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 ... -
Learning effects in multimodal perception with real and simulated faces
(Australian Speech Science and Technology Association Inc., 2019)We have all learned to associate real voices with animated faces since childhood. Researchers use this association, employing virtual faces in audiovisual speech perception tasks. However, we do not know if perceivers ... -
Aero-tactile integration in fricatives: Converting audio to air flow information for speech perception enhancement
(ISCA, 2014)We follow up on research demonstrating that aero-tactile information can enhance or interfere with accurate auditory perception among uninformed and untrained perceivers [1, 2, 3]. We computationally extract aperiodic ... -
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 ... -
Vowel identity conditions the time course of tone recognition
(2013)Using eye-tracking in a visual world paradigm, we sought converging evidence for the time course of Mandarin Chinese tone recognition as predicted by the availability of information in f0 and past results from a ... -
Duration of Blackfoot /s/: A comparison of assibilant, affricate, singleton, geminate and syllabic /s/ in Blackfoot
(2006)A study comparing the duration of assibilant, affricate, singleton, geminate and syllabic /s/ from the citation speech of one speaker demonstrated significant differences in the duration of geminate /s/ (µ = 300 ms), ... -
Aero-tactile integration in Mandarin
(Australian Speech Science and Technology Association Inc., 2019)Previous research has shown that audio-aligned air puffs applied to the skin can enhance the perception of speech audio [12]. In this study, we applied dynamically varying air flow during two-way forced-choice ... -
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 ... -
Hearing, seeing, and feeling speech: A pilot EEG study
(2018)A large number of EEG studies have shown that auditory-visual signals lead to a neurophysiological processing advantage compared to auditory-only signals. Behavioral speech perception studies have shown that tactile stimuli ... -
Audio-Visual-Tactile integration in speech perception.
(2018)Behavioural audio-visual research has shown enhancement1 and interference2 in speech perception, as has behavioural audio-tactile research3. However, to date, we have not encountered any experimental behavioural research ... -
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 ...
