Eccentric Interchangeability of the Semi‑Adjustable Articulator: A Pilot Study
… in teaching institutions is the semi-adjustable articulator. Several of these instruments claim interchangeability without loss of clinical accuracy and studies have supported this claim. No studies to date have assessed the interchangeability of the articulators in any relation other than hinge …

Supralaryngeal Articulator Movements and Laryngeal Control in Mandarin Chinese Tonal Production
… of F0 control on vowel quality. Similarly, articulatory compensation was not noted for all participants for tongue height adjustments when the jaw was lowered during different lexical tone productions. To serve as a reference database for theoretical and clinical applications, a larger set …

Determining articulator configuration in voiced stop consonants by matching time-domain patterns in pitch periods
… observed speech signal to the configuration of articulators. Due to the potentially rapid motion of the articulators, the speech signal can be highly non-stationary. The typical linear analysis techniques that assume quasi-stationarity may not have sufficient time-frequency resolution to …

Acoustical study of the development of stop consonants in children
… period. Speech is generated using a series of articulatory, laryngeal, and respiratory gestures that children must learn to reproduce. As a child's speech develops, the gestures become more precise and coordinated, and the resulting acoustic patterns are refined. To explore their development, …

Optimization of acoustic feature extraction from dysarthric speech
… around landmarks provide the identity to articulator-free (manner) and articulator-bound (place) features.

Verification of the Accuracy of Electronic Mandibular Movement Recording Devices: : An in vitro investigation
… patient information to a highly adjustable articulator include mechanical recorders, mechano-electronic recorders and optoelectronic recorders. The purpose of this study is to verify the accuracy of electronic mandibular movement recording devices in vitro. For this investigation an …

Evaluation of two reference planes to the horizon in the natural head position
Dental casts are mounted to dental articulators using anatomical records in order to simulate and duplicate static and dynamic interocclusal relationships. The three dimensional relationship of the maxillary arch to the transverse horizontal axis of the mandible is defined by establishing a third …

The design and use of dental articulators in the United States from 1840 to 1970
… are many bits of information concerning dental articulator use and design which have been put into this single source. It developes a new classification of dental articulators into eighteen types. This classification is based upon a sorting of mandibular movements recognized by the dental …

The voice-bar after closure of coda consonants in the speech of young children
… insight into the speech acquisition process and articulator development of young children whose mother-tongue is American English. The presence of voice-bars after the closure of voiceless coda consonants in consonant-final words from early child speech is not consistent with the idea that …

Nasal codas in Standard Chinese : a study in the framework of the distinctive feature theory
… a framework for quantifying the acoustic and articulatory patterns observed in the two languages. An acoustic model of nasalization is first presented, in which the area of the velopharyngeal port and the place of oral constriction are varied, in order to observe the behavior of the acoustic …

Multimodal speech recognition with ultrasonic sensors
Ultrasonic sensing of articulator movement is an area of multimodal speech recognition that has not been researched extensively. The widely-researched audio-visual speech recognition (AVSR), which relies upon video data, is awkwardly high-maintenance in its setup and data collection process, as …

DA LAPA AO PELOURINHO: ONDE VIVE A MALANDRAGEM? O SURGIMENTO DO PERSONAGEM MALANDRO E SUA COMPARAÇÃO NAS OBRAS DONA FLOR E SEUS DOIS MARIDOS, DE JORGE AMADO, E A ÓPERA DO MALANDRO, DE CHICO BUARQUE
… the malandro as a provocateur of conflicts and articulator, oblivious to a Manichean balance. Observing political variations, the malandro transforms and adapts to maintain his existence. Faced with the examples of different authors, we perceive the decline of the character until his definitive …

Analysis of the pressure-wall interaction at the release of a stop closure
In producing a stop consonant, a soft tissue articulator, such as the lower lip, the tongue tip, or the tongue body, is raised to make an airtight closure. Stevens [I] pp 32 9-3 30 hypothesized that the interaction of the air pressure with the yielding soft-tissue wall would lead to a …

Setting an articulator using NewTom 3G measurements is not a time-saving technique when compared to the Cadiax.</p> <p>The following conclusions were made:</p> <p>1) A new method for obtaining sagittal eminential angle (SEA) and progressive mandibular lateral …

Effect of Centric Interference on Canine Tooth Wear
… T4 models were articulated using a Panadent® Articulator and evaluated for dental interferences and CO/MIP variance using the incisal pin locator. The canines were evaluated for volumetric CTW from T2 to T4 using Geomagic Control (3D Systems, South Carolina 2014). Intraclass correlation test …

Using articulatory adjustment to compensate for hypernasality - a modeling study based on measures of electromagnetic articulography (EMA)
… an approach that uses speech-dependent articulatory adjustments to reduce hypernasality caused by excessive velopharyngeal opening. A preliminary study has been done to derive such articulatory adjustments for hypernasal /i/ vowels based on the simulation of an articulatorymodel (Speech …

Towards a phonetic and phonological typology of post-velar articulation
… about post-velars based on Semitic data and articulatory modelling. Interior Salish phonological data support the extension of articulator-based feature geometry to a fourth node, here termed Tongue Root. It is shown that the fourth node is required to class Interior Salish faucals and …

Henry James and the moral will
… Fleda for the most part stands as a forceful articulator of moral values, although she sometimes restricts her awareness of the consequences of her actions. <em>What Maisie Knew</em> demanded my consideration, since it depicts the education of its heroine as largely involving how to assert …
