception Threshold (SRT; R. Plomp & A. M. Mimpen, 1979b) test. The Text Reception Threshold (TRT) test, in which visually presented sentences are masked by a bar pattern, enables the quantification of modality-aspecific variance in speech-in-noise…

The study investigated adaptation to a standard electropalatographic (EPG) practise palate in a group of eight adults (mean age = 24 years). The participants read the phrase "a CVC" over four sampling conditions: prior to inserting the palate, immediately following insertion of the palate, 45 minutes after palate insertion, and 3 hours after…

A popular theoretical account of developmental language and literacy disorders implicates poor auditory temporal processing in their etiology, but evidence from studies using behavioral measures has yielded inconsistent results. The mismatch negativity (MMN) component of the auditory event-related potential has been recommended as an alternative,…

Purpose: Investigate training-related changes in acoustic-phonetic representation of consonants produced by a text-to-speech (TTS) computer speech synthesizer. Method: Forty-eight adult listeners were trained to better recognize words produced by a TTS system. Nine additional untrained participants served as controls. Before and after training,…

A study employed computational and experimental methods to address a number of issues related to the representation and structural organization of spoken words in the mental lexicon. Using a computerized lexicon consisting of phonetic transcriptions of 20,000 words, "similarity neighborhoods" for each of the transcriptions were computed.…

Results of a verbal sound and meaning discrimination test to check the hypothesis of Alajouanine et al.--that two types of paraphasics can be distinguished, phonemic and semantic--are discussed. The former are impaired in tests of auditory language discrimination, the latter show regression of the semantic values apparent in their linguistic…

Considering Jakobson's theory that speech disorders involve defects in paradigmatic or in syntagmatic operations, and that these two categories result in different defects, this question was examined: does the syntagmatic group suffer from defects not only in contextual generation of active speech but also in comprehension of grammatical…
