About the Niffty voice
Niffty is a fictional character from Hazbin Hotel, the adult animated musical series about a hotel built to rehabilitate demons. She is the hotel's tiny, one-eyed cleaning demon, always scrubbing, dusting and tidying at breakneck speed. Cheerful, quirky and wildly energetic, she is also surprisingly dark and mischievous, which makes her a fan favorite among the hotel's staff and guests.
The voice is bright, high-pitched and bubbly, with a sing-song quality that bounces up and down as she talks. Her pace is fast and breathless, with sentences tumbling out in an excited rush. Delivery is sweet and chipper on the surface, with a playful, slightly unhinged edge that can slip in without warning. Expect lots of enthusiasm, quick reactions and a cartoonish, high-energy feel.
To get good results on voicechange.io, you can record or upload speech to transform it, type text to hear it spoken in this voice, or make a song cover. The pitch is matched to the voice automatically, so you don't need to adjust it yourself. For this voice, speak with plenty of energy and a lively, upbeat tone, and keep your pacing quick. Clear audio with little background noise helps too. Short, punchy lines full of excitement tend to sound the most like Niffty.

Tips for the best Niffty result
This model is centred around 260 Hz. With auto pitch on, a typical deeper voice (around 120 Hz) is shifted a full octave up (the maximum), and a typical higher voice (around 210 Hz) isn't shifted, since it already fits. Gaps under 4 semitones are left alone, and shifts stop at one octave. If the result sounds strained, nudge the slider one or two steps back toward your own voice; for song covers, keep it at 0, +12 or −12 so the vocal stays in key. How pitch works.
- Record in a quiet room with no music in the background; noise is the main cause of robotic-sounding results.
- Perform the line the way Niffty would say it. The model copies your timing and emotion, only the voice changes.
- For song covers, pick a track with one clear lead vocal and little reverb.
