1. Formula
The fundamental frequency (F0) was calculated using the following formula:
F0 = \frac{1}{T}
where (T) is the duration of one period in seconds.
2. Measured values
| Word | Period (T) (s) | F0 (= 1/T) (Hz) |
|---|---|---|
| 해라 | 0.003038 | 329.16 |
| 흐라 | 0.003197 | 312.79 |
| 호라 | 0.003287 | 304.23 |
| 후라 | 0.003141 | 318.37 |
| 헤라 | 0.003102 | 322.37 |
| 히라 | 0.003049 | 327.98 |
| 허라 | 0.003210 | 311.53 |
| 하라 | 0.003167 | 315.76 |
3. Average F0
The average F0 across the eight vowels is:
\frac{329.16 + 312.79 + 304.23 + 318.37 + 322.37 + 327.98 + 311.53 + 315.76}{8}
= 317.77 \text{ Hz}
So, the average F0 = 317.77 Hz.
