Document Summary

A graph that shows the changes in amplitude of speech sounds over time. Periodic and aperiodic elements are visible indicating the manner of articulation and voicing of a sound. Look a lot like vowels but with less amplitude and less complexity. Periodic but with a very low amplitude. Often followed by a burst when the. What is the glottal source? consonant is released. Aspirated consonants followed by an aspirated sound. The voicing gives it its periodic quality. Represents the different frequencies in a sounds and their amplitude. This is useful for determining sound quality. When certain frequencies are amplified it is indicative of certain sounds (vowels). The vibration of the vocal folds which create a whole array of frequencies. The size and shape of the vocal tract filter out certain vibrations causing certain frequencies to become more amplified and others to be damped out. The frequencies that are amplified are resonant with that particular vocal tract shape.
