Speech And Hearing Science

Front 1

A Formant is ( F0):

Back 1

The resonating frequency of the vocal tract.

Front 2

Formant 1 (F1) is:

Back 2

The frequency that is related to the volume of the pharyngeal cavity as well as to how tightly the vocal tract is constricted. It is considered the lowest frequency and the most intense.

Front 3

Formant 2 ( F2) :

Back 3

The frequency related to the length of the oral cavity.

Front 4

Rarefraction:

Back 4

is considered an area of lower pressure between two molecules. The lesser the pressure the more negative the pressure.

Front 5

Compression:

Back 5

An area of high pressure when molecules collide and are tightly packed together. This is considered an area of positive pressure.

Front 6

Harmonics to Noise Ration:

Back 6

Is a measure of the proportion of harmonic sound to noise in the voice measured in decibels.

Front 7

Complex sound:

Back 7

is defined as a wave consisting of two or more frequencies. Two types period and a periodic. (Ex)
Periodic: vowels
Aperiodic: voiceless Stops /p,t,k/, voiceless fricatives /f,s,and h/.

Front 8

Electroglottagraphy:

Back 8

A method of evaluating vocal fold function based on the difference between electrical conductivity of tissue and air; also called laryngography.

Front 9

Spectrogram

Back 9

a visulization of sound or sounds over time in terms of the amount of acoustic energy at different frequencies. In other words it is a method that identifies frequency, amplitude, and duration of sounds.
Frequency is displayed on vertical axis, Time is represented on the horizontal axis and intensity of acoustic energy is represented by darkness of the the trace on the screen.

Front 10

What are the attributes of sound?

Back 10

Frequency, Pitch, Amplitude, Intensity, and Loudness.
