About the Rimuru Tempest voice

Rimuru Tempest is the main character of That Time I Got Reincarnated as a Slime, a fantasy story that began as a web novel and grew into a light novel series, a manga and a popular anime. An ordinary office worker dies and is reborn in another world as a slime. With the abilities Rimuru gains there, they befriend monsters, build a thriving nation and become a leader others look to for protection.

The voice is warm, calm and friendly. It sits in a soft, mid-to-high range that feels approachable rather than sharp. The pace is relaxed and conversational, and the delivery is easygoing, with a gentle sense of humor. When the moment calls for it, the tone can turn firm and commanding, but it always keeps a kind, steady character. Expect a smooth, youthful sound that suits friendly chat and light storytelling.

On voicechange.io, you can record or upload speech and hear it transformed into this voice. You can also type text to have it spoken, or make a song cover. The pitch is matched to the voice automatically, so you don't need to adjust it yourself. For the best results, speak clearly in a quiet room and keep a relaxed, friendly pace. Natural, laid-back delivery fits Rimuru best, and short phrases are a great way to start.

Voice details

Tips for the best Rimuru Tempest result

This model is centred around 250 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 Rimuru Tempest 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.
