Deep Voice Generator
Turn any sentence into a slow, low, gravelly delivery, the kind that makes a dull announcement sound like a movie trailer.
How the deep sound is made
The speech model is asked for a low, slow, gravelly reading. Your browser then slows the clip by about 20 percent, which drops the pitch, and adds a gentle boost to the low end around 220 Hz so the voice gets chest and weight.
This is an effect on a normal voice. It does not turn a high voice into a specific famous one, and it will not sound like any named narrator.
Writing lines that work
Deep voices are for gravity. Give it a small, silly subject and a huge tone: "In a world where nobody refills the printer paper, one man stood up." Keep sentences under about twenty words, and put full stops where you want a pause.
Avoid long strings of numbers or abbreviations. Low voices make mispronunciations more obvious.
Where people use it
Mock movie trailers, narrating a pet or a roommate, a dramatic announcement in a group chat, game-night intros, school videos that need a serious narrator, and meme edits.
What it will not do
It will not imitate any real narrator, actor or celebrity, and prompts that name one are refused. It also will not make a believable voice for impersonating someone you know. See the Disclaimer.
Example lines to try
These lines were written for this style and tend to sound right straight away:
- "This summer, one sandwich will change everything."
- "You have reached the voicemail of someone who is probably napping."
- "Tonight on the news: the dishwasher is still not empty."
- "And so the hero looked at the stairs, and the stairs looked back."
Quick fixes if it sounds wrong
If the clip drags, cut the line to one sentence. If the low end is muddy on phone speakers, play it on headphones first; phone speakers do not reproduce deep bass, so the voice can sound thinner there than in the download.
Commas add small pauses, which gives you the slow trailer rhythm: "In a world, where nobody, refills the printer." Write numbers and abbreviations out as words, such as "three hundred" instead of "300", so you decide exactly how they are read. One strong sentence usually works better than three average ones.
Using the clip in your project
The download is a WAV file that works in any editor. For a mock trailer, lay the clip over slow music and add a hit or a rumble just before the key word. For a voicemail greeting, keep it under ten seconds and make the last line the joke. On a phone, test the clip on the speaker you expect people to use, since small speakers hide low frequencies and the voice may sound lighter than it does on headphones.
Frequently asked questions
Can I make my own voice deeper?
This tool does not take recordings. It only reads typed text. To change a recording of your own voice you need a voice changer app.
Why does the deep voice sound slow?
Lowering pitch with this method also slows the clip. That slowness is part of the weight. Shorter lines keep it from dragging.
What is the longest line I can use?
200 characters, roughly one or two sentences.
