使用x-向量的说话人条件声学到发音反转

Speaker conditioned acoustic-to-articulatory inversion using x-vectors

Aravind Illa, Prasanta Kumar Ghosh

摘要:

言语的产生涉及到各种发音器官的运动,包括舌头、下巴和嘴唇。从语音声学来估计发音器官的运动被称为声学发音反转(AAI)。最近,已经表明,与以特定于说话者的方式训练AAI不同,汇集来自多个说话者的声学发音数据是有益的。此外,通过在AAI的输入处的独热编码与声学特征一起使用扬声器特定信息的附加调节有益于在封闭设置的扬声器训练和测试条件下的AAI性能。在这项工作中,我们进行了实验研究的好处,使用x向量提供扬声器的特定信息条件AAI。30个说话人的实验表明,AAI性能受益于在闭集看到说话人条件下使用x向量。此外,x向量也很好地推广了未见过的扬声器评估。

英文摘要:

Speech production involves the movement of various articulators, including tongue, jaw, and lips. Estimating the movement of the articulators from the acoustics of speech is known as acoustic-to-articulatory inversion (AAI). Recently, it has been shown that instead of training AAI in a speaker specific manner, pooling the acoustic-articulatory data from multiple speakers is beneficial. Further, additional conditioning with speaker specific information by one-hot encoding at the input of AAI along with acoustic features benefits the AAI performance in a closed-set speaker train and test condition. In this work, we carry out an experimental study on the benefit of using x-vectors for providing speaker specific information to condition AAI. Experiments with 30 speakers have shown that the AAI performance benefits from the use of x-vectors in a closed set seen speaker condition. Further, x-vectors also generalizes well for unseen speaker evaluation.
