Characteristics of Speech Signals

- The Speech Signal:

✔️ Neither invariant nor linear.

- This means that speech is inherently variable, and its properties cannot be simply defined in a linear
manner.



Speech Signal Processing

- Perceptual Normalization:

✔️ The process by which a listener simplifies speech processing to smooth out superfluous variability.

- Listeners tend to adjust their perception to account for variability in speech, helping them understand
it better despite fluctuations.



Types of Perception

- Quantal Perception in Speech:

✔️ Categorical perception.

- Listeners categorize sounds into discrete groups, which helps in distinguishing phonemes effectively.



Duplex Perception

- Duplex Perception:

✔️ Syllable components are presented separately but simultaneously to each ear.

- This phenomenon allows listeners to perceive both the acoustic properties of syllables and the
interaction of the two components.



The McGurk Effect

- McGurk Effect:

✔️ The place and/or manner of articulation is perceived to change.

- This effect illustrates how visual information (like lip movements) can influence auditory perception,
leading to a mismatch between what one hears and sees.
