Class 2 Sounds - Voiced Continuants
Introduction
Voiced Continuants are sounds that are produced by combining voicing with constrictions in air flow through the vocal tract, with different sounds being produced by varying the place and the amount of constriction. These include L, M, N, R, V, W, and TH+ (with voice).
An example of this would be the difference in the placement of the tongue and lips when saying "LA" versus "MA". Both sounds involve voicing and a constriction of the air flow by the lips and tongue, but the placement of the latter two varies depending on the sound being produced.
Physiology
Physical characteristics of producing Voiced Continuant sounds include:
- Closure of the vocal folds
- Contraction of muscles needed to initiate movement of the air stream
- Activation of the voice
- Movement of the tongue and lips to a specific location
- Varying the degree on constriction for both the tongue and lips
