Creepy voice generator

Make a creepy voice in three steps

1. Press Start recording or upload a voice clip or a video with speech.
2. Choose Creepy, Horror, or Deep machine.
3. Press Create voice, listen, and download. Try recording a whisper for the scariest result.

What makes a voice sound scary

Three ingredients do most of the work. Lower pitch makes a voice seem larger and less human. A slow tremble in volume, around 3 to 6 beats per second, mimics a shaky breath. A short echo makes the voice seem to come from an empty hall. Remove high frequencies and the voice loses its crispness, which makes it sound distant. The Creepy and Horror presets combine all four in different proportions.

Which preset to pick

Creepy is a lighter effect that keeps words intelligible, good for pranks, Halloween videos, and story narration. Horror drops the voice further and slows it, with a long echo that suits monster dialogue, analog-horror style narration, and game characters. Because pitch and speed change together, a clip becomes longer: a ten-second recording becomes about fourteen seconds at Horror. For video input, timing is kept so the picture stays in sync, and the pitch effect is lighter.

Record for the best effect

A clear, close recording gives the cleanest result. Whisper or speak slowly, and leave a moment of silence at the end so the echo has room to fade. Avoid recording in a noisy room, because the effect enhances noise as well as voice. Try writing a short script, such as a warning or a nursery rhyme, and perform it quietly.
