Measuring magnitude of tongue movement for vowel height and backness
نویسندگان
چکیده
Optical Flow Analysis (OFA) has recently been introduced as a fast, easy, and reliable means of extracting articulatory information from ultrasound video ([2], [3], [6], [9]). This paper illustrates how one primary measurement that is extracted using OFA, magnitude of movement, correlates with the standard phonological vowel categories of height and backness. By establishing a baseline for these measures, we pave the way for future studies to examine how magnitudes change in particular phonological, social, or other contexts.

An Acoustic and Articulatory Analysis of Vowels in Ningbo Chinese
This paper examines the acoustic and articulatory aspects of vowel production in Ningbo Chinese. Frequency results show that ten normal-length vowels can be well distinguished by four levels of vowel height and two levels of vowel backness in an acoustic F1/F2 plane. Acquired EMA data show that there is no clear correlation between vowel height and articulatory parameters. Results from a PARAFA...

A common assumption about vowel formants is that F1 inversely correlates with tongue height and F2 inversely correlates with tongue backness. This study compared vowel formants and corresponding lingual articulation in Australian English (AusE) for nearly all of the AusE monophthongs. Simultaneous acoustic and electromagnetic articulography (EMA) recordings are reported for four speakers produc...
متن کاملA comparison of acoustic and articulatory methods for analyzing vowel differences across dialects: Data from American and Australian English.
In studies of dialect variation, the articulatory nature of vowels is sometimes inferred from formant values using the following heuristic: F1 is inversely correlated with tongue height and F2 is inversely correlated with tongue backness. This study compared vowel formants and corresponding lingual articulation in two dialects of English, standard North American English, and Australian English....

We use real-time magnetic resonance imaging (rtMRI) as a tool to investigate post-glossectomy speech by examining articulatory behavior. Our data reveal that listeners perceive speech produced by postoperative partial-glossectomy patients whose surgical procedure most affected the base of tongue to be typical, while speech produced by patients whose procedure affected the oral tongue is perceiv...

The study presents a kinematic and acoustic comparison of the vowel spaces of New Zealand English (NZE) and Australian English (AE). Five talkers of NZE (3F and 2M) and 5 female talkers of AE each produced between 9 15 tokens of monophthongs in HEAD, HID, HAD, HERD. For each token, measurements of lip aperture, lip protrusion, jaw height, and tongue height and backness were made, in addition to...
