摘要
通过分析由32人录制的143段汉语耳语语段的耳语频谱,发现同一人的耳语频谱之间的差异远小于不同人的耳语频谱之间的差异。基于此提出了一种通过比较耳语语段的耳语频谱差异,可用于话者识别的方法,并通过实验验证了该方法的可行性。
143 whispered Chinese speech records spoken by 32 persons are analyzed in this paper. And the difference between one speaker＇s several spectrums of long-term average power spectral density is ｜ess than the difference between different speakers＇ ones. Then a method based on comparison of two whispered Chinese speech records＇ spectrums for voiceprint recognition is produced, and verification experiment shows it feasibility.
