本发明提出了一种基于移动终端的个性化均衡器，用于改善尤其是老年人的人类语音的听觉能力。实验结果表明，该均衡器能有效地提高语音识别成功率的2%~ 55%。根据频率分量分析和共振峰检测的研究，大多数语音声音具有在3445 Hz范围内的第一至第三频率的共振峰频率。因此，非线性均衡乘法器尤其更好地增强第一到第三共振峰的频率分量。上述语音输入实验的结果表明，对于0到8000 Hz以上的频率成分，需要良好的正确识别率：PCR。此外，8162 Hz的截止频率对于噪声抑制和保持良好的PCR都更好
Mobile device based personalized equalizer for improving the hearing capability of human voices in particular for elderly persons are proposed. Through experiments, it is found that the proposed equalizer does work well for improving hearing capability by 2 to 55 % of voice Recognition success ratio. According to the investigation of the frequency component analysis and formant detections, most of the voice sounds have the formant frequencies for the first to third frequencies within the range of 3445 Hz. Therefore, a nonlinear equalizing multiplier is better to enhance the frequency components for the first to third formants in particular. The experimental results with the voice above input experiments show that a good Percent Correct Recognition: PCR is required for 0 to more than 8000 Hz of frequency components. Also, 8162 Hz cut off frequency would be better for both noise suppressions and keeping a good PCR
