Burst spectra and place of articulation in read speech
Richard S. McGowan · The Journal of the Acoustical Society of America · 1999
The burst spectra of voiceless stop releases are examined with a set of wide-band filters. These spectra are selected from one male speaker and one female speaker of American English, each reading from a list of 100 sentences. A set of rules is proposed for inferring place-of-articulation based on filter amplitudes obtained from a training set of utterances. The formulation of these rules is aided by segregating the data according to speaker and according to the second formant frequency at voice onset of the following vowel. This work is part of a project to infer articulatory movement from speech acoustics. [Work supported by the NIH through Grant No. DC-01247.]
