Research has found that speaking rate has an effect on voice onset time (VOT). Given that Parkinson disease (PD) affects speaking rate, the purpose of this study was to examine VOT with the effect of rate removed (VOT ratio), along with the traditional VOT measure, in individuals with PD. VOT and VOT ratio were examined in 9 individuals with PD…

The specific mechanisms that underlie childhood stuttering are not fully understood. The current study investigated these mechanisms by comparing the effect on fluency of priming different components of a short sentence. The main findings were that: (1) both children who stutter (CWS) (n = 12, M age = 6;3) and children who do not stutter (CWNS) (n…

We identified individuals with deficits in musical pitch recognition by screening a large random population using the Distorted Tunes Test (DTT), and enrolled individuals who had DTT scores in the lowest 10th percentile, classified as tune deaf. We examined phonological processing abilities in 35 tune deaf and 34 normal control individuals. Eight…

A significant number of bilinguals in English-speaking countries speak Korean as their first language. One such country is the United States (U.S.). As the U.S. becomes increasingly diverse, providing more effective services for culturally and linguistically diverse children is a critical issue and growing challenge for speech-language…

Describes the major types of acoustic analysis available for the study of speech, identifies equipment and other components needed for a modern speech-analysis laboratory, and lists possible measurements for various aspects of phonation, articulation, and resonance, as they might be seen in neurologically disordered speech. (Author/DB)

This study examined interjudge agreement levels for five adult listeners assessing either overt stuttering or disfluency types in the spontaneous speech of eight young children. Results showed that the interjudge reliability for judgments based on a disfluency taxonomy was not significantly different from that based on stuttering. The importance…

Discussion of how functional neuroimaging has been applied to the study of speech production first reviews neuroimaging methods and limitations, then describes two approaches to study of the relevant speech areas: comparison across different language production tasks and comparison of effects of different stimuli within a single task. Examples…

This article addresses the rationale for and issues related to the use of speech appliances, especially a removable speech appliance that positions the tongue to produce the correct /r/ phoneme. Research results suggest that this appliance was successful with a large group of clients. (Author/DB)

Three children with developmental apraxia of speech (DAS) identified syllables in words, judged intrasyllabic sound positions, and constructed syllable shapes within monosyllabic frames. Results suggest that DAS children demonstrate an apparent breakdown in the ability to perceive "syllableness" and to access and compare syllable…

This study compared two methods of speech elicitation for phonological assessment: conversation and picture naming with 13 male phonologically impaired children (ages 4.2 to 5.11 years). Results suggest that both methods are useful clinical assessment tools but that the picture-naming test may tap the child's phonological system more deeply and be…

This study compared phonological patterns in the speech of 25 children prenatally exposed to cocaine and multiple drugs and with 25 non-exposed children (all children ages 22 to 51 months). Prenatal exposure to drugs was associated with an increase in the use of phonological processes. Results suggest that these children's speech development is…

This study evaluated an experimental articulation testing instrument for differentiating child speakers (N=21, ages 5:0 to 6:6) of African-American Vernacular English (AAVE) with atypical and typical phonologies. Significant group differences were observed, suggesting that the measure can differentiate typical and atypical development in this…

This article describes an approach to the treatment of young children whose speech problems are classified in the category of "persistent sound system disorder." The approach fosters development of stimulability skills through broadening of the phonetic inventory early in the treatment process. A case study illustrates treatment…

This study examined the speech of 54 young Spanish-speaking (Puerto Rican dialect) children with phonological disorders. It described the mean percentage-of-occurrence and standard deviation of phonological processes and the number and type of nontargeted process errors. Specific patterns characterizing the speech of these children were…

A survey of 1,184 speech language pathologists found that of 2,628 children (grades 1-12) who stuttered, 62.6% had other concurring speech disorders, language disorders, or non-speech-language disorders. Articulation disorders (33.5%) and phonology disorders (12.7%) were the most frequently reported. Males were more likely to exhibit co-occurring…
