Voice Timbre Evaluation of Broadcast Host Based on Extraction of Voice Feature Parameters

Abstract

The continuous development of science and technology has continuously improved people's quality of life. People's definition of health is also clearer, and more attention is paid to laryngeal diseases and the quality of voice. In real life, accurate evaluation of voice quality and timbre is not only beneficial to the diagnosis and treatment of laryngeal diseases. At the same time, it also plays a vital role in the selection and training of broadcasting and hosting talents. The current evaluation methods for related professional voices have shortcomings such as time-consuming, labor-intensive and highly subjective. In order to overcome these defects and explore how to help the training of broadcast hosts, this paper conducts in-depth research on the processing method of speech signals and the objective evaluation method of artistic voice timbre from the perspective of signal processing. Through experimental analysis, it is found that the objective evaluation method of voice timbre based on acoustic parameters F0, F1, F3 can better realize the objective evaluation of the voice timbre of the broadcast host. Among them, the accuracy rate of the evaluation method based on multiple feature parameter extraction reaches 89.2%.
