About the Hatsune Miku voice

Hatsune Miku is a virtual idol and Vocaloid character from Crypton Future Media, instantly recognizable by her long turquoise twin tails. She began as a singing voice synthesizer package and grew into a global pop culture figure, with songs and artwork created by a huge community of fans and producers. She performs at live concerts as a projected hologram-style character, appears in rhythm games, and has become a symbol of digital-age music making.

The voice is bright, clear and distinctly synthetic. Expect a high, youthful pitch with crisp consonants, a smooth and steady tone, and very precise timing. Delivery is clean and energetic rather than breathy or dramatic, with the slightly electronic sheen that makes Vocaloid music so recognizable. Spoken lines come out lively and melodic, and sung lines feel tight and polished.

On voicechange.io you can record or upload speech, type text to hear it spoken in this voice, or make a song cover. Pitch is matched to the voice automatically, so you don't need to adjust it yourself. For the best results, use a clean recording with little background noise and no echo. This voice shines on songs, so try an upbeat, melodic cover with clear lyrics and a steady rhythm. When speaking, keep a bright, energetic tone and pronounce each word clearly.

Voice details

Tips for the best Hatsune Miku 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 Hatsune Miku 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.
