The standardization of categorizing voice tones by V7B

Abstract

Human voice tones are produced at various fundamental frequencies according to the gender and age of the speaker as well as the production environment. Even the voice tones with the same pitch are recognized differently depending on whether people are speaking or singing. Yet the standardized system categorizing voice tones into certain objective types is currently not available. It is undeniable that voice tones are still expressed in rather confusing terms and unsystematic ways, and thus invokes an urgent need for the standardization of categorizing voice tones. This thesis proposes V7B (for Voice 7 Bandwidth), the standardized system for categorizing any human voice tones produced within the maximum range of frequencies. V7B can be utilized in 2 different bands, narrow and wide, depending on the voice production environment, speaking or singing. V7B categorizes voice tones into 7 levels with equal ranges of frequencies, such as 'extremely low tone,' 'low tone,' 'mid-low tone,' 'mid tone,' 'mid-high tone,' 'high tone,' and 'extremely high tone.' V7B provides an objective and systematic way to describe human voice tones properly based on human intuitions. © 2012 Springer-Verlag.
