is a singing voice synthesizer. Its signal processing part was developed through a joint research project led by Kenmochi Hideki at the Pompeu Fabra University in Barcelona, Catalonia, Spain, in 2000 (the same team that later founded Voctro Labs〔 (【引用サイトリンク】 url = http://www.voctrolabs.com ) 〕) and originally was not intended to be a full commercial project. Backed by the Yamaha Corporation, it developed the software into the commercial product "Vocaloid".〔 〕 The software enables users to synthesize singing by typing in lyrics and melody. It uses synthesizing technology with specially recorded vocals of voice actors or singers. To create a song, the user must input the melody and lyrics. A piano roll type interface is used to input the melody and the lyrics can be entered on each note. The software can change the stress of the pronunciations, add effects such as vibrato, or change the dynamics and tone of the voice. Each Vocaloid is sold as "a singer in a box" designed to act as a replacement for an actual singer. The software was originally only available in English starting with the first Vocaloids Leon, Lola and Miriam and Japanese with Meiko and Kaito, but Vocaloid 3 has added support for Spanish for the Vocaloids Bruno, Clara and Maika; Chinese for Luo Tianyi and Yanhe; Korean for SeeU. The software is intended for professional musicians as well as light computer music users and has so far sold on the idea that the only limits are the users' own skills.〔 〕 Japanese musical groups Livetune of Toy's Factory and Supercell of Sony Music Entertainment Japan have released their songs featuring Vocaloid as vocals. Japanese record label Exit Tunes of Quake Inc. also have released compilation albums featuring Vocaloids.〔 〕〔 〕 Artists such as Mike Oldfield have also used Vocaloids within their work for back up singer vocals and sound samples.〔 (【引用サイトリンク】 url = http://www.zero-g.co.uk/index.cfm?articleid=805 ) 〕〔 ==Technology== The Vocaloid singing synthesizer technology is categorized as concatenative synthesis, which splices and processes vocal fragments extracted from human singing voices in the frequency domain. In singing synthesis, the system produces realistic voices by adding information of vocal expressions like vibrato to score information.〔 〕 The Vocaloid synthesis technology was initially called ,〔 〕 although Yamaha no longer uses this name on its websites.〔 〕 "Singing Articulation" is explained as "vocal expressions" such as vibrato and vocal fragments necessary for singing. The Vocaloid and Vocaloid 2 synthesis engines are designed for singing, not reading text aloud,〔 〕 though software such as Vocaloid-flex and Voiceroid have been developed for that. They cannot naturally replicate singing expressions like hoarse voices or shouts. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vocaloid」の詳細全文を読む スポンサード リンク
