How to Get a Deeper Voice: What Actually Works, What’s Myth
Can you actually make your voice deeper, or is it fixed the day puberty finishes? The honest answer sits between those two extremes, and most of what teenage boys are told about it, raw eggs included, has nothing to do with how a voice box actually works.

What actually determines how deep a voice is
Voice pitch comes down largely to the size and thickness of the vocal cords (also called vocal folds) inside the larynx, or voice box. Longer, thicker cords vibrate more slowly, producing a lower pitch, similar to how a thicker guitar string produces a deeper note than a thin one. During male puberty, testosterone causes the larynx to grow and the cords to thicken, usually finishing the main change between roughly 13 and 17, though the exact timing varies a lot person to person. Once that growth is complete, the anatomical baseline pitch of your voice is largely set.
A voice box finishes growing the way feet stop growing. After that, what changes is how you use it, not its size.
What genuinely helps, within that anatomical limit
- Hydration: drink water through the day, aiming for pale yellow urine as a rough guide, since dry vocal cords vibrate less smoothly and can sound thinner or strained.
- Posture and breath support: stand or sit upright, breathe from the diaphragm (belly expands on inhale, not just the chest), and speak from that supported breath rather than a shallow, throat-only voice. This often reveals a fuller, slightly lower resonance that was already there but got lost in a tense, shallow speaking habit.
- Relax the throat and jaw: a tense jaw and throat push the voice higher and thinner. Gently massage the jaw hinge for 30 seconds before speaking in situations where you tend to tense up, like presentations.
- Practice speaking from your chest, not your nose or throat: place a hand flat on your upper chest while talking normally, then try to feel a slight vibration there rather than only in your nose or throat. This is resonance training, used by voice coaches, and it genuinely changes perceived depth without changing the cords themselves.
- Rest your voice when hoarse: shouting, whispering harshly, or talking for hours when hoarse can strain the cords and temporarily make the voice sound rougher or higher when it’s tired, not deeper.
Myth: raw eggs deepen the voice
This one circulates widely, often tied to old bodybuilder folklore about raw eggs and testosterone. There is no mechanism by which drinking raw eggs changes vocal cord thickness or larynx size. Raw eggs also carry a real salmonella risk and offer no advantage over cooked eggs nutritionally. Skip this one entirely; it does nothing for the voice and adds a food safety risk for no benefit.
Myth: smoking or shouting deepens the voice permanently
Smoking can make a voice sound rougher and lower over years, but that’s from chronic irritation and, eventually, damage to the vocal cords, not a healthy deepening. The same applies to habitually shouting or straining the voice: the roughness some people mistake for a “deeper” voice is often vocal cord swelling or, in serious long-term cases, polyps or nodules, which are medical problems, not a desirable trait. If your voice sounds different after shouting a lot and doesn’t recover within a few days of rest, that’s worth a doctor’s or ENT’s attention, not something to chase deliberately.
Myth: certain foods or gargles change vocal cord size
Ajwain water, ginger tea, warm milk with turmeric, none of these change the physical size of the vocal cords, ever, regardless of how consistently they’re used. Warm fluids can soothe an irritated throat and make speaking more comfortable when you’re hoarse, which indirectly lets your natural voice come through more clearly instead of a strained, thinner sound. That’s a real, if modest, benefit. It is not the same as a voice becoming structurally deeper.
What voice actors and singers actually train, and why it’s relevant here
Professional voice coaches distinguish between pitch, which is largely fixed by cord anatomy, and resonance, timbre and projection, which are trainable skills. A trained speaker sounds deeper and fuller not because their cords changed but because they’ve learned to use the resonating spaces of the throat, mouth and chest efficiently, the same idea behind the chest-vibration exercise described above. This is genuinely useful information for a teenager frustrated that puberty hasn’t given them the voice they expected, because it separates what’s biologically out of their control from what a few weeks of deliberate practice can actually shift. It’s also why two men with similarly sized larynxes can sound noticeably different when speaking; one has simply learned to use breath and resonance better than the other, often without any formal training at all.
Warm-up matters too. Singers and broadcasters commonly do 5 minutes of humming, starting low and sliding gently upward, before demanding vocal work, and this loosens tension in the same way stretching loosens a tight muscle before exercise. Skipping this and speaking cold, especially first thing in the morning when cords are naturally a little swollen from sleep, tends to produce a thinner, more strained sound than a warmed-up voice.
Unani tradition associates the throat and voice with balgham (phlegm) and advises warm, drying foods like honey and ginger to clear excess moisture thought to muffle the voice. As a traditional idea about comfort and clarity of speech when hoarse from a cold, it holds up reasonably as folk wisdom. It was never framed, even traditionally, as permanently altering pitch.
See a doctor or ENT specialist if hoarseness lasts more than 2 to 3 weeks without a clear cause like a cold, if your voice suddenly and persistently drops or changes without an obvious reason, or if you have pain, difficulty swallowing, or a lump you can feel in the neck alongside voice changes. Persistent voice change can occasionally signal something needing medical attention, and it’s not something to self-treat with home remedies while waiting it out for months.
What delayed puberty and voice concerns actually have in common
Occasionally a teenager’s worry about voice depth is really a worry about delayed puberty overall, since voice change is just one of several markers, alongside height growth spurts, facial hair and body changes, that typically cluster together in a rough sequence. If voice change hasn’t started at all by around 15, alongside an absence of other puberty signs, that’s a reasonable, non-alarming reason to mention it to a doctor, mainly to rule out a hormonal cause needing simple monitoring or, occasionally, treatment. This is different from a voice that has changed some but not as dramatically as a friend’s, which is well within normal individual variation and not something to chase with remedies at all.
Try this
Record yourself reading a paragraph aloud in your normal voice, then again after 30 seconds of the jaw and chest resonance exercises above. Most people notice a genuinely fuller, slightly lower sound on the second recording, simply from better breath support and less throat tension, not from anything having changed physically.
Frequently asked questions
Can voice training apps or exercises actually lower pitch permanently?
They can improve resonance and how a voice is used, which changes perceived depth, but they don’t alter vocal cord anatomy. Speech therapists who specialise in voice, sometimes used by trans men or trans women alongside hormone therapy, work with this same anatomical reality.
Does testosterone therapy in adulthood deepen the voice the way puberty does?
Yes, testosterone can thicken adult vocal cords too, which is why it’s used medically for voice change in some contexts, but that’s a supervised medical treatment, not a home remedy, and it comes with its own risks and monitoring needs.
Why does my voice crack or go higher when I’m nervous?
Nervousness tenses the throat and shortens breath support, both of which push the pitch up and can cause cracking. It’s a tension response, not a sign anything is wrong with the voice itself.
