Record a line or upload a clip, and the deep voice changer drops it four and a half semitones and adds low-end warmth, so you sound bigger without sounding fake. Compare it with your original, then download a WAV. Free, in your browser.
How it works
Three steps, no software. Speak at your normal pitch and let the effect do the lowering.
Step 1
Press Record and talk for up to 60 seconds, or upload an MP3, WAV, M4A or OGG file up to 20 MB and 5 minutes long. Use your normal speaking voice; pushing it low before the effect tends to sound strained afterwards.
Step 2
Deep voice is preselected, so press Apply effect and your browser renders the clip in a few seconds. Want it lower and rougher? Tap Monster to hear the same take seven semitones down with a growl.
Step 3
Switch between Original and Deep voice mid-playback to hear both at the same moment. When it sounds right, download deep-voice.wav, a mono WAV that opens in any editor.
Scripts to try
Slow, confident lines with long vowels show off depth best. Read one aloud when you press Record.
In a world where nobody reads the manual... one man reads it twice.
Pause at the dots. Silence makes a deep voice sound bigger.
Good evening, and welcome back. Get comfortable, pour something warm, and let's begin.
You've reached Marcus. I can't take your call right now, so leave a message and I'll call you back.
The gates are closed. The torches are lit. Only the brave go further.
Ladies and gentlemen... the moment you have all been waiting for... starts now.
Stretch the vowels in 'waiting' and 'now'.
Highlights
The effect changes two things, pitch and warmth, and leaves your timing, accent and delivery alone.
Your voice is lowered by 4.5 semitones, which cuts every frequency by roughly 23%. A man speaking around 120 Hz comes out near 93 Hz, and a woman around 210 Hz lands near 162 Hz. The clip keeps its length, so it still lines up with your video.
A low shelf adds about 5 dB below 150 Hz, the chesty region late-night radio hosts are known for, and the very top above 7 kHz is eased back 2 dB. The result sounds full and smooth rather than boomy or hissy.
Pitch shifting moves the resonances of your mouth and throat along with the pitch. Push it too far and a person starts to sound like a giant. 4.5 semitones is about as low as it goes while still sounding human; for the full beast, try the monster voice changer.
Quick reference
Typical speaking pitch before and after the effect. Your own result depends on where your voice sits today.
| Speaker | Typical pitch | After the effect |
|---|---|---|
| Man, higher voice | 150 Hz | ≈ 116 Hz |
| Man, average voice | 120 Hz | ≈ 93 Hz |
| Man, already deep | 100 Hz | ≈ 77 Hz |
| Woman, lower voice | 170 Hz | ≈ 131 Hz |
| Woman, average voice | 210 Hz | ≈ 162 Hz |
| Child | 300 Hz | ≈ 231 Hz |
Adult men usually speak around 85–155 Hz and women around 165–255 Hz. To find your own starting point, the deep voice test measures your speaking pitch in Hz.
Two things make a voice sound deep. Pitch is how fast your vocal folds vibrate, and resonance is how your throat and mouth color that buzz. Larger bodies usually have both lower, so listeners hear the combination as a bigger, calmer speaker. This effect lowers both together, which is why you sound like a larger version of yourself rather than a slowed-down tape.
It has limits. A pitch shift can't add the rasp, breath control or relaxed chest resonance of a trained deep voice, and very low settings start to sound boxy, which is why this one stops at 4.5 semitones. A typical female voice lands around 160 Hz, which reads as low and androgynous rather than clearly male.
If you want your real voice to sound deeper, posture, breath support and a slower pace all help over time. The guide on how to make your voice deeper walks through safe exercises.
Mind the rumble. Unlike most effects here, deep voice has no low-cut filter, and its shelf boosts everything under 150 Hz. Air conditioners, traffic and a bumped desk get louder along with your voice, so record in a quiet room and keep the phone off the table you're tapping.
Use a little proximity. Headset and desk mics pick up extra bass when you're close, a natural boost called the proximity effect. About 4 to 6 inches (10–15 cm) works well. Angle the mic slightly to the side so P and B sounds don't thump, because the bass boost exaggerates pops.
Slow down. Deep voices sound confident because they take their time. Speak a touch slower than usual, let sentences fall in pitch at the end, and relax your jaw instead of pressing down on your throat. Forced low notes add vocal fry, which turns gravelly after the shift.
Rather type? The deep voice generator creates a deep AI voice from text; it needs a free account and uses credits. This changer is free and keeps your own words, accent and timing. Either way, a deeper voice is for videos, characters and fun, not for passing yourself off as someone else.
