UTAU is a free Japanese vocal synthesizer that people can use to make "voicebanks" sing or talk. People can create their own, and it's actually quite simple. Here's how:


  • 1. If you haven't changed your system locale to Japanese, do this now. Go under "Clocks, Language, and Region" in your Control Panel. Choose "Region and Language". Click on the tab "Administrative". There should be a button "Change System Locale."
  • 2. Open Audacity.
  • 3. Using your microphone, record yourself saying "a". Hold the note at an even tone and volume for about 2 seconds.
  • 4. If it came out quieter than you expected, choose Amplify under Effects to make it louder.
  • 5. Choose Fade In under Effects.
  • 6. Choose Fade Out under Effects.
  • 7. Amplify again. Now the sound should sound smoother.
  • 8. Create a new folder with the name of your UTAU voicebank.
  • 9. Save "a" as a WAV file in that folder, either as "a" (romaji) or "あ" (hiragana).
  • 10. Repeat steps 1-10 for each syllable you want to record. In order for your UTAU to sing basic Japanese, you will need to record at least 45 syllables.
  • 11. Open UTAU.
  • 12. Click (T).
  • 13. Click (O). This will open a menu.
  • 14. Click the second menu tab. You should see all of the UTAU voicebanks you have and where you have them stored.
  • 15. Click the button next to the long bar to type things in. This should bring up Windows Explorer.
  • 16. Find the file you saved "a" in.
  • 17. Choose "a" and click open.
  • 18. Click OK. You now have your voicebank installed in UTAU.
