When you press the electrolarynx to your neck or place the oral tube in your mouth, and press a button, the device sends sounds and vibrations to your throat.

You then form words with your lips and tongue to speak. In general, you should avoid screaming or raising your voice.

Speak slowly and in brief sentences. An electrolarynx is a battery operated machine that produces sound for you to create a voice.

After surgery to remove the whole of your voice box (total laryngectomy), you are no longer able to speak in the normal way. But there are different ways you can communicate and learn to speak again.
