A question I often ask students is what brings our voice into play. I point out that as they sit quietly listening to me, there is no voice and no sound. The answers I get are always well-informed and breath, vocal cords, the diaphragm and vibrations are usually mentioned. But it sometimes takes a bit of prodding until someone eventually comes up with the brain or thought.
Our voice happens through our need to communicate something. We have a thought we wish to share, and the desire to share it sets off a little chain of physical ‘events’ in our body, beginning with us taking in a breath.
The breath causes a vibration, vibration creates sound and sound is shaped into speech. This begins with a coordinated movement between our breath and certain muscles in our abdomen which generates the energy we need to power our voice and sustain it once we start speaking. And all this happens in a split second as an immediate response to our thought.
