UTAU

Vector software synthesizer for Windows that lets you create singing voices

Visit UTAU

UTAU is a vector software synthesizer for Windows that creates singing voices from recorded voice libraries. It can run as a standalone application or as a plugin, and it accepts both user-created voicebanks and third-party libraries, allowing music to be produced with different vocal timbres.

The software registers voicebanks as vector libraries, with pitch and other parameters editable in the interface. It is developed and tested for Windows environments, including Windows 10 Pro 22H2 and Windows XP Professional SP2, and is not available for Mac or Linux. The site also links to community resources such as UTAU Wiki and a user-created wiki.

Licensing notes cover music production, redistribution, and use of the UTAU name in commercial releases, with separate permissions required for voicebanks and audio output. Community participation is available through a Twitter account.
