 What is a spectrogram? Frequency over time They provide: 1. Frequency 2. Time/duration 3. Intensity (darker bands) 4. Disturbances (actual bands- we ID "typical" disturbances from "atypical") Spectrogram vs Spectrum Duration/time Spectrums- is a SINGLE point in time and are good for displaying harmonics What is the most commonly used spectrogram? Wideband spectrogram Emphasize the peaking of resonances that occurs within the phonotory pathways; The duration component captures the "timing" of changes within the vocal tract What spectrogram would we use for analysis of intonation patterns? Narrowband What are the "white-ish" striations within the Wideband spectrogram? 1. Pauses 2. Stops 3. Closed phase of VFV What "filter" is generally associated w/ the source filter representation of speech, acoustics quantities? Formant Frequencies Fix: The higher/lower the vowel the higher/lower placement of F1. The higher the vowel the lower placement of F1. (tongue placement) The lower the vowel the higher placement of F1. What does F0 stand for? F0= fundamental frequencies What would the absolute INTENSITY of a sound be if it was doubled? 3 dB What would the absolute PRESSURE of a sound be if it was doubled? 6 dB What is fundamental frequency? f 0- The lowest frequency of vibration in a complex wave Twice the f 0 is called the second harmonic = f 2
