Tails AI voice generator & voice changer

About the Tails voice

Miles "Tails" Prower is Sonic the Hedgehog's loyal two-tailed fox sidekick and a genius mechanic. Born with two tails that let him fly by spinning them like propellers, he looks up to Sonic and follows him on adventures. Tails is best known from the Sonic the Hedgehog video games, where he is a playable character and a gifted inventor who builds planes, gadgets and machines. He has also appeared in animated series, comics and the Sonic films.

The Tails voice is bright, youthful and friendly, with a higher pitch and a clear, energetic tone. Delivery is quick and eager, and it often sounds earnest, curious or a little nervous. When Tails explains an idea or a repair, the pace picks up with excitement. Expect a warm, boyish sound that suits upbeat lines, technical chatter and encouragement.

On voicechange.io you can record or upload speech and hear it come back as Tails, type text and have Tails speak it, or make a song cover. The pitch is matched to the voice automatically, so you don't need to adjust it. For the best results, use a clean recording with little background noise. For this voice, speak with plenty of energy and enthusiasm, at a lively pace, with clear emphasis. Try lines like a hopeful inventor explaining a new gadget.

Voice details

Tips for the best Tails 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 Tails 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.
