A nasal-sounding voice happens when too much (or too little) air flows through your nose while you speak. The fix depends on which type of nasality you have and what’s causing it, but most people can reduce that “talking through your nose” quality with changes to tongue position, jaw openness, and a few targeted exercises.
Two Types of Nasality Sound Different
Most people searching for this assume their voice sounds stuffed up or whiny, but nasality actually comes in two opposite forms. Hypernasality means too much sound is escaping through your nose during speech. It gives your voice a buzzy, whiny quality, especially on vowels. Hyponasality is the opposite: not enough air passes through the nose, making you sound congested, like you have a permanent cold.
You can figure out which type you have with a simple test. Say a sentence that has no “m,” “n,” or “ng” sounds, something like “The bus took us to school.” While you say it, pinch your nose shut, then release, then pinch again. If your voice changes noticeably when you pinch, air is leaking through your nose when it shouldn’t be, and you have hypernasality. If it sounds the same either way, your nasality might be hyponasal, or your issue is more about resonance placement than actual airflow.
What Controls Airflow to Your Nose
A muscular valve at the back of your throat, called the velopharyngeal sphincter, acts as a gate between your mouth and nasal cavity. When you speak, your soft palate (the fleshy back portion of the roof of your mouth) lifts up and back while the walls of your throat squeeze inward. This seals off the nasal passage so that air and sound travel out through your mouth, where your tongue, lips, and teeth shape it into clear speech.
That seal is supposed to open for only three sounds in English: “m,” “n,” and “ng.” For every other sound, the gate should be closed. If it doesn’t close fully, air leaks into your nose on sounds that should be purely oral, and you get that characteristic nasal tone. If it closes too much or your nasal passages are physically blocked, you lose the resonance those three sounds need and everything sounds muffled.
How Tongue Position Creates Nasality
Your tongue plays a surprisingly large role. When the back of your tongue rides high in your mouth, it narrows the oral passage and pushes more sound energy up toward the nasal cavity. Research on vowel nasalization found that speakers who moved their tongue up and forward during certain sounds increased the “nasal shunt,” routing more acoustic energy through the nose even without meaning to.
The encouraging finding is that the reverse also works. In simulations where the velopharyngeal valve was left open (a setup that normally produces clearly nasal sound), researchers found that moving the tongue downward and forward was enough to produce speech that listeners perceived as non-nasal. In other words, even if your soft palate isn’t sealing perfectly, adjusting your tongue position can compensate and reduce the nasal quality others hear.
The practical takeaway: let your tongue rest low and slightly forward in your mouth when you speak. If you catch yourself with the back of your tongue bunched up toward your soft palate, consciously relax it downward. This opens up the oral cavity and keeps more sound resonating in your mouth rather than your nose.
Exercises That Strengthen the Soft Palate
If your soft palate is weak or sluggish, it won’t seal off the nasal passage quickly enough during speech. These exercises, used in NHS speech therapy programs, train the muscles that lift the palate and improve the seal.
- Yawning: A full, exaggerated yawn lifts the soft palate to its highest position. Practice deliberate yawns several times a day to build awareness of that lifting sensation.
- Cheek puffing: Puff your cheeks out with air, keep your lips sealed, and breathe through your nose. Press a finger against your inflated cheek. Don’t let air escape through your mouth or nose. Hold for 10 seconds. This builds pressure tolerance in the velopharyngeal valve.
- Straw blowing: Blow a steady stream of air through a straw. This forces the soft palate to close the nasal passage so all the air goes forward. Start with short bursts and work up to sustained blows of 10 to 15 seconds.
- Tongue-to-palate press: Place a spoon on the roof of your mouth behind your front teeth. Press the back of your tongue against the spoon’s edge and hold for 3 seconds. Repeat 5 times. This strengthens the tongue’s ability to create a good oral seal and builds coordination between the tongue and palate.
Do these daily for several weeks before expecting a noticeable change. Like any muscle training, consistency matters more than intensity.
Shift Your Resonance Forward
Many people who sound nasal are resonating sound in the back of their throat or high in their nasal passages rather than at the front of their face. Resonant voice therapy, a technique used by speech-language pathologists, trains you to direct vibrations toward your lips and the front of your mouth instead.
Start with humming. Sit or stand with relaxed posture, take a breath, and produce a gentle, easy hum. Focus on feeling the buzz in your lips and the front of your face rather than behind your nose. If you place your fingertips on your lips, you should feel them vibrate. Once you can consistently feel the vibration there, transition the hum into words: “hmmm-one, hmmm-two, hmmm-three,” carrying that forward placement into spoken sound.
Next, practice speaking short phrases while keeping that same forward focus. Imagine your voice projecting from your lips rather than from behind your nose. This feels subtle at first, but over time it retrains your default resonance placement. The goal is for speaking to feel effortless, with vibrations concentrated in the “mask” area of your face (lips, front teeth, hard palate) rather than the nasal cavity above.
Open Your Mouth More When You Speak
A tight, barely open jaw restricts the oral cavity and forces more sound through the nose by default. Dropping your jaw even slightly gives sound waves more room to resonate in your mouth, which shifts the balance away from nasal resonance.
Research on vocal resonance shows that varying jaw position changes which frequencies get amplified. Trained singers, for instance, deliberately adjust their jaw opening to boost oral resonance and project their voice more effectively. You don’t need to speak with an exaggerated open mouth, but if you tend to talk through nearly closed teeth, consciously relaxing your jaw will make a noticeable difference. Practice reading aloud in front of a mirror and watch whether your mouth opens enough to see your tongue moving. If it doesn’t, you’re restricting your oral space.
When the Cause Is Structural
Sometimes nasality isn’t a habit or muscle weakness problem. It’s a physical one. Hyponasality (sounding stuffed up) is commonly caused by a deviated septum, nasal polyps, chronically swollen turbinates, or enlarged adenoids. These block the nasal passages and prevent normal resonance on “m,” “n,” and “ng” sounds. If you always sound congested even when you don’t have a cold, an ENT specialist can evaluate whether obstruction is the issue.
Hypernasality can result from a soft palate that’s too short, a previously repaired cleft palate, or muscle weakness from neurological conditions. It can also appear after surgeries that remove tissue from the back of the throat, like tonsillectomy or adenoid removal, because the valve loses tissue it relied on for a complete seal. For structural causes of hypernasality, surgical correction is effective. The two most successful procedures improve nasal voice quality in roughly 85% of cases, though the right approach depends on the specific anatomy involved.
If exercises and technique adjustments don’t improve your nasality after a few months of consistent practice, the cause is more likely structural than behavioral. A speech-language pathologist can assess your velopharyngeal function using a thin scope passed through the nose to watch the valve in action, which pinpoints whether the problem is muscular control, tissue length, or obstruction.
