LIN228H1 Lecture Notes - Lecture 5: Vocal Tract, Blue Box, Spectrogram
Document Summary
Lin228 l ec tu r e 5. /i/ tongue high up, lips slightly open, /u/ tongue high back, lips rounded. Think of your vocal tract as a tube that can change shape. When producing the vowels, we create two major cavities within the vocal tract: o o. Front cavity anything in front of the highest position of the tongue. Back cavity anything behind the highest position of the tongue. We can describe vowels on the size of their cavities o. Important consequences on acoustics since a cavity will carry with it its own resonance; if cavity is large we get a lower resonating frequency vs. small cavity, we get a higher resonating frequency. /u/ front and back cavities large; front cavity is large since we round our lips, which provides some extra space. Consequences of cavity size: larger cavity = lower frequency, smaller cavity = higher frequency o o.
