IUPAP and the Interwar World of Science Open
Like the other disciplinary unions that were established after the Great War, the International Union of Pure and Applied Physics (IUPAP) bore the stamp of the punitive attitudes of the Allied nations towards the defeated Central Powers. F…

Introduction to the special issue on perception and production of sounds in the high-frequency range of human speech Open
The frequency range audible to humans can extend from 20 Hz to 20 kHz, but only a portion of this range—the lower end up to 8 kHz—has been systematically explored because extended high-frequency (EHF) information above this low range has b…

Dialect and gender perception in relation to the intelligibility of low-pass and high-pass filtered spontaneous speech Open
Most cues to speech intelligibility are within a narrow frequency range, with its upper limit not exceeding 4 kHz. It is still unclear whether speaker-related (indexical) information is available past this limit or how speaker characterist…

Structured covariation of acoustic cues to coda voicing throughout the syllable Open
In English, multiple acoustic cues signal the voiced-voiceless distinction in stop codas. The strongest cue to this contrast is preceding vowel duration: voiced codas tend to be associated with longer vowels and voiceless codas with shorte…

Variability in within-category implementation of stop consonant voicing in American English-speaking children Open
The development of stop consonant voicing in English-speaking children has been documented as a progressive mastery of phonological contrast, but implementation of voicing within one voicing category has not been systematically examined. T…

Perception of local and non-local vowels by adults and children in the South Open
This study assessed the ability of Southern listeners to accommodate extensive talker variability in identifying vowels in their local Appalachian community in the context of sound change. Building on prior work, the current experiment tar…

Summary of “Reintroducing the High-frequency Region to Speech Perception Research” Special Session Open
This paper summarizes a special session entitled "Reintroducing the high-frequency region to speech perception research" presented during the 179th Meeting of the Acoustical Society of America. The three-part session was co-sponsored by th…

Effects of dialect and age on the production of voiced stop closures in running speech Open
Sociophonetic literature investigating consonantal variation in American English has revealed that the production of voiced stop closures in the intersonorant position differs systematically by region. This indicates that sociocultural fac…

Dynamic auditory representations and phonetic processing: The case of virtual diphthongs Open
Auditory spectral integration in the perception of dynamic acoustic cues in speech was examined experimentally. The potential role of a dynamically changing center of gravity in the perception of diphthongs /ui / (as in we) and /iu / (as n…

The old, the new, and the in‐between: Preadolescents’ use of stylistic variation in speech in projecting their own identity in a culturally changing environment Open
Cultural learning begins early, with infants’ and young children's initial imitations of group‐specific local behaviors. Comparatively little is known about cultural development in older children, whose more advanced socio‐cognitive skills…

Reconceptualizing the vowel space in analyzing regional dialect variation and sound change in American English Open
Vowel space area (VSA) calculated on the basis of corner vowels has emerged as a metric for the study of regional variation, speech intelligibility and speech development. This paper gives an evaluation of the basic assumptions underlying …

Dyslexia Limits the Ability to Categorize Talker Dialect Open
Purpose The purpose of this study was to determine whether the underlying phonological impairment in dyslexia is associated with a deficit in categorizing regional dialects. Method Twenty adults with dyslexia, 20 school-age children with d…

Stylistic variation in children’s vowel production Open
The monophthongization of the diphthong [ai] to [a] is possibly the most stereotyped feature of Southern American English. This feature can be observed to varying degrees across the American South. Although monophthongization represents an…

Acoustic properties of vowel production in prelingually deafened Mandarin-speaking children with cochlear implants Open
The present study examined the acoustic features of vowel production in Mandarin-speaking children with cochlear implants (CIs). The subjects included 14 native Mandarin-speaking, prelingually deafened children with CIs (2.9–8.3 yr old) an…

Intrinsic fundamental frequency of vowels is moderated by regional dialect Open
There has been a long-standing debate whether the intrinsic fundamental frequency (IF0) of vowels is an automatic consequence of articulation or whether it is independently controlled by speakers to perceptually enhance vowel contrasts alo…

Variation in Vowel Duration Among Southern African American English Speakers Open
Purpose Atypical duration of speech segments can signal a speech disorder. In this study, we examined variation in vowel duration in African American English (AAE) relative to White American English (WAE) speakers living in the same dialec…
