Music is a field that has an extensive influence on human beings and the natural world. People’s love for a good voice in the popular sense is inestimable. Today, with the development of science and technology, big data technology has been integrated into people's lives, and it has a wide audience in the field of singing. For example, China's most influential application products such as “Sing Ba” and “National K Song” have as many as 700 million users. Among these products, the popularity of the singing scoring system of the Chinese Academy of Sciences demonstrates people's appreciation for singing and the need for the cultivation and practice of high quality vocal music.
The artistic expression of the voice in opera, stage, film, television, and radio is referred to as artistic voice in the industry (Huang, 2022). There are diversities of styles and evaluation standards, but good voices with many popular styles must have something in common, and this commonality can be extracted as a popular evaluation standard for good voices. The traditional singing evaluation includes standard pitch lines. As long as the pitch of the user's singing is aligned with the pitch line, he can achieve high scores. At the same time, there is an evaluation system that seems to be a parallel world, that is, the evaluation of vocal music teachers or music critics. The evaluation criteria of singing include many aspects, such as air sinking, head cavity resonance, and accurate rhythm. The traditional singing voice evaluation standards are mostly judged by people, which are highly subjective and lack scientific explanation and objective evaluation standards. In addition, due to people's neglect of talent training in the field of singing, the influence of cognitive limitations and uselessness, the research and development of singing science is seriously restricted, resulting in a current lack of professional talent in the field of singing (Hao, 2021). According to the Chinese Music Industry Players Survey Report released in 2017, the talent shortage is one of the three biggest problems facing Chinese music start-up companies, but the cultural industry including the music field, is also affected by the current global economic downturn. As an industry that maintains a high rate of growth, music is the most important part of the cultural industry. Therefore, the cultivation of singing artists is imperative (Yang & Yue, 2020). The process of cultivating singing artists includes many aspects such as the selection of voice talents, voice guidance, singing training, and voice maintenance (Zhao & Jin, 2022). In view of the subjective limitations of the traditional singing voice evaluation process, it is hoped to scientifically define singing voice quality evaluation criteria by means of scientific research and establish a complete set of singing voice objective evaluation systems. The evaluation system further promotes the development of subjects such as vocal music education and voice medicine, as well as the cultivation of talents and the maintenance of voice (Syafitri et al., 2018).
