Scope of Inclusion
CVSA contains many aspects of Chinese Vocal Synthesis, including songs, albums, artists (publisher, manipulators, arranger, etc), singers and voice engines / voicebanks.
For a song, it must meet the following conditions to be included in CVSA:
Category 30
In principle, the songs featured in CVSA must be included in a video categorized under VOCALOID·UTAU (ID 30) that is posted on Bilibili. In some special cases, this rule may not be enforced.
At Leats One Line of Chinese
The lyrics of the song must contain at least one line in Chinese. This means that even if a voicebank that only supports Chinese is used, if the lyrics of the song do not contain Chinese, it will not be included in the CVSA.
Using Vocal Synthesizer
To be included in CVSA, at least one line of the song must be produced by a Vocal Synthesizer (including harmony vocals).
We define a vocal synthesizer as a software or system that generates synthesized singing voices by algorithmically modeling vocal characteristics and producing audio from input parameters such as lyrics, pitch, and dynamics, encompassing both waveform-concatenation-based (e.g., VOCALOID, UTAU) and AI-based (e.g., Synthesizer V, ACE Studio) approaches, but excluding voice conversion tools that solely alter the timbre of pre-existing recordings (e.g., so-vits svc).
