Standardised tests of whole-word accuracy are popular in the speech pathology and developmental psychology literature as measures of children's speech performance. However, they may not be sensitive enough to measure changes in speech output in children with severe and persisting speech difficulties (SPSD). To identify the best ways of doing this,…

This article presents a case study of speech production in a 14-year-old Amharic-speaking boy. The boy had developed secondary macroglossia, related to a disturbance of growth hormones, following a history of normal speech development. Perceptual analysis combined with acoustic analysis and static palatography is used to investigate the specific…

In this article, we discuss the relationship between instrumental and perceptual phonetic analyses. Using data drawn from typical and atypical speech production, we argue that the use of two-tier transcriptions, which can compare and contrast perceptual and instrumental information, is valuable both for our general understanding of the mechanisms…

Foreign accent syndrome (FAS) is an acquired neurologic disorder in which an individual suddenly and unintentionally speaks with an accent which is perceived as being different from his/her usual accent. This study presents an acoustic-phonetic description of two Quebec French-speaking cases. The first speaker presents a perceived accent shift to…

Foreign accent syndrome (FAS) is an acquired neurogenic disorder characterized by altered speech that sounds foreign-accented. This study presents a British subject perceived to speak with an Italian (or Greek) accent after a brainstem (pontine) stroke. Native English listeners rated the strength of foreign accent and impairment they perceived in…

The current investigation examined the development of voice onset time (VOT) in Standard-Greek (SG) and Cypriot-Greek (CG)-speaking children at age levels 2;0-2;5, 2;6-2;11, 3;0-3;5, and 3;6-4;0 years. SG presents with a two-way voicing contrast (voiced and voiceless unaspirated stops) whereas CG is a three-way contrast dialect containing…

This review examines the literature on the use of non-pulmonic egressive sounds in disordered speech. Studies are described that report the use of pulmonic ingressive speech, clicks, ejectives, and implosives. Broad trends are identified linking the use of each type of non-pulmonic-egressive airstream use with particular disorders. The importance…

Patients with cochlear implants have the ability to exercise auditory control over their own speech production and over the speech of others, which is important for the development of speech control. In the present investigation three groups of 10 subjects were compared. The groups comprised: (1) cochlear implant users, (2) profoundly deaf using…

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…

Images of tongue/palate contact for the nasal phoneme /n/ were created using the electropalatograph (EPG). Seven typical Australian adults with no history of hearing or communication difficulty produced syllables containing /n/ paired with five vowels. The majority of productions were symmetrical had contact with the alveolar ridge, and lateral…

Productions of /s/ and /z/ by ten adult speakers were investigated using the electropalatograph (EPG). The participants, ten speech researchers who spoke English as their first language, recorded productions of /s/ and /z/ in nonsense and real words. The maximum contact frame was used as the point of reference to compare tongue/palate contact for…
