<br/>   abstract  = {The paper is focused on supporting evidence for the hypothesis [1] that in 
speech perception Ɵ/γ-oscillations segment the auditory stream into syllables and their
subunits. Each Ɵ-cycle is synchronous to a syllable and the γ-cycles, embedded in a 
Ɵ-cycle, correspond to phases, which segment a syllable into subunits realized by articulatory gestures. I claim that these phases are instances corresponding to the start of 
motor programs steering the articulators for producing the gestures and that these 
phases can be reconstructed from the auditory stream by temporal auditory cues. To 
make evidence for this hypothesis, two temporal auditory cues defined by the temporal 
position of the maximal increase and defined by the temporal position of the maximum 
of the loudness course in the nucleus of the syllable (vowel region) are investigated. 
These two cues are input to two linear classifiers for estimating the temporal instance 
of two phases φ0 and φ1 of a syllable. φ0 denotes the start of the motor programs 
steering the articulatory gestures corresponding to the onset consonants of a syllable.
φ1 denotes the start of the nucleus-gesture for achieving the target of the articulators
in the production of the nucleus. For evaluating the quality of the classifiers, φ0 and 
φ1 are extracted from an articulatory database. In the experiments performed, for the 
phase φ0 a precision of 113ms and for the phase φ1 a precision of 23ms is achieved. },
