There are exercises you can use to make your voice deeper:
Take deep breaths and make a hissing sound as you exhale. After you take a big breath in, grit your teeth and slowly release the air in your lungs to make a hissing sound. This will really open up your chest and make your voice lower before you speak.

Open your mouth as wide as you can and try to yawn. This movement will force your larynx downwards in your throat and make your voice lower in tone. Repeat this 4 or 5 times before you talk, but don't force the yawn too hard because this could hurt your vocal cords.

Resonate from your chest. To do this, you'll want to take a big breath and then hum for as long as you can while holding it in. Humming will warm up and stretch your vocal cords, which lowers the voice.
