Purpose: Phoneme categorization (PC) for voice onset time and second formant transition was studied in adult cochlear implant (CI) users with early-onset deafness and hearing controls. Method: Identification and discrimination tasks were administered to 30 participants implanted before 4 years of age, 21 participants implanted after 7 years of…

Radical advancements in hearing technology in the last 30 years have offered some deaf and hard-of-hearing (DHH) children the adequate auditory access necessary to acquire spoken language with high-quality early intervention. However, meaningful achievement gaps in reading and spoken language persist despite the engineering marvel of modern…

Mastery of the alphabetic principle necessitates learning letter--sound correspondences. In this study, we found evidence of the importance of spoken phonology in the letter--sound learning of 89 deaf or hard-of-hearing (DHH) preschoolers. Only DHH children with at least some ability to perceive speech were included in the study. DHH children were…

This study investigated differences in the phonological knowledge and reading skill of deaf adults using three experimental conditions that tested sensitivity to syllables, rhyme, and phonemes. Analysis of response latencies and accuracy in the three awareness tasks demonstrated that skilled deaf readers had superior phonological awareness skill…

Purpose: Several acoustic cues specify any single phonemic contrast. Nonetheless, adult, native speakers of a language share weighting strategies, showing preferential attention to some properties over others. Cochlear implant (CI) signal processing disrupts the salience of some cues: In general, amplitude structure remains readily available, but…

The objective of this study was to investigate the perceptual relevance of acoustic differences in vowels produced by 6 children between the ages of 9-13 years old with unilateral cochlear implants. Formant frequencies were estimated for 12 repetitions of vowels /hid/, /hed/, /haed/, /hud/, /hUd/, and /hAd/ produced by the children. The estimated…

The goal of this study was to explore the development of spoken phonological awareness for deaf and hard-of-hearing children (DHH) with functional hearing (i.e., the ability to access spoken language through hearing). Teachers explicitly taught five preschoolers the phonological awareness skills of syllable segmentation, initial phoneme isolation,…

This paper reports on a rare phenomenon in language development--the production of words without consonants, and thus syllables without an onset. Such words, which are referred as Consonant-free words (CFWs), appeared for a short period in the early speech of hearing impaired Hebrew-speaking children, who produced words consisting of one or two…

This paper reports on a clinical trial evaluating outcomes of a frequency-lowering technique for adolescents and young adults with severe to profound hearing impairment. Outcomes were defined by changes in aided thresholds, speech perception, and acceptance. The participants comprised seven young people aged between 13 and 25 years. They were…

Locus equations (LEs) were derived from consonant-vowel-consonant (CVC) syllables produced by four speakers with profound hearing loss. Group data indicated that LE functions obtained for the separate CVC productions initiated by /b/, /d/, and /g/ were less well-separated in acoustic space than those obtained from speakers with normal hearing. A…

This study investigated the perception of voice onset time (VOT) in speech produced during simultaneous communication (SC). Four normally hearing, experienced sign language users were recorded under SC and speech alone (SA) conditions speaking stimulus words with voiced and voiceless initial consonants embedded in a sentence. Twelve…

The articles in this paper explore the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical research applications. Titles of the papers and their authors are as follows: (1) "Task Dynamic Coordination of the Speech Articulators: A Preliminary Model" (Elliot Saltzman); (2) "Some Observations…

This study evaluated English phrases and sentences in a minimal-pairs syllable-test format, to assess use of acoustic cues in audiovisual perception of speech by persons with severe or profound hearing loss. Of 48 items, 39 were visually confusable; 16 items identified as visually confusable were reliably identifiable when sound was added.…

This book contains the following articles on research in the field of general linguistics and sociolinguistics: "Papago Plurals" (Jane H. Hill, Ofella Zepeda); "Typological Characteristics of the Yumanas Languages" (Mauricio J. Mixco); "Observations on Accent in Yutoaztec" (Leopoldo Valinas); "Development of…
