transmits through your neck tissue and your oral cavity with the most clarity.
The easiest way to find your sweet spot is to place the electrolarynx on your
neck in different positions and actuate the sound. What you are looking for is
the place on your neck, which transmits sound the best. While looking for a
sweet spot, it is crucial that you press it firmly against your neck tissue, so the
sound transmits through your tissue and out your oral cavity. Take your time
finding your sweet spot this is the most crucial part of learning how to use an
electrolarynx. Finding just the right place will set you up for success.

After you have pinpointed the desired spot, you can start making some basic
sounds. Focus on single vowels first. Over-articulate every sound with your
mouth until you feel comfortable with all the vowels. After that, you can start
practicing short words. Slowly work your way up to sentences and
conversation.
