The present work begins with a phonetic description of the acceptable French /R/ and descriptions of several allophones of English /R/ which must be avoided while learning the French. Various theories are discussed concerning the relationship between the position of the /R/ in an utterance and the difficulty students have in pronouncing it…

The production of word-initial stop consonants /p t k/ and /b d g/ was investigated in the speech of 37 deaf and six normally hearing adolescents. It is argued here that the deaf child does not simply make errors in speaking, but instead realizes sounds in accordance with a deviant phonological system. (Author/TL)

Allophonic variations in the quality and voicelessness of British English Received Pronunciation /1/ were investigated, largely through their acoustic correlates as revealed by spectrography. (Author/RM)

A sentence-reading procedure was used to study the influence of syntactic structure on the timing of syllables in speech production. The study was designed to test whether syllable lengthening might be sensitive to the distinction between surface and underlying structure. (Author/RM)

Examined the effects of rounded and unrounded vowels on the perception of the voiceless fricatives "s" and "sh" by adults and by young children who could and could not produce both sounds. Concluded that productive mastery is not critically responsible for perception of the distinction between the two phonemes or the…

Misarticulation of consonants in a sample of 384 standard English-speaking children from the first grade through the 12th grade was recorded and classified according to type of error: omission, substitution, or distortion. (Author)

Simultaneous Capacity'' is the number of syllables which can be correctly repeated after having been heard once. (WB)

Two studies investigated how components of speaking rate, articulation rate and pause rate, combine to influence processing of the silence-duration cue for the voicing distinction in medial stop consonants. Listeners adjust for both articulation rate and pause rate changes in articulation rate had more effect on phonetic judgments. (Author/RD)
