摘　　要：该文提出一种改进的在基于Bloomfield模型语音检测算法，该方法引入数值滤波器克服了BF模型固有的缺陷。通过实验分析表明，该方法与传统方法相比，提高了基音周期提取的准确性和分辨率，增强了清浊音判决的可靠性。A Modified Approach of Pitch Detection Based on Bloomfield Model was proposed in this paper, and it introduced numerical filter to overcome the inherent flaws of the BF model. The experimental analysis show that the new method has better than that of conventional approach, it may provides a higher accuracy and resolution in speech detection, and improve the reliability of voiced/unvoiced decisions.
