3. Air in the voice
This effect is also used frequently to make actors sound older than their real age. The same way we whisper, we can mix this flow of air with our voice to sound like an older person. The more air you mix with your voice, the older you will sound. We also have to be careful as some actors naturally put air in their voice, especially when they are tired. Our role is then to recognize the problem and ask them to project their voice more to reduce the airflow.

We just introduced another important parameter, the projection.

4. Projection
This is very often confused with volume. In fact projection and volume are two different parameters of the sound of a voice. The projection can be compared to the acceleration of a car and the volume would be its speed. As we can see, the two things are very close but not quite the same. The projection will be the force with which the actor is sending his voice out of his mouth, at a low or high volume. To project more will give a voice a more dynamic and energetic attitude. At the opposite end of the spectrum, we'll ask an actor to project less to give a calmer or quieter attitude. The projection has a big influence on the attitude, as we can see.

5. Nasal quality, nose, mask area
This effect can only be used when the voice is placed in the high throat. The nose and the mask are placed on the same horizontal axis as the high throat. We'll make a distinction between nose and mask, which will help to dissipate a very common misunderstanding. We'll define the mask as the area where the sinuses are. The nose will be the extremity of the area. These two areas create different effects. The mask is known worldwide because of Bugs, but a lot of actors who cannot separate the two areas, place their voice completely in the nose, which makes them sound like they have a cold and stuffed nose. This also makes the voice muffled and missing clarity. From now on, we'll refer to "mask" for most characterization, unless "nose" is specified.

6. Lisp
Sylvester and Daffy made this effect famous. The lisp, like compression, can be thin or thick (subtle or more pronounced). I recommend the actor put the top of their tongue on the left side of their mouth between the lips. Maybe the fact that we are generally right sided makes this side easier for everybody. (The effect created with the tongue at the center of the lips is different.) Then they have to speak and direct their voice along the tongue. The projection and the amount of air will create different lisps. More projection and more air will create a thick lisp and less projection with a little bit of air will create a thin lisp. If we listen carefully, we'll notice that Sylvester's lisp is thicker than Daffy's.
