Defective pronunciation of one or more mother language phones, i.e. dyslalia, represents the most frequent speech impairment both in children and adult people. Cases of persisting speech disorder need professional approach and help. The aim of the study was to obtain a model of physiological articulation of the sibilant "s" in children. The method of FFT spectral analysis was made use of. Results will serve for further use in evaluation of speech impairment.

Speech disorders are significant barriers to the balanced development of a child. Many children in Poland are affected by lisps (sigmatism)-the incorrect articulation of sibilants. Since speech therapy diagnostics is complex and multifaceted, developing computer-assisted methods is crucial.

This study explores the influence of lexicality on gradient judgments of Swedish sibilant fricatives by contrasting ratings of initial fricatives in words and word fragments (initial CV-syllables). Visual-Analogue Scale (VAS) judgments were elicited from experienced listeners (speech-language pathologists; SLPs) and inexperienced listeners, and compared with respect to the effects of lexicality using Bayesian mixed-effects beta regression. Overall, SLPs had higher intra- and interrater reliability than inexperienced listeners.

This paper addresses the idiosyncratic cluster simplification patterns observed in a child with disordered phonological development, who is acquiring Greek. The child has mastered word-internal and word-final codas and clusters of reversed sonority. However, the child does not realise the target well-formed tautosyllabic [Obstruent+Liquid] clusters with rising sonority.

Purpose: This study examines whether there are differences in the speech of speakers with dysarthria, speakers with apraxia and healthy speakers in spectral acoustic measures during production of the central-peninsular Spanish alveolar sibilant fricative /s/.
Method: To this end, production of the sibilant was analyzed in 20 subjects with dysarthria, 8 with apraxia of speech and 28 healthy speakers. Participants produced 12 sV(C) words.

Lower Sorbian is a moribund language spoken in Eastern Germany that features a three-way sibilant contrast, /s, ʂ, ɕ/. The vast majority of L1 speakers are above eighty years of age and virtually no young Sorbians learn Lower Sorbian as their first language. There are language revitalization programs in place, but this means that virtually all Lower Sorbian speakers are L2 learners whose first language is German.
