作者你好,我看数据集人声目标存在200hz高通滤波,请问该数据集有没有没有进行高通滤波的原始版本

你好,数据集开源的数据未进行高通滤波。用于生成目标语音(增强标注)的设备频响是单独测量的,测量使用的扫频信号频率范围是0-24kHz,因此设备频响的频率范围也是0-24kHz,未涉及200hz高通滤波。
Sorry, something went wrong.
感谢回复,训练出来的模型对0-200hz的人声保留程度不是很好,我抽取部分数据(训练、验证)看0-200hz的人声数据都是存在缺失的,以为数据集进行了预处理。
一般,说话人基频(女性普遍高于男性)以下的频率声学成分较弱,可能抽取数据的说话人基频在0-200Hz之内,所以小于基频会存在人声‘’缺失‘’,可以关注一下听感上是否出现异常。
