* Breathing correctly: Actors need to learn how to breathe from their diaphragms, which is a muscle located below the lungs. This will help them to produce a strong, clear sound.
* Articulating clearly: Actors need to make sure that they are enunciating their words clearly, so that the audience can understand what they are saying. This means opening their mouths wide and using their lips and tongue to form the sounds of words correctly.
* Projecting their voices: Actors need to learn how to project their voices so that they can be heard by the entire audience. This means speaking loudly enough and using their resonating cavities (the sinuses, mouth, and chest) to amplify their sound.
* Using vocal variety: Actors need to learn how to use vocal variety to create interest in their performances. This means varying their pitch, volume, and speed of speech.
Vocal projection is a skill that takes time and practice to develop. However, with the right techniques, actors can learn to project their voices and be heard by their audiences.
