Study Notes
Speech Perception: Cues for Stops
- Stop consonants are articulated with a complete closure in the vocal tract, followed by a release burst.
- They differ acoustically, making description complex.
- Key features include Manner, Place, and Voicing.
Introduction to Stop Consonants
- Stops (or Plosives) involve a momentary closure in the vocal tract, with a subsequent release of air.
- Common examples include /p/, /b/, /t/, /d/, /k/, and /g/ in English.
- Closure duration varies across languages and types of stops (voiceless vs. voiced).
- Duration typically ranges from 50-100 ms.
- Burst duration is generally 5-40 ms.
Manner of Articulatory Cues
- Closure Duration/Silent gap is the interval during complete obstruction of the vocal tract.
- Release burst is the noise produced at the release.
- Formant transitions are changes in formant frequencies reflecting vocal tract movements during and after the stop.
- Voice Onset Time (VOT) is the time between the release burst and the onset of voicing.
Place of Articulatory Cues
- Spectral shape of the burst varies according to the point of closure.
- Frequency position of the burst relative to vowel frequencies provides information.
- Burst amplitude differs based on the constriction location.
- Closure duration is the duration of the complete closure.
- Rate of formant transitions is rapid for bilabial sounds relative to those of velars.
- Transition duration varies based on place and manner of articulation.
- Formant transitions are changes in frequency bands during the movement of the articulators.
Voicing Cues
- Voice onset time (VOT) is critical for distinguishing voiced from unvoiced stops.
- Formant transitions are cues for voice onset.
- F1 transition onset and offset, and F1 cutback before and after closure are features that help distinguish voicing
- Voice bar is a spectral cue that appears on a spectrogram as evidence of voicing.
