EGG study of Czech phoneme /r/
Keywords:Potential sources, Wave forms
AbstractThe article utilizes electroglottography (EGG) to test for a difference in laryngeal setting as the potential source of acoustic distinction inexplicable by tongue height. Due to the spectrographic evidence which shows that becomes more fricated towards the end of the sound, particularly in word-initial and word-final positions. EGG waveforms were inverted and smoothed using EGG Works. This suggests that the first portion of this sound is simply the glottis transitioning from modal voice to a more open glottis, setting up the conditions necessarily for trilling and breathiness to co-occur, the fact that the trilling happens during the second portion, as well as the high H1-H2 of the portion before frication, supports this claim. This is most evident in the word-initial and word-final positions but also obtains intervocalically for many speakers.
