Claim 9:
10. A respiratory function testing method, comprising:
collecting a respired air for a predetermined period and generating a wide-frequency sound signal according to the collected respired air, wherein the wide-frequency sound signal comprises an ultrasonic signal;
receiving and recording the wide-frequency sound signal, and storing the recorded wide-frequency sound signal as an audio file;
converting the audio file into a spectrogram; and
using a built-in AI module to decide automatically Signal Onset X1 of the spectrogram, Signal Offset X2 of the spectrogram, Signal Duration W of the spectrogram, and frequency range Y1/Y2 of the spectrogram, wherein the built-in AI module is trained by repeatedly collecting different respired air during different predetermined periods and comparing different spectrograms with respiration results.
