Document Summary
After stop release positive vot value (voiceless stop) Timing of the release of the stop relative to the initiation of the v. f. vibration. Voiced stops vot range = -20ms to +20ms. Narrow constriction results in turbulence: particle motion in air stream becomes very complex. Classified as strident (sibilant) have more intense energy z, s, sh, (mea[s]ure) S, z groove along midline of tongue. Create seal with lateral edges of tongue on medial edges of upper teeth. Sh, soft g" groove is wider; lower frequency band due to larger resonating cavity. /h/ - vocal tract takes shape of following vowel; h is a lot of noise, sometimes slight formant pattern bc youre moving into the vowel. F, v, , energy very low. Non resonant putting stop next to fricative (stop features plus fricative features) (don"t get clear line with affricate) --acoustic features: silent gap, noise burst, extended period of noise. Non-strident/sibilant less intense energy v, f, h, th, th.
