The Acquisition of English stops by Saudi L2 Learners
Researchers have studied voice onset time (VOT) in a number of languages but there is a scarcity of research on the acquisition of VOT of English, particularly by adult Saudi learners, and on the VOT of Saudi Arabic. The current study aims to fill these gaps. At the same time, we aimed to assess …

Harðhljóð og linhljóð: Um aðröddunartíma í íslensku, sænsku og búlgörsku
Voice Onset Time (VOT) is the time between the release of a stop consonent and the onset of voicing (vibrations in the vocal cords). This time is measured in ms and is negative for voiced stops and positive for unvoiced stops. VOT of +75ms and more is considered to indicated an aspirated stop. This …

Frequency, Attention, and Phonetic Characteristics that Influence the Right-Ear Advantage for Speech Perception
… properties of stimuli, viz., voice onset time (VOT) and place of articulation (POA). Participants heard monosyllabic rhyming words from the Halwes (1990) Fused Dichotic Word Test and were instructed to attend to the left or right ear, or to divide attention equally. Stimuli in Experiment 1 were …

Second Dialect Acquisition of North Korean Refugees in Seoul
… directly compared to each other by measuring VOT, F0, and H1-H2. In addition to providing acoustic analyses of stop production in NK and SK, effects of various sociolinguistic factors on stop production have been statistically investigated. Moreover, topic-based style shift and interlocutor …

Effectiveness of visceral osteopathic treatment on gastrointestinal indicators and behaviour patterns in autistic children: using questionnaire and biochemical markers to measure outcomes
… and after visceral osteopathic techniques (VOT), and to link these findings with contemporaneous questionnaires. These data assessed whether GI status could be reliably determined from a single sample, whether VOT affected behaviour and clinical signs, and whether there was any association …

A cross-linguistic study of certain temporal features of speech in stuttering and nonstuttering children
… Experiment one investigated voice onset time (VOT) of word-initial voiced and voiceless bilabial and apical stop plosives in isolated eve nonsense syllables. The VOTs were measured from oscilloscopic displays. Nonparametric statistical treatment identified certain trends in the data. …

Interactive Development Of F0 As An Acoustic Cue For Korean Stop Contrast
… phonetically differentiated by Voice Onset Time (VOT), but with a tonogenetic sound change in progress, the role of fundamental frequency (F0) has been amplified for distinguishing between Korean stop contrasts with the loss of VOT differentiation in young adults’ production. The present study …

Aircraft state estimation using cameras and passive radar
… and a comprehensive visual object tracking (VOT) system. Both applications require a solution to the MTT problem, for which the MTTF was utilized. The VOT system performed well on real data recorded at the University of Cape Town (UCT) as part of this investigation. The system was able to …

Structure incorporation of model uncertainty for Bayesian adaptive tracking and its application to maritime surveillance
Adaptive visual object tracking (VOT) is one of the fundamental tasks in machine vision, with active research and far-reaching implications. Bayesian methods are commonly used in adaptive VOT. However, we propose that the current tendency is to restrict the inference to a subtask (e.g. …

Perception and analysis of Spanish accents in English speech
… vowel length, stress, voice onset time (VOT), or segmental accuracy. Nineteen native English speaking listeners rated speech samples from 7 native English speakers and 15 native Spanish speakers for comprehensibility and degree of foreign accent. The speech samples were analyzed …

Neurophysiologic and Behavioral Measures of Phonetic Perception in Adult Second Language Speakers of Spanish
… (CV) stimuli that differed in voice onset time (VOT) from -50 to 30 ms VOT (/ba/ to /pa/). The -50 ms VOT stimulus was paired with each of the others to form stimulus pairs with varying degrees of acoustic difference. Behavioral data showed that L2 listeners of Spanish perceived a transition from …

Quantifying Road User Costs with Heterogeneous Value of Motorists' Travel Time
… costs, accident costs, and value of time (VOT). The term ?value of time? refers to monetary equivalent of travel time wasted due to rehabilitation projects. In current practice, STAs assume VOT as homogeneous within their respective states. This leads to inaccurate RUCs calculations and …

Modifying TRANSIMS (Transportation Analysis and Simulation) to Include Dynamic Value Pricing and Departure Time Choice
… particularly the heterogeneous value of time (VOT). TRANSIMS (Transportation Analysis Simulation System) differs from current travel demand forecasting methods in its underlying concepts and structure. These differences include a consistent and continuous representation of time, a detailed …

A Comparative Variationist Analysis of Phonetic Variation and Change in Toronto Heritage Tagalog
… are examined: the F2 of /u/, voice onset time (VOT) of /p t k/, and the realization of /r/. Inter-group comparisons and multivariate analyses reveal distinctive patterns. Focusing on Heritage Tagalog, results demonstrate that the F2 of /u/ exhibits stable variation whereas the VOT of /p t k/ and …

Voice onset time variation in stop consonant to vowel transitions
… duration is dependent on voice onset time (VOT) variation among the participants. This study could serve as a basis to encourage further research analyzing neuromotor and physiological articulatory control, which could lead to interventional treatment for individuals having dysarthria.

Work Zone Analysis Under Detour Settings
… to a monetary value using value of time (VOT). The work zone set-up cost and accident cost relate to number of work zone segments and total length of work zone. This thesis illustrates the importance of considering the opportunity for detours when considering the design of work zones for …

The Effect and Potential of Digital Health in The Cycle of Care in Tuberculosis Patients from Low and Middle-income Countries
… and one involved video observed therapy (VOT). Grouped analysis of all included studies yielded a marginal improvement in positive patient treatment outcomes (RR 1.05, 95% CI 1.02 - 1.09). Conclusion DH interventions show promise in improving patient adherence and positive treatment …

Prosodically Induced Acoustic Variation in English, Korean, and Hindi
… with and without contrastive focal accent. VOT and FO at the onset of the following vowel are measured as the main acoustic correlates of the laryngeal features in stops, in conjunction with vowel duration and the first and second formant frequencies for vowels. Measurements are taken from …
