1. A respiratory function testing system, comprising:
an air transforming device, configured to collect a user's respired air for a predetermined period and generate a wide-frequency sound signal according to the collected respired air, wherein the wide-frequency sound signal comprises an ultrasonic signal;
a sound reception device, configured to receive and record the wide-frequency sound signal, and to store the recorded wide-frequency sound signal as an audio file; and
an operation device, configured to communicate with the sound reception device and to receive the audio file;
wherein the operation device is configured to convert the audio file into a spectrogram;
wherein the operation device is configured to use 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.
