On a waveform, this would be highlighted by a periodic sound wave. On a spectrogram, there are two specific visual elements to look out for, which resemble a voiced sound. The first is the vertical ...

the sound waves start bouncing around. Those reflections interfere with each other. Which creates a mix of other frequencies, that you can detect with a spectrogram. So even though your voice ...

Spectrograms present an image of frequencies over time and convey a sound’s volume. They are created by feeding an audio signal into a Fourier transform, a mathematical model for translating ...
