Speech air flow with and without face masks
(Springer Science and Business Media LLC, 2022)Face masks slow exhaled air flow and sequester exhaled particles. There are many types of face masks on the market today, each having widely varying fits, filtering, and air redirection characteristics. While particle ... -
Gait change in tongue movement
(Springer Science and Business Media LLC, 2021)During locomotion, humans switch gaits from walking to running, and horses from walking to trotting to cantering to galloping, as they increase their movement rate. It is unknown whether gait change leading to a wider ... -
Characteristics of air puffs produced in English 'pa': Experiments and simulations
(Acoustical Society of America (ASA), 2009)Three dimensional large eddy simulations, microphone "pop" measurements, and high-speed videos of the airflow and lip opening associated with the syllable "pa" are presented. In the simulations, the mouth is represented ... -
Biomechanical modeling of English /r/ variants
(Acoustical Society of America (ASA), 2012)This study reports an investigation of the well-known context-dependent variation in English /r/ using a biomechanical tongue-jaw-hyoid model. The simulation results show that preferred /r/ variants require less volume ... -
The temporal window of audio-tactile integration in speech perception
(Acoustical Society of America (ASA), 2010)Asynchronous cross-modal information is integrated asymmetrically in audio-visual perception. To test whether this asymmetry generalizes across modalities, auditory (aspirated "pa" and unaspirated "ba" stops) and tactile ... -
Locating de-lateralization in the pathway of sound changes affecting coda /l/
(Ubiquity Press, Ltd., 2020)‘Vocalization’ is a label commonly used to describe an ongoing change in progress affecting coda /l/ in multiple accents of English. The label is directly linked to the loss of consonantal constriction observed in this ... -
The impacts of a community-based health education and nutritional support program on birth outcomes among migrant workers in maesot, thailand: A retrospective review
(2020)Since 2014, The Charis Project and later Shade Tree Foundation have been conducting community-based interventions focusing on nutritional support and education for pregnant and nursing mothers to alleviate immediate human ... -
Phonological contrast and phonetic variation: The case of velars in Iwaidja
(Project Muse, 2020)A field-based ultrasound and acoustic study of Iwaidja, an endangered Australian Aboriginal language, investigates the phonetic identity of nonnasal velar consonants in intervocalic position, where past work has proposed ... -
Mask-less oral and nasal audio recording and air flow estimation for speech analysis
(Institution of Engineering and Technology (IET), 2019)Here is demonstrated Rivener, a mask-less oral and nasal audio recorder and air flow estimation system. This system records audio and low-frequency pseudo-sound from the nares and mouth. The system does not interfere with ... -
Native language influence on brass instrument performance: An application of generalized additive mixed models (GAMMs) to midsagittal ultrasound images of the tongue
(2019)This paper presents the findings of an ultrasound study of 10 New Zealand English and 10 Tongan-speaking trombone players, to determine whether there is an influence of native language speech production on trombone ... -
Tri-modal Speech: Audio-visual-tactile Integration in Speech Perception
(2019)Speech perception is a multi-sensory experience. Visual information enhances [Sumby and Pollack (1954). J. Acoust. Soc. Am. 25, 212–215] and interferes [McGurk and MacDonald (1976). Nature 264, 746–748] with speech perception. ... -
Visual-Tactile Speech Perception and the Autism Quotient
(Frontiers Media SA, 2019)Multisensory information is integrated asymmetrically in speech perception: An audio signal can follow video by 240ms, but can precede video by only 60ms, without disrupting the sense of synchronicity (Munhall et al., ... -
Visual-tactile integration in speech perception : evidence for modality neutral speech primitives.
(Acoustical Society of America (ASA), 2016)© 2016 Acoustical Society of America. Audio-visual [McGurk and MacDonald (1976). Nature 264, 746-748] and audio-tactile [Gick and Derrick (2009). Nature 462(7272), 502-504] speech stimuli enhance speech perception over ... -
Aero-tactile integration during speech perception: Effect of response and stimulus characteristics on syllable identification
(Acoustical Society of America (ASA), 2019)Integration of auditory and aero-tactile information during speech perception has been documented during two-way closed-choice syllable classification tasks [Gick and Derrick (2009). Nature 462, 502–504], but not during ... -
Three-dimensional printable ultrasound transducer stabilization system
(2018)When using ultrasound imaging of the tongue for speech recording/research, submental transducer stabilization is required to prevent the ultrasound transducer from translating or rotating in relation to the tongue. An ... -
Using a radial ultrasound probe's virtual origin to compute midsagittal smoothing splines in polar coordinates
(University of Canterbury. New Zealand Institute of Language, Brain & Behaviour, 2015)Tongue surface measurements from midsagittal ultrasound scans are effectively arcs with deviations representing tongue shape, but smoothing-spline analysis of variances (SSANOVAs) assume variance around a horizontal ... -
Super-imposing maxillary and palatal locations for electroarticulometry: A SIMPLE method
(University of Canterbury. New Zealand Institute of Language, Brain & Behaviour, 2015)This study proposes a method of superimposing a physical palatal profile, extracted from a speaker’s maxillary impression, onto real-time mid-sagittal articulatory data. A palatal/dental profile is first obtained by ... -
Three speech sounds, one motor action: Evidence for speech-motor disparity from English flap production
(University of Canterbury. New Zealand Institute of Language, Brain & Behaviour, 2015)The assumption that units of speech production bear a one-to-one relationship to speech motor actions pervades otherwise widely varying theories of speech motor behavior. This speech produc- tion and simulation study ...
