| 摘 要： | 基音频率和共振峰频率的提取在语音编码、语音合成和语音识别中有着广泛的应用。通过深入分析语音信号的时域和频域性质,针对语音信号幅度谱的特征设计了一种有效的基频和共振峰提取算法。并对实际语音信号进行参数提取测试,实验结果证明了这种算法能够准确提取不同讲话者和录音条件下的语音信号的基频与共振峰频率。

| Abstract: | Extraction of fundamental frequency and Formants of a speech signal is a fundamental problem in speech coding,speech synthesis and speech recognition.An algorithm for the fundamental and formants extraction is designed in accordance with the future of speech spectrum.The algorithm is tested by reconstructing the speech signal using the value of fundamental frequency and formants which is extracted,and the result shows that the parameters' value is accuracy in diversified condition. |
