Voice Changer.io

Voice Changer.ioとは？

Voice Changer.io is a free online audio tool for applying sound and voice effects to an audio clip. Users can upload or drag and drop an audio file, record through a microphone, or generate speech from text, then play or download the processed result. Its effects range from pitch and speed changes to distortion, echo, reversal, and character-style voices. The site describes the tool as a hobby project and cautions that its anonymous-sounding effect is for fun, not real anonymization.

Voice Changer.ioでできること

Multiple audio inputs

Start with an uploaded or drag-and-dropped audio file, record using a microphone, or generate speech from text.

Character and synthetic voice effects

Apply effects designed for monster, demon, alien, robot, Dalek, or anonymous-sounding voices.

Room and environment echoes

Choose effects such as cave echo, large-room echo, or reverse reverb for spatial or eerie sound.

Signal and lo-fi treatments

Use telephone filtering, old-radio fuzz, PA-speaker distortion, or cymbal-like convolution effects.

After processing, play the result or download the transformed audio.

利用シーン

“Create character dialogue”

Record or generate a line, then use a monster, demon, alien, or robot effect for a performance, game session, or skit.

“Prepare a short audio gag”

Transform a spoken clip with reversal, speed changes, wobble, or a computer-like voice and download the result.

“Add atmosphere to a scene”

Use cave echo, reverse reverb, or a distorted PA treatment to give dialogue a setting-specific sound.

“Preview a voice treatment from text”

Generate speech from text and apply an effect when a microphone or prerecorded clip is not the preferred starting point.

よくある質問

What can I use as the audio input?

The page offers audio upload, microphone recording, and speech generation from text. It also supports dragging an audio file onto the page.

Can I save the processed audio?

Yes. The site says processed audio can be played or downloaded.

Does the anonymous effect make my voice truly anonymous?

No. The site explicitly says the anonymous-sounding effect is for fun and should not be used for real anonymization.

Can I use it as a real-time voice changer in other apps?

The browser tool processes audio clips that you upload, record or generate. Do not assume it provides a live microphone voice changer inside other applications or games; check the current description of any separate tool for that workflow.
