Is There a Pill or Something That Makes Your Voice Deeper Permanently?

Unless you're speaking voice is uncomfortably high for you, the most likely thing is that it's unhealthy to continuously deepen your voice for anything permanent. Artificially making your voice sound deeper by shifting some things physiologically in your throat is possible, but from a general health standpoint, it's not possible to do so permanently without medical intervention. This intervention may not be worth it.

There is a medical procedure called Thyroplasty. It is done by a head/neck medical specialist. The procedure is pretty straightforward. They create slack in your vocal cords by pushing in the cricoid cartilage in your throat. Your voice thickens and deepens. I had it done because I was tired of people calling me "Miss" and "Ma'am" on the phone when I'm a guy. Also, as an actor, it cut into the type of work I could get. It only took a day to recover, but the swelling affected my voice for a few months. It was one of the best decisions I ever made. I am still thinking about a second procedure where they place a small piece of plastic next to the cords to create a stronger voice and glottal stop. Note: Reading the other comments it amazes me how many people put in their two cents without knowing what the hell they’re talking about. Next time, ask a doctor who specializes in vocal cords. The doctor I saw was at U.C.L.A. Dr. Berke.

No Such Thing Exists

There is no such thing as a pill or other substance that can make your voice permanently deeper. In fact, there is nothing that can be done to permanently change one's vocal cords. The vocal cords are genetic. Natural methods to make your voice deeper, such as performing the humming exercise, may help, but they do not result in a permanent change.

Humming Exercise to Deepen Your Voice Naturally

You can naturally make your voice deeper than it currently is by performing the humming exercise or going to a voice therapist. The exercise involves the following steps:

Place the tip of your tongue behind your bottom front teeth. Hum up and down the major scale while keeping your mouth closed. This will strengthen and stretch your neck from the inside, allowing air to flow more easily and produce a deeper sound coming out of your mouth.

Note: Voice deepening surgery, if you look it up on YouTube, can reveal people who have gone through it for both lowering or raising their pitch.

Remember, any attempt to permanently change your voice through non-medical methods or surgery can come with risks and may not be reversible. If you are considering any kind of medical intervention, it's crucial to consult with a vocal cord specialist to understand the potential benefits and risks associated with the procedure.
