Research on the acoustic characteristics of Infant Directed Speech (IDS) in North American English indicates that it is generally higher-pitched than Adult Directed Speech (ADS) and has unique prosodic characteristics, which is commonly found across many spoken languages. However, very little research has addressed another important aspect of…

Segmentation is a cornerstone of language processing across levels of linguistic analysis, and yet, standard models of linguistic memory leave the role of higher-order segments in online comprehension understudied. This dissertation advances the Context-Sensitive Encoding (CSE) hypothesis: that implicit prosodic boundaries (Bader, 1998; J. Fodor,…

Background: Previous research has shown that syllables are important units in visual word recognition in Spanish. If they are treated as real phonological units, then other related phonological features such as lexical stress (syllable prominence) may also play a role in this process. At times, lexical stress is the only difference between minimal…

Cross-linguistic influence has been observed across all domains of language. However, nothing is known about the role of cross-linguistic influence in bilingual speakers' use of vocal fry. Several recent studies have identified an upsurge in the use of vocal fry among female speakers of American English. We sought to identify cross-linguistic…

Background: The expressiveness during reading is essential for a fluent reading. Reading prosody has been scarcely studied in an experimental manner, owing to the difficulties in taking objective and direct measures of this reading skill. However, new technologies development has made it possible to analyse reading prosody in an experimental way.…

This dissertation deals with the perception of the aspirated coda /s/ by Spanish L2 learners. Second language research, with some exceptions, focuses on whether L1English-L2 Spanish learners can perceive the aspirated variant, showing that only advanced learners with time spent in s-weakening regions succeed at the task. L2 studies about…

Background: Individuals with affective-prosodic deficits have difficulty understanding or expressing emotions and attitudes through prosody. Affective prosody disorders can occur in multiple neurological conditions, but the limited knowledge about the clinical groups prone to deficits complicates their identification in clinical settings.…

Purpose: The aim of this study was to investigate infants' listening preference for emotional prosodies in spoken words and identify their acoustic correlates. Method: Forty-six 3- to-12-month-old infants (M[subscript age] = 7.6 months) completed a central fixation (or look-to-listen) paradigm in which four emotional prosodies (happy, sad, angry,…

This dissertation is about implicit prosody, the prosodic structure that readers assign during silent reading. The dissertation has several goals: determining which reading tasks are appropriate for studying implicit prosody, establishing how grammatical principles could guide incremental assignment of prosodic structure, and investigating how…

Purpose: The purpose of the present study was to examine whether there is a listening preference for child-directed speech (CDS) over backward speech in moderate-preterm infants (MPIs). Method: Eighteen MPIs of gestational age of 32.0 weeks (range: 32-34.06 weeks), chronological age of 8.09 months, and maturation age of 6.48 months served as the…

This conversation analytic study offers an empirical analysis of the Japanese turn-initial interjection "are." The interjectional "are" is said to be pragmatized from its use as a distal demonstrative and has been considered as an expression of a speaker's internal state of being surprised at something. In contrast, this study…

Background: Maternal input plays an important role in influencing linguistic development during the first years of life, and it is evident that mothers adapt their language according to their child's characteristics. Recently, it was demonstrated that maternal input addressed to children with sex chromosome trisomies (SCTs) at 8 months of age is…

In this dissertation, I investigate how people navigate ambiguity in everyday speech, with a focus on quantifier-negation sentences. Combining corpus analysis, behavioral experiments, and computational modeling in the Rational Speech Act framework, I explore preferred interpretations of quantifier-negation and examine the contexts and prosodies…

Research on second language (L2) pronunciation self-assessment reports a general misalignment between self- and other-assessment. This has been attributed to the object of self-assessment, the self-assessment task, the measures to which self-assessment is compared, and speakers' characteristics. Here, we examined self-assessment of a discrete…

This article describes a simple method to teach pitch, a feature common to both word stress and intonation. The technique can be used by native and nonnative English-speaking teachers and is applicable to students of different levels and language backgrounds. Pronounced as /m/, "mmm" is a sound that should be easy for speakers of any…
