Do you speak from your throat?

Or, do you or know someone that does? It can sound grating, and generally lacks tone and dynamics.  One thing I see and hear often with students or just speakers in general, is that they speak from the Larynx, which can be tiring and sound strained.  What you might not realise is that there are a lot more areas of resonance that you can tap into (literally), which will give you more projection and colour to your voice.
