The muscles in the back of your tongue help you make certain sounds, like the letters k and hard g (like in the word go). Try saying these letters slowly, and you'll feel how the back of your tongue moves against the top of your mouth to create the sounds. The back of your tongue is important for eating as well. Once the food is all ground up and mixed with saliva (say: suh-LYE-vuh), or spit, the back muscles start to work.
The tongue is the most important articulator of speech. This muscle is extremely strong, as it must move food around in our mouths as we chew. Its other biological function is to push the food into a bolus (I prefer the less scientific term glob), and then push it down the oesophagus to our stomach. Try swallowing to feel the strength of your tongue pushing down and back. Speech, on the other hand, requires a very different approach. For the sound to resonate effectively, the less tongue root tension (i.e. tension in the extrinsic muscles of the tongue), the better. For speech you want to relax the tongue up and forward, the opposite of swallowing.
