COMD 5070 - Module 9 - ConsonantsPlace, Manner, Voicing Chart 
 
 
Hello Heterogeneity 
• vowels have a lot in common 
-all voiced, openness of vocal tract, formants 
• consonants differ greatly 
-degree of constriction, presence or absence of noise, nasality 
• more to go wrong with consonants = gainful employ for SLPs 
 
 
 
Categories of Consonants

COMD Module 5Phonation 
the production of sound as the vocal fold vibrates; Reptiles, amphibians, and mammals all have a larynx to produce voice. Animal sounds are excellent examples of voice as a distinct element of speech as they do not have sophisticated articulation or resonance as humans do. 
 
 
There are 3 primary components to voice: 
The generator: the breath stream from the lungs 
 
The vibrator: the vibration of the vocal folds as the breath stream passes through closed vocal folds 
 ...
