The horizontal axis represents time in seconds and the vertical axis represents fundamental frequency in Hz (Hertz). 1 Hz = 1 cycle of vibration per second. The higher the fundamental frequency, the higher the pitch you hear. The example is the phrase white boat, which is an utterance taken from Exercise 5 in Tutorial 3. Click on the loudspeaker icon to hear it.
