The study compared frequency and type of articulation error, including error migration, between single word production and connected speech samples when vocabulary was held constant with 20 articulation disordered children (ages 5-12 years). There were significantly more errors in connected speech samples than in single word utterances. (Author/DB)

Manipulation of speed of delivery and linguistic context followed by factor analysis of 11 measures of lingual activity involved in the production of the syllable /ka/ indicated three factors explained 75 percent of the variance: displacement/velocity, duration, and midsyllable duration and distance.

This paper argues against definitions of stuttering which imply that all within-word disfluencies are stuttering and no between-word disfluencies are stuttering. The paper calls for a definition of stuttering that is not contradicted by available empirical information or clinical experience and is logically consistent. (JDD)

Analysis of the liquid, fricative, and affricate sounds in the phonological system of a misarticulating four year old found that the child's perception of certain sounds was superior to his productions, whereas for other sounds productive skill was superior to perceptual performance. A two-lexicon model of underlying representation best accounted…

This paper examines the need for a transcription system that allows the symbolization of nonnormal articulations. The paper then describes transcription systems proposed by clinical phoneticians and speech pathologists, especially PRDS (phonetic representation of disordered speech) symbols and extensions of the International Phonetic Alphabet.…

The study investigated effects of contrastive stress and phonetic context on misarticulations of consonantal /r/ with nine young children who misarticulated the consonant. Significant main effects were obtained for context and stress. Results are discussed in terms of possible effects of production and perceptual variables on listener judgments.…

The study was conducted to obtain information on test-retest differences in Articulation Indices (AI) when a clinical threshold-based method is used to calculate AI. Standard deviations were greatest when the AI was near 50 percent and were also dependent on the relationship of the hearing thresholds and speech spectrum. (Author/DB)

This investigation compared the effects of single word and connected speech sampling conditions on the production of consonant clusters in 40 children (ages 3-5) with speech sound impairments. Differences between the sampling conditions were apparent for 3 of the 8 phonological processes studied and 1 of 12 phonetic variations. (Author/DB)

Six functionally misarticulating preschool children were taught to produce [r] and one other sound absent from their phonetic inventory. For 86 percent of the 28 monitored sounds, generalization was consistent with pretreatment stimulability skills; production of stimulable sounds tended to improve regardless of whether treatment target was a…

This study investigated effect of production time on the perception of disordered nasalization in 20 children (ages 6-18) with cleft palate. Ten judges used direct magnitude estimates to rate severity of disordered nasalization. Results indicated that reducing the production time did not change perceptible nasalization. (Author/DB)

The study examined the relationship between 28 segmental and suprasegmental acoustic parameters of speech production and measures of speech intelligibility for 40 severely to profoundly hearing-impaired persons (mean age 21 years). Findings support the tractability of employing selected acoustic variables for the estimation of speech…

This study of 21 children (ages 4-6) found that children with stuttering and disordered phonology produced more sound prolongations and fewer iterations per whole-word repetition than did children who stuttered but had normal phonology. No differences were noted between children with stuttering and disordered phonology and children with disordered…

Analysis of data from eight adult cochlear implant users found that improvements in their production and perception of a given vowel contrast and normally hearing listeners' identification of that contrast tended to occur together. Results support the view that restoring self-hearing allows a speaker to adjust articulatory routines to ensure…

This study investigated the effect of the administration of frequent and infrequent probe lists on generalization with four articulation disordered children (ages 3:10 to 5:8). Results indicated that frequency of probe list administration did not produce any predictable effect on the extent of generalization or the occurrence of a practice effect.…

Three studies of phonological knowledge and generalization were conducted with six functionally misarticulating children, aged 3-4. Results indicated that productive phonological knowledge of the sound system influenced the amount of generalization learning. The extent of generalization learning was associated with the point on the knowledge…
