TL;DR: The spreading of the vocal folds that occurs during unvoiced stops in certain contexts in English is an enhancing gesture, which aids the resolution of the gestural conflict by allowing the defining segmental gesture to be weakened without losing perceptual salience.
Abstract: When a vowel follows an obstruent, the fundamental frequency in the first few tens of milliseconds of the vowel is known to be influenced by the voicing characteristics of the consonant. This influence was re-examined in the study reported here. Stops, fricatives, and the nasal /m/ were paired with the vowels /i,ɑ/ to form CVm syllables. Target syllables were embedded in carrier sentences, and intonation was varied to produce each syllable in either a high, low, or neutral pitch environment. In a high-pitch environment, F0 following voiceless obstruents is significantly increased relative to the baseline /m/, but following voiced obstruents it closely traces the baseline. In a low-pitch environment, F0 is very slightly increased following all obstruents, voiced and unvoiced. It is suggested that for certain pitch environments a conflict can occur between gestures corresponding to the segmental feature [stiff vocal folds] and intonational elements. The results are different acoustic manifestations of [stiff] in different pitch environments. The spreading of the vocal folds that occurs during unvoiced stops in certain contexts in English is an enhancing gesture, which aids the resolution of the gestural conflict by allowing the defining segmental gesture to be weakened without losing perceptual salience.

TL;DR: Four experiments addressing the role of attention in phonetic perception indicate that careful attention to speech perception is necessary for strong acoustic cues to achieve their full impact on phonetic labeling, while weaker acoustic cues (FO onset frequency and vowel duration) achieve theirFull impact on speech perception without close attention.

TL;DR: In this paper, Slowiaczek and Dinnsensenior presented an experiment based on materials recorded in a situation approaching spontaneous dialogue and involving monolingual speakers of one variety of Standard Polish and found that neither perceptual tests nor measurements of segmental duration gave any grounds for rejecting [voice] neutralization either in phrase-final devoicing or in internal assimilation.

TL;DR: In this article, a case study of a child acquiring English and Spanish in England between the ages of 1;7 and 2;3 is presented, where VOT measurements of utterance-initial stops were made of productions at ages 1,7, 1;11, and 2,3.

TL;DR: The articulation errors of 32 spastic and 18 athetoid males, aged 17-55 years, were analyzed using a confusion matrix paradigm and it was found that within- manner errors exceeded between-manner errors by a substantial amount.
Abstract: The articulation errors of 32 spastic and 18 athetoid males, aged 17-55 years, were analyzed using a confusion matrix paradigm. The subjects had a diagnosis of congenital cerebral palsy, and adequate intelligence, hearing, and ability to perform the speech task. Phonetic transcriptions were made of single-word utterances which contained 49 selected phonemes: 22 word-initial consonants, 18 word-final consonants and nine vowels. Errors of substitution, omission and distortion were categorized on confusion matrices such that patterns could be observed. It was found that within-manner errors (place or voicing errors or both) exceeded between-manner errors by a substantial amount, more so on final consonants. The predominant within-manner errors occurred on fricative phonemes for both initial and final positions. Affricate within-manner errors, all of devoicing, were also frequent in final position. The predominant between-manner initial position errors involved liquid-to-glide and affricate-to-stop changes, and for final position, affricate-to-fricative. Phoneme omission occurred three times more frequently on final than on initial consonants. The error data of individual subjects were found to correspond with the identified overall group patterns. Those with markedly reduced speech intelligibility demonstrated the same patterns of error as the overall group. The implications for treatment are discussed.
