Source filter model (4) - ANSWER-~ the larynx serves as the sound source and its output is then sent
into the vocal tract which filters it.

~ larynx on its on cant produce any sound unless there is pressure driving it

~ pressure comes from the lungs

~ vocal tract doesn't just filter but resonates or enhances some sounds



Pitch (2) - ANSWER-Stretch the vocal folds to increase their tension and therefore increase the
frequency at which they will vibrate

~ Contracting the cricothyroid muscle



Whisper (2) - ANSWER-~ push air to cause turbulence

~ lungs provide pressure and the vocal folds create constriction to cause turbulence



Phonation - ANSWER-vibration of vocal fold caused from pressure from lungs



Fundamental Frequency - ANSWER-~ the rate at which your vocal folds oscillate

Men: 100-120 times per second

Women: Double that



Harmonics - ANSWER-~ What comes out: the Fundamentals plus the Harmonic components.

~ Exact multiples of the FF

~ If the FF is higher then the space between the harmonics is bigger

, Harmonic Spectral Slope - ANSWER-The Fundamental is the strongest element and the increasing
harmonics get weaker.



Vocal Tract Transfer Function (4) - ANSWER-~the difference between the sound that enters the vocal
tract and the sound that exits.

~ Input to the vocal tract comes from the larynx

~ Output of the vocal tract is what we can hear and record at the lips

~ Output minus the Input



Formants (4) - ANSWER-~ a resonant peak in the vocal tract transfer function

~ some frequencies in a given range are amplified in their amplitude such that they are more
prominent than other sounds in the spectrum.

~ there are many for any given vowel but the first 2-3 are looked at the most

~ it is not a sound source, instead it is showing how the vocal tract is shaping that sound that the
larynx gave to it



Hypokinetic Dysarthria (3) - ANSWER-~ Related to Parkinson's Disease

~ Weak, monotone voice

~ Treated through 1 Stop Shopping



Spasmodic Dysphonia (3) - ANSWER-~ neurolaryngological disorder

~ Strained or strangled voice

~ Treated medically by laryngeal injection



Muscle Tension Dysphonia (3) - ANSWER-~ tight pressured voice

~ Creates excessive muscle activity

~ Treated by laryngeal massage



Analog - ANSWER-~ Means Analogy: one phenomenon is representative of another



Microphone (4) - ANSWER-~ the microphone signal that travels through a wire is analogous to the
pressure that reaches the microphone.
