How does voice affect a sound wave or its corresponding waveform?
I would view it as the following:
The letter A is the input to a system, one is your vocal chords the other one mine. Since the system response of your and my vocal chords are different, we would get different outputs.
Now, what would characterize the system response, it would be factors like, rise time/bandwidth, decay response etc. All of this would impact the tone and pitch terminologies usually used in audio/speech. These variables will vary for each user. With different input the response will then also be different . So &quot;b&quot; will not be same as &quot;a&quot;
