More about this voice

Small robot, small speaker

Part	Setting	What you hear
Size	Pitch +6, Tone +4	A tiny, high voice
Buzz	Robot 180 Hz, 50% mix	A bright electric hum mixed equally with the voice
Cheap chip	Bit crusher 8-bit at 11.0 kHz, 60% mix	Crunchy, toy-grade sound
Tiny speaker	Bass cut below 350 Hz, treble cut above 5 kHz	No low end at all, like a speaker the size of a coin

Act like a wind-up toy

Use very short phrases of two to four words, the kind a toy says when a button is pressed.
Keep a bouncy, even rhythm, one beat per syllable.
Sound cheerful about everything, including bad news.
Repeat a phrase exactly the same way twice. Toys have a small set of lines, and the repetition sells it.

Batteries running out	Pitch +2 with a slow wobble, 0.6 times a second at 60%	A drooping, seasick voice for a sad or comic ending

Free toy robot voice changer FAQ

Is it good for kids' videos?

Yes. It is light and friendly, not scary. Record lines in the Online Voice Changer and download them for the edit.

Can I use the toy robot voice on my phone?

The live version runs in Chrome on a computer only. You can still make clips on a computer and move the downloaded files to your phone.

How do I make it sound like the batteries are dying?

Load the second clip: Pitch falls to +2 and a slow wobble makes the voice sag. Speak slower yourself as well, because the effect doesn't change your speed.
