Properties of Waves
Speech Wave Representations
Perception
100
Sound waves are these kind of wave, in which the vibration of the medium is parallel to the direction that the wave travels.
What are longitudinal waves?
100
This is an annotated example of this type of speech wave representation.
What is a spectrogram?
100
The process of hearing and understanding speech.
What is speech perception?
200
This property of a wave is defined as the duration of time for one wave – in other words, the time for a particle on a medium to make one complete vibrational cycle .
What is period?
200
This is an annotated example of this kind of speech wave representation.
What is a waveform?
200
We automatically classify the speech sounds we hear into distinct categories of speech sounds, specifically individual phonemes.
What is categorical perception?
300
This property of a wave corresponds qualitatively to pitch, being defined as how many waves occur within a given period of time.
What is frequency?
300
Unlike spectrograms, waveforms do not show this property of waves at all.
What is frequency?
400
This property of a wave corresponds qualitatively to loudness, being the height of the wave (in other words, the maximum amount of displacement of a particle on the medium from its rest position).
What is amplitude?
400
This natural class of speech sounds tends to appear display with aperiodic high frequency bands on spectrograms.
What are fricatives?
500
Sound waves are complex waves. Complex waves are made up of these added together.
What are simple waves?
500
These speech sounds tend to appear with a brief band of near or total silence on spectrograms, corresponding to a period of complete air tract occlusion during articulation.
What are stops?
