    Abstract: A kinematic experiment investigated tongue movement for vowels in American English with the aim of developing spatial targets for use by subjects in real-time interactive learning/remediation environments. A 3D EMA system (AG501, Carstens Medezinelektronic, GmbH) was used to track the position of the tongue (tongue tip, TT, and tongue back, TB) and lips (upper lip, UL, and lower lip, LL) of adult subjects producing the vowels of American English (12 monophthongs and 3 diphthongs) in the consonant environment /bVb/. Here, we asked which of the tongue sensors yields the best spatial separation of the corner vowels /i/, /u/, /æ/ and /ɑ/, and whether vowels that are acoustically close in formant space (e.g., the pairs /i/-/I/ and /e/-/ɛ/) are distinguishable by tongue sensor position. Data were recorded for ten talkers. Points taken at the vowel midpoint of each production were plotted to determine the spatial separation (Euclidean distance) between each vowel region (centroid). Preliminary results suggest TB sensors yield the most discriminable patterns for corner vowels. Tense/lax pairs show smaller differences, as predicted by acoustic theory. For most vowel contrasts examined, patterns of spatial separation appeared sufficient for real-time feedback applications.

    Using electromagnetic articulography with a tongue lateral sensor to discriminate manner of articulation
    Acoustical Society of America (ASA) ; 2017

    Abstract: This study examined the contributions of the tongue tip (TT), tongue body (TB), and tongue lateral (TL) sensors in the electromagnetic articulography (EMA) measurement of American English alveolar consonants. Thirteen adults produced /ɹ/, /l/, /z/, and /d/ in /ɑCɑ/ syllables while being recorded with an EMA system. According to statistical analysis of sensor movement and the results of a machine classification experiment, the TT sensor contributed most to consonant differences, followed by TB. The TL sensor played a complementary role, particularly for distinguishing /z/.

    Using lateral sensors in flesh-point tracking of /I/ and /ɹ/ in American English
    Acoustical Society of America (ASA) ; 2014
    In:  The Journal of the Acoustical Society of America Vol. 135, No. 4_Supplement ( 2014-04-01), p. 2198-2198

    Abstract: Whereas electromagnetic articulography (EMA) studies commonly use a midsagittal sensor array to record articulatory patterns, higher spatial imaging data (e.g., MRI, ultrasound) suggest that some sounds, such as /ɹ/ and /I/, involve tongue concave/convex shape differences that are more effectively measured along a coronal axis. We therefore explored the use of a lateral sensor in the EMA measurement of liquid consonants. Ten adult subjects produced /I/ and /ɹ/ in /ɑCɑ/, /iCi/, and /uCu/ syllables while seated in a 3D electromagnetic articulography system (AG501, Carstens Medezinelektronic, GmbH). Speech movement was tracked for tongue sensors (tongue tip, TT, tongue lateral, TL, and tongue body, TB) and lips (upper lip, UL, and lower lip, LL). Preliminary results suggest that the TL sensor, taken together with TT and TB, provide an improved characterization of American English liquid consonants. Further results will be discussed in the context of developing methods to optimize real-time speech training and speech rehabilitation systems.
