Purpose: One of the central questions in speech production research is to what degree certain structures have an inherent difficulty and to what degree repeated encounter and practice make them easier to process. The goal of this article was to determine the extent to which frequency and sonority distance of consonant clusters predict production…

This investigation explored the voice onset time (VOT) values of word-initial bilabial stops /p/ and /b/ as realized by Arabic-speaking male and female Saudi ESL learners. It sought to identify the differences, if any, between these two groups with regard to this acoustic measure (i.e., VOT). The VOT measurements were then compared with those of…

The Perceptual Assimilation Model (PAM) (Best, 1995) claims listeners directly perceive articulatory gestures of the vocal tract rather than acoustic/auditory signals. Accordingly, the articulatory similarities and discrepancies between native and non-native sounds determine the perceptual assimilation patterns of non-native sounds. This study…

Common descriptions of articulatory requirements for production of the alveolar trill /r/ mainly focus on describing the configuration of the anterior portions of the tongue, while in contrast, the more posterior parts receive limited attention. Understanding how the posterior portions of the tongue move is vital for understanding speech motor…

This study examined Korean learners' production of intervocalic English biconsonantal clusters consisting of /p/, /t/, /k/, /m/, /n/, or /[eng] / followed by /l/ or /[voiced alveolar approximant]/. The results of the production experiment showed several factors influencing Korean learners' production. First, Korean learners' production was…

Purpose: Words, syllables, and phonemes have each been regarded as basic encoding units of speech production in various psycholinguistic models. The present article investigates the role of each unit in the interface with speech articulation, using a paradigm from motor control research. Method: Seventy-six native speakers of French were trained…

The study aims to investigate guttural and emphatic sounds and the phenomenon of emphasis spread in Fallaahi Jordanian Arabic (FJA), a rural Jordanian dialect spoken in the north of Jordan. The study uses a non-linear approach, namely, the feature geometry approach to represent guttural and emphatic sounds and the phenomenon of emphasis spread.…

Understanding how native speakers acquire the phonological patterns in their language is a key task for the field of phonology. Numerous studies have suggested that phonological learning is a biased process: certain phonological patterns are easily accessed and learned by the speakers, while others show acquisition difficulties. These differences…

Purpose: The purpose of this study was to investigate the psychophysical boundary used for categorization of voiced-voiceless stop consonants in native Japanese speakers. Method: Twelve native Japanese speakers participated in the experiment. The stimuli were synthetic stop consonant-vowel stimuli varying in voice onset time (VOT) with…

The study shows that there are two distinct lateral phonemes in Turkish with a minimal pair example. 20 male native speakers of Turkish, aged 20-26, were asked to read six short phrases and a minimal pair which contained laterals. The spectrograms were examined by PRAAT to determine whether it is possible to identify the laterals with regard to…

This dissertation investigates Voice Onset Time (VOT), which serves as an essential property for differentiating plosive consonants in L1 and L2 Mandarin Chinese. It surveys VOT variations and demonstrates that they are affected by several phonetic and phonological properties, e.g., lexical tone, place of articulation (POA), speech rate,…

Instruction in second language (L2) English phoneme pronunciation almost invariably includes a focus on improving the learners' use of their articulatory organs to pronounce the relevant sounds. However, the pronunciation of many English sounds also relies on effort from the abdominal region, and under-utilization of this region can often…

A fundamental issue in speech science concerns the extent to which speech sounds are mentally represented by articulatory-motor and/or auditory-acoustic features. This dissertation aims to expand upon the current literature by investigating changes in production and perception following visual feedback training with either articulatory or acoustic…

Coarticulation data for Catalan reveal that, while being less sensitive to vowel effects at the consonant period, the alveolar trill [r] exerts more prominent effects than [dark "l"] on both adjacent [a] and [i]. This coarticulatory pattern may be related to strict manner demands on the production of the trill. Both consonants also differ…

The present article reports on the findings of a cross-sectional acoustic study of the production of the Spanish /e/-/ei/ contrast, as in "pena-peina" and "reno-reino," by native-English intermediate and advanced learners of Spanish. The acoustic parameter that distinguishes Spanish /e/ from /ei/ is formant change--/e/ is a…
