sidetone (redirected from Side tone)

sidetone

In a telephone handset, sending a small amount of your voice signal back into your ear through the handset so that you hear yourself talk. It makes the conversation more comfortable when you hear a little bit of your own speech, because you know the line isn't dead. See hybrid.
