Here we present a general description of this imaging technique and explore its manifold applications to acoustic phonetics. The TCIF spectrogram shows the locations of signal components with unrivalled precision, eliminating the blurring and smearing of components that hamper the readability of the conventional spectrogram. Formants of vowels and other resonants are shown with great accuracy by observing glottal pulsations at very short time scales with a wideband analysis. A further post-processing technique is also described, by which signal components such as formants, as well as impulsive events, can be effectively isolated to the exclusion of other signal information. When the phonation process is examined this closely, a variety of evidence surfaces which supports recent developments in the theory and computational simulation of aeroacoustic phenomena in speech. Narrowband analysis is also demonstrated to permit pitch tracking with relative ease.<\/jats:p>","DOI":"10.1159\/000121375","type":"journal-article","created":{"date-parts":[[2008,4,18]],"date-time":"2008-04-18T12:55:49Z","timestamp":1208523349000},"page":"237-262","source":"Crossref","is-referenced-by-count":5,"title":["Phonetic Applications of the Time-Corrected Instantaneous Frequency Spectrogram"],"prefix":"10.1515","volume":"64","author":[{"given":"Sean A.","family":"Fulop","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2008,4,17]]},"reference":[{"key":"p_1_37","doi-asserted-by":"crossref","first-page":"1068","DOI":"10.1109\/78.382394","volume":"43","author":"Auger F.","year":"1995","journal-title":"IEEE Trans.
