Document Summary
Narrow-band spectrogram: shows harmonics in vertical lines: gives good resolution for frequency, blurs time. Wide-band spectrogram: shows thick, horizontal formants: formants, clusters of harmonics with high intensities useful for distinguishing vowels, more useful in phonetics in comparison to narrow-band. Distribution of f1: height of vowel: high tongue, low first formant, low tongue, high first formant. Distribution of f2: backness of vowel: high f2: front vowel, such as [ , low f2: back vowel, such as [u] Resonating frequency is higher for smaller cavity: thus, a high vowel is produced in a smaller cavity, resulting in a higher frequency, and a low vowel is produced in a larger cavity, resulting in a lower frequency. Note: relate f1 with height of back of tongue and f2 with height of front of tongue. High front -> low front -> low back -> high back: i e o u. F1 starts low and rises until the vowel [ ] and then f1 falls.
