摘要
针对线性预测方法提取语音信号共振峰频率的不足,提出了一种基于共振峰增强的共振峰频率估计算法,从而在不增加运算量的情况下使共振峰频率的提取更加准确。实验结果表明,该算法在5kHz内提取前五个共振峰的性能都很好。
To overcome the weakness of the LPC method to estimate speech signal formant frequencies,a new extraction method based on formant enhancement is proposed. More formant frequencies can be accurately and efficiently determined with no computing complexity added. The experimental results show that this method achieves good performance in extracting the first five formant frequencies below 5kHz.
