In March 2008, Ameya/Ayame released a free, advanced support tool to aid a 'Manual VOCALOID' process, called UTAU. This beta software can still be downloaded from Ameya/Ayame's website. It features a simple interface with a piano roll, has limited mora (Japanese syllables) and works with a primitive beta engine (or 'resampler') later updated on UTAU. In December 2007, Ameya/Ayame ( 飴 ( あめ ) 屋 ( や )／菖蒲 ( あやめ )), using LOLI.COM's voice samples, released a beta software called Loliedit featuring a simple voicebank called 'Loline Com' (a pun on the original voice provider and the 'ne' particle originally used on Crypton's products). UTAU, meaning 'to sing' in Japanese, has its origin in 'Jinriki VOCALOID' (人力ボーカロイド, 'Manual VOCALOID'), the act of re-editing an existing singing voice, extracting tones as WAV files, and reassembling them. Some users have also began to enforce their copyright ruling over their voicebanks UTAU or fanmade VOCALOIDs who are guilty of plagiarizing an UTAU's name or using a voicebank without permission risk violating UTAU software agreements and voicebank copyright ownership. Songs using both UTAU and VOCALOID are also not unheard of. Some UTAU voicebanks have been put out as 'real' VOCALOIDs, such as the April Fool's joke origins of Kasane Teto.

Therefore the plug-ins for UTAU can often prove invaluable to users as they can effect the software's results and quality greatly.

This support was established fairly early in the software's existence, whereas VOCALOID did not gain this ability until VOCALOID3 in late 2011 and even now it only offers a limited access to source code and plug-in support. It has plug-in support and users have made a number of plug-ins that greatly improve the software's handling and experience. UTAU has the advantage of having its development occur at a faster pace.

And is viewed as a well-supported alternative to more expensive software that share the same abilities. UTAU is a shareware vocal synthesizer program that allows users to create and distribute their own voicebanks. Vocal Synthesis Tool UTAU ( 歌 ( うた ) 声 ( ごえ ) 合 ( ごう ) 成 ( せい )ツール UTAU) is a voice synthesizer program currently available for Windows and Mac OS X systems (the Mac version being named UTAU-Synth), it was developed by Ameya/Ayame.
