Identification of resynthesized /hVd/ utterances: Effects of formant contour Export

@article{citeulike:2448920, abstract = {The purpose of this study was to examine the role of formant frequency movements in vowel recognition. Measurements of vowel duration, fundamental frequency, and formant contours were taken from a database of acoustic measurements of 1668 /hVd/ utterances spoken by 45 men, 48 women, and 46 children [Hillenbrand et al., J.

Pattern recognition results showed that a simple approach to vowel specification based on duration, steady-state F0, and formant frequency measurements at 20\% and 80\% of vowel duration accounts for much but by no means all of the variation in listeners' labeling of the three types of stimuli. \©1999 Acoustical Society of America.}, author = {Hillenbrand, James M. and Nearey, Terrance M.}, citeulike-article-id = {2448920}, citeulike-linkout-0 = {http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=JASMAN000105000006003509000001&idtype=cvips&gifs=yes}, citeulike-linkout-1 = {http://link.aip.org/link/?JAS/105/3509}, citeulike-linkout-2 = {http://dx.doi.org/10.1121/1.424676}, doi = {10.1121/1.424676}, journal = {The Journal of the Acoustical Society of America}, keywords = {formant\_contours, fundamental\_frequency, language, speech, speech\_perception, vowel\_duration, vowel\_recognition, vowels}, number = {6}, pages = {3509--3523}, posted-at = {2009-09-04 19:14:51}, priority = {3}, publisher = {ASA}, title = {Identification of resynthesized /hVd/ utterances: Effects of formant contour}, url = {http://dx.doi.org/10.1121/1.424676}, volume = {105}, year = {1999} }
