Basics for reading unlabeled spectrograms, by Rob Hagiwara. A word on sources. I like to divide the kinds of sources in speech into three categories: periodic voicing (or vibration of the vocal folds), non-voicing (which most people don't consider, but I like to distinguish it from my third category), and aperiodic noise (which results from turbulent airflow). Welcome to the Spectrogram! You can draw on the screen to make sound!

A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. When applied to an audio signal, spectrograms are sometimes called sonographs, voiceprints, or voicegrams. When the data are represented in a 3D plot they may be called waterfalls. Spectrograms are used extensively in the fields of music, linguistics, sonar, radar, speech processing, seismology, and others.

For deep learning models, we usually use this rather than a simple Spectrogram. Below, you find my example sourcecode and the corresponding plot. import matplotlib.pyplot as plt import numpy as np from numpy import pi as π from scipy.signal import spectrogram import pywt f_s = 200 # Sampling rate = number of measurements per second in [Hz] t = np.arange (-10,10, 1 / f_s) # Time between [-10s,10s].

Identifying sounds in spectrograms. Let's look at how various kinds of sounds appear on a spectrogram. Vowels. Vowels usually have very clearly defined formant bars, as in the following: In dipthongs, you can see the formants change frequency as the tongue body moves through the mouth: A spectrogram shows how the frequency content of a signal changes over time. It's a 2-dimensional function of amplitude (brightness or color) vs frequency (vertical axis) vs time (horizontal axis): Sometimes this is called a sonogram. The time and frequency axes are sometimes swapped.

If you are anything like me, trying to understanding the mel spectrogram has not been an easy task. You read an article only to be lead to another… and another… and another… on and on it goes. As nouns the difference between spectrogram and scalogram is that spectrogram is a visual representation of the spectrum of a sound changing through time while scalogram is (signal processing) a visual representation of a wavelet transform, having axes for time, scale, and coefficient value, analogous to a spectrogram.

But this is the chief difference. Identifying sounds in spectrograms. Let's look at how various kinds of sounds appear on a spectrogram.
