San Felipe Jalapa de Díaz (Jalapa) Mazatec is unusual in possessing a three-way phonation contrast and level tone independent of phonation. This study investigates the acoustics how interact this language, such interactions are maintained across variables like speaker sex, vowel timecourse, presence aspiration onset. Using large number words from recordings made by Paul Kirk Peter Ladefoged 1980s 1990s, results our acoustic statistical analysis support claim that spectral measures H1-H2...

Abstract The term sonority projection refers to behavioural distinctions speakers make between unattested phonological sequences on the basis of sonority. For example, among onset clusters, well-formedness relation [bn]>[lb] is observed in speech perception, production and non-word acceptability (Davidson 2006, 2007, Berent et al. Albright, ms). We begin by replicating effects a study. Then we evaluate extent which predicted existing computational models phonotactics (Coleman &...

Previous work demonstrates that a word's status as morphologically-simple or complex may be reflected in its phonetic realisation. One possible source for these effects is paradigm uniformity, which an intended realisation influenced by morphological relatives. For example, the of inflected word frees should phonological plan free, and thus non-homophonous with freeze. We test this prediction analysing productions forty such inflected/simple pairs, embedded pseudo-conversational speech...

At present, two important questions about voice remain unanswered: When quality changes, what physiological alteration caused this change, and if a change to the production system occurs, in perceived can be expected? We argue that these only answered by an integrated model of linking perception, we describe steps towards development such model. Preliminary evidence support approach is also presented. conclude should priority for scientists interested voice, explain physical condition(s)...

This study investigates the importance of source spectrum slopes in perception phonation by White Hmong listeners. In Hmong, nonmodal (breathy or creaky voice) accompanies certain lexical tones, but its tonal contrasts is unclear. this study, native listeners participated two perceptual tasks, which they were asked to identify word heard. first task, participants heard natural stimuli with manipulated F0 and duration (phonation unchanged). Results indicate that important identifying breathy...

The question of what type utterance-a sustained vowel or continuous speech-is best for voice quality analysis has been extensively studied but with equivocal results. This study examines whether previously reported differences derive from the articulatory and prosodic factors occurring in speech versus phonation.Speakers disorders vowels read sentences. Vowel samples were excerpted steadiest portion each In addition to vowels, a 3rd set stimuli was created by shortening productions match...

American English has several linguistic sources of creaky voice. Two common are /t/-glottalization (where /t/ is produced as a glottal stop and/or with voice, in “button”) and phrase-final creak. Both creak have similar acoustic properties, but they can co-occur English. The goal this study to determine whether perceived distinctly. Sixteen listeners were asked identify words two-alternative forced choice task. auditory targets (near-) minimal pairs, which one word could (e.g., the other not...

A psychoacoustic model of the voice source spectrum is proposed. The characterized by four spectral slope parameters: difference in amplitude between first two harmonics (H1–H2), second and fourth (H2–H4), harmonic nearest 2 kHz frequency (H4–2 kHz), that 5 (2 kHz–5 kHz). As a step toward validation, experiments were conducted to establish acoustic perceptual independence these parameters. In experiment 1, was fit large number sources. Results showed parameters are predictable from one...

At present, it is not well understood how changes in vocal fold biomechanics correspond to voice quality. Understanding such cross-domain links from physiology acoustics perception the “speech chain” of both theoretical and clinical importance. This study investigates between body layer stiffness, which regulated primarily by thyroarytenoid muscle, consequent quality under left-right symmetric asymmetric stiffness conditions. Voice samples were generated using three series two-layer physical...

No agreed-upon method currently exists for objective measurement of perceived voice quality. This paper describes validation a psychoacoustic model designed to fill this gap. includes parameters characterize the harmonic and inharmonic sources, vocal tract transfer function, fundamental frequency, amplitude voice, which together serve completely quantify integral sound target sample. In experiment 1, 200 voices with without diagnosed pathology were fit using analysis-by-synthesis. The...

Many languages use phonation types for phonemic or allophonic distinctions. This study examines the acoustic structure of phonetic space vowel phonations across languages. Our sample eleven includes with contrastive modal, breathy, creaky, lax, tense, harsh, and/or pharyngealized phonations, and nonmodal on particular tones. In compiling analyzing this we address related issues such as contrast vs. allophony, similarity languages, understanding complex contrasts several multidimensional...

In this study, we determine the acoustic correlates of primary and secondary stress in Tongan. Vowels with show differences f0, intensity, duration, F1, spectral measures compared to unstressed vowels, but a linear discriminant analysis suggests f0 duration are best cues for discriminating vowels from vowels. mainly marked by relative With regard effects on vowel space, find that all five Tongan higher space (have lower F1) when unstressed. Moreover, there is no reduction overall size space....

Abstract Phonation types, or contrastive voice qualities, are minimally produced using complex movements of the vocal folds, but may additionally involve constriction in supraglottal and pharyngeal cavities. These articulations turn produce a multidimensional acoustic output that can be modeled various ways. In this study, I investigate whether psychoacoustic model by Kreiman et al. (2014) succeeds at distinguishing six phonation types !Xóõ. Linear discriminant analysis is performed...

<p class="p1">In American English, voiceless codas /t/ and /p/ are often glottalized: They have glottal constriction that results in creaky voice on the preceding vowel. Previous claims suggest such glottalization can serve to enhance or, more generally, voicelessness of coda stops. In this study, we examine timecourse word recognition test whether facilitates perception words ending /p/, which is expected if fact enhancing. Sixty English listeners participated an eye-tracking where they...

Variation in voicing is common among sounds of the world’s languages: that are analyzed as voiceless can undergo voicing, and those voiced devoice. Among glottal particular, widespread: linguists often expect stop [ʔ] fricative [h] to be fully voiced, especially between vowels. In this study, we use audio recordings from Illustrations International Phonetic Alphabet published Journal Association explore extent which consonants non-modal (breathy creaky) vowels differ terms percentage...
