This dissertation investigates how the abstract representation of vowels affects spoken word recognition in Brazilian Portuguese and American English by examining two issues in theoretical phonology and speech processing: underspecification theory, and underlying representation when there is alternation. Three experiments were conducted in…

Purpose: Place and manner of articulation in American English-learning children's salient consonant-vowel-consonant-vowel (C[subscript 1]VC[subscript 2]V) target words (e.g., "baby," "bunny," and "cookie") were compared with their actual productions of these words. We hypothesized that target words with repeated place…

While voicing contrasts in word-onset position are acquired relatively early, much less is known about how and when they are acquired in word-coda position, where accurate production of these contrasts is also critical for distinguishing words (e.g., dog vs. dock). This study examined how the acoustic cues to coda voicing contrasts are realized in…

Programs for teaching English reading, especially for students with dyslexia, and educational practice standards often recommend instruction on dividing polysyllabic words into syllables. Syllable division is effort intensive and could inhibit fluency when reading in text. The division strategies might still be useful if they work so consistently…

Purpose: The aim of the study was to examine associations between speaking fundamental frequency (f[subscript os]), vowel formant frequencies (F), listener perceptions of speaker gender, and vocal femininity-masculinity. Method: An exploratory study was undertaken to examine associations between f[subscript os], F[subscript 1]-F[subscript 3],…

Previous studies on second language (L2) phonetic acquisition in early bilingual learners have mainly examined immigrants to the L2 country; however, with recent growing dual-language immersion programs, the immersed bilingual group emerged and required more attention in the research. This study aims to investigate vowel patterns of young…

Infant-directed speech (IDS) is phonetically distinct from adult-directed speech (ADS): It is typically considered to have special prosody--like higher pitch and slower speaking rates--as well as unique speech sound properties, for example, more breathy, hyperarticulated, and/or variable consonant and vowel articulation. These phonetic features…

Korean learners of English are known to repair consonant clusters, which are not allowed in their native language, with an epenthetic vowel [close central unrounded vowel]. The purpose of the present study is to examine whether the perception-production link of such an illusory vowel in a second language (L2) is only within and not across…

Learning to read in most alphabetic orthographies requires not only the acquisition of simple grapheme-phoneme correspondences (GPCs) but also the acquisition of context-sensitive GPCs, where surrounding letters change a grapheme's pronunciation. We aimed to explore the use and development of simple GPCs (e.g. a [right arrow] /ae/) and…

Feature-based approaches to acquisition principally focus on second language (L2) learners' ability to perceive non-native consonants when the features required are either contrastively present or entirely absent from the first language (L1) grammar. As features may function contrastively or allophonically in the consonant and/or vowel systems of…

Classroom time is limited, so the priority question in teaching pronunciation is to find an effective sequence of presentation. This article recounts one teacher's path to learning about different approaches to teaching English rhythm and why it is important. For many years, a common way of distinguishing languages has been based on the assumption…

During spoken word processing, native (L1) listeners use allophonic variation to predictively rule out word competitors and speed up word recognition. There is some evidence that second language (L2) learners develop an awareness of allophonic distributions in their L2, but whether they use their knowledge to facilitate word recognition online,…

In traditional, generative phonology, sound patterns are represented in terms of abstract features, typically based on the articulatory properties of the sounds. The present study makes use of an artificial language learning experiment to explore when and how learners extend a novel phonological pattern to novel segments. Adult, English-speaking…

The spelling of an English word may reflect its part of speech, not just the sounds within it. In 2 preregistered experiments, we asked whether university students are sensitive to 1 effect of part of speech that has been observed by linguists: that content words (e.g., the noun "inn") must be spelled with at least 3 letters, whereas…

Although extensive research has focused on the perceptual abilities of second language (L2) learners, a significant gap persists in understanding how cognitive functions like phonological short-term memory (PSTM) and nonverbal intelligence (IQ) impact L2 speech perception. This study sets out to investigate the discrimination of L2 English…
