Document Summary

Problem is that speech is a three-dimensional thing. Take the frequency and put it on the y-axis, time on the x-axis, and amplitude/intensity is. It has frequency, intensity and fades over time shown in the graph by darkness. When you are speaking, you tend to get four (cid:498)fore-mans(cid:499) in the graph of the spectrum. The machine that produces the graph is called a spectrograph it produces the spectrogram. Every item has its own certain resonance. Then, you need a resonator for all resonances of speech so that it can pick language up. Then, you need a machine that reverses the input of the resonator in order to play back the speech. If the resonator picks up speech, and you reverse it with a vocotor, it will produce the speech and language of what was originally inputted. The top two foramens do not produce much or are not used for much.
