A description of an electromyographic investigation carried out on the speech of deaf speakers. The research attempted to answer questions concerning articulation and phonetic patterns in the speech of deaf adults. Results indicated that the deaf speakers extended the duration of speech segments and exhibited difficulty coordinating articulation…

A study analyzed the effects of a masking condition on the speech production of three cerebral palsied adults, specifically on speech duration, extraneous vocal behavior, and articulation. (AM)

The magnitudes and patterns of two-point difference limens (DL) of the tongue were studied in children with and without articulation errors. Many children with misarticulation of /r/ had DLs that differed in magnitude and pattern from those of children with normal articulation and those with misarticulations of /s/. (NCR)

This is a report on an investigation of the correct production of /s/ in spontaneous speech of children. A greater incidence of incorrect production was found for pre-boundary /s/ than for /s/ in other lexical positions. Lexical position is related to articulatory inconsistencies in child speech. (SC)
