LING 330 Lecture Notes - Lecture 12: Cakewalk, Vocal Folds, Mobile Equipment Identifier
Document Summary
The result is a very short, voiced stop. It is kind of like getting lazy and letting the vocal folds vibrate the whole way through both vowels and the alveolar stop. /nt/ sequences will optionally become voiced, nasal taps before unstressed syllables. Aspiration is the puff of air forcefully expelled upon release of a stop. Major acoustic cue for presence of a voiceless stop (in english) Easy to spot in waveform as sudden increase in amplitude. Easy to spot in spectrogram as aperiodic, high frequency energy. Also serves to delay voicing of following vowel/sonorant. And so, the listener has more information about what the sound was before the vowel. Aspirated when initial in a stressed syllable ti] Unaspirated after / s / in syllable onsets. Vowel length before the stop has a huge effect in english for stops (has an effect on whether you see the stop as voiced or voiceless) Vowels are shorter when followed by voiceless coda consonants.
