There is a concept in the theatre of cheating outward. Of making certain, sometimes subtly, that your mouth and the direction of your voice is pointed towards the audience.
Sound waves must travel in a medium, in this case, air. Since air is a linear medium, sound waves are linear too.
Sound waves take two forms, they can be longitudinal or transverse. Longitudinal waves travel parallel to the source of the wave and transverse waves travel at 90-degree angles from the source of the wave. There is, of course, much more to know here but this is sufficient understanding for directing your voice into space.
