Timing adjustment In singing voices, the consonant onset of a syllable is uttered before the vowel onset is uttered. When Vocaloid runs as VSTi accessible from DAW, the bundled VST plug-in bypasses the Score Editor and directly sends these messages to the Synthesis Engine. The Synthesis Engine receives score information contained in dedicated MIDI messages called Vocaloid MIDI sent by the Score Editor, adjusts pitch and timbre of the selected samples in frequency domain, and splices them to synthesize singing voices. Due to this linguisticĭifference, a Japanese library is not suitable for singing in English. Thus, more diphones need to be recorded into anĮnglish library than into a Japanese one. On the other hand, English has many closed syllablesĮnding in a consonant, and consonant-consonant and consonant-voicelessĭiphones as well. In Japanese, there are basically three patterns of diphones containing a consonant: voiceless-consonant, vowel-consonant, and consonant-vowel. Japanese has fewer diphones because it has fewer phonemes and most syllabic sounds are open syllables ending in a vowel. Japanese requires 500 diphones per pitch, whereas English requires 2,500. Natural sounds, three or four different pitch ranges are required to be Of these fragments so that it fits the melody. N-#" (# indicating a voiceless phoneme) with the sustained vowel ī. Synthesized by concatenating the sequence of diphones "#-s, s-I, I-N, The database must have all possible combinations of phonemes of the target language, including diphones (a chain of two different phonemes) and sustained vowels, as well as polyphones with more than two phonemes if necessary.įor example, the voice corresponding to the word "sing" () can be
They cannot naturally replicate singing expressions like hoarse voices or shouts, either.Įach Vocaloid licensee develops the Singer Library, or a database of vocal fragments sampled from real people. The Vocaloid and Vocaloid 2 synthesis enginesĪre designed for singing, not reading text aloud. Is explained as "vocal expressions" such as vibrato and vocal fragments The Vocaloid synthesis technology was initiallyĬalled "Frequency-domain Singing Articulation Splicing and Shaping" although Yamaha no longer uses this name on its websites. In singing synthesis, the system produces realistic voices by adding information of vocal expressions like vibrato to score information. TechnologyThe Vocaloid singing synthesizer technology is categorized as concatenative synthesis, which splices and processes vocal fragments extracted from human singing voices in the frequency domain. Artists such as Mike Oldfield have also used Vocaloids within their work for back up singer vocals and sound samples. also have released compilation albums featuring Vocaloids. Japanese record label Exit Tunes of Quake Inc. Japanese musical groups Livetune of Victor Entertainment and Supercell of Sony Music Entertainment Japan have released their songs featuring Vocaloid as vocals.

The software is intended for professional musicians as well as lightĬomputer music users and has so far sold on the idea that the only The software was originally only available in English and Japanese, but as of Vocaloid 3, Spanish, Chinese and Korean have been added. Each Vocaloid is sold as "a singer in a box" designed to act as a replacement for an actual singer. The software can change the stress of the pronunciations, add effects such as vibrato, or change the dynamics and tone of the voice. A piano roll type interface is used to input the melody and the lyrics can be entered on each note. To create a song, the user must input the melody and lyrics. It uses synthesizing technology with specially recorded vocals of voice actors or singers. The software enables users to synthesize singing by typing in lyrics and melody. Backed by the Yamaha Corporation it developed the software into the commercial product "Vocaloid".

Its signal processing part was developed through a joint research project led by Kenmochi Hideki at the Pompeu Fabra University in Spain in 2000 and originally was not intended to be a full commercial project.
