通过年龄修正对声音伪装效果的知觉评价

Perceptual Evaluation of the Effectiveness of Voice Disguise by Age Modification

摘要:

语音伪装,有目的地修改一个人的说话者身份,目的是避免被识别为自己,是一种低努力的方式来欺骗说话者识别,无论是由人类还是自动说话者验证(ASV)系统执行。我们提出了一个评估的有效性的年龄刻板印象作为一种声音伪装策略,作为我们最近的工作,60名芬兰母语的人试图听起来像一个老人,像一个孩子的后续行动。在这项研究中,我们提出的证据表明,ASV和人类观察者都很容易错过目标说话者,但我们没有解决所提出的声音年龄刻板印象的可信度;这项研究有助于填补这一空白。有趣的情况是说话者成功地被ASV系统错过,并且典型的听众无法检测到伪装。我们进行了感知测试,研究伪装语音样本的质量。听力测试在当地和亚马逊的土耳其机器人(MT)人群工作者的帮助下进行。共有91名听众参加了测试,并被要求估计说话者的年龄和预期年龄。结果表明,年龄估计为预期的老人和儿童的声音为女性发言人的目标年龄组,而男性发言人,年龄估计对应的方向的目标声音只有老人的声音。在预期的儿童的声音的情况下,听众估计男性发言者的年龄比他们的实际年龄大,大多数发言者,而不是预期的目标年龄。

英文摘要:

Voice disguise, purposeful modification of one's speaker identity with the aim of avoiding being identified as oneself, is a low-effort way to fool speaker recognition, whether performed by a human or an automatic speaker verification (ASV) system. We present an evaluation of the effectiveness of age stereotypes as a voice disguise strategy, as a follow up to our recent work where 60 native Finnish speakers attempted to sound like an elderly and like a child. In that study, we presented evidence that both ASV and human observers could easily miss the target speaker but we did not address how believable the presented vocal age stereotypes were; this study serves to fill that gap. The interesting cases would be speakers who succeed in being missed by the ASV system, and which a typical listener cannot detect as being a disguise. We carry out a perceptual test to study the quality of the disguised speech samples. The listening test was carried out both locally and with the help of Amazon's Mechanical Turk (MT) crowd-workers. A total of 91 listeners participated in the test and were instructed to estimate both the speaker's chronological and intended age. The results indicate that age estimations for the intended old and child voices for female speakers were towards the target age groups, while for male speakers, the age estimations corresponded to the direction of the target voice only for elderly voices. In the case of intended child's voice, listeners estimated the age of male speakers to be older than their chronological age for most of the speakers and not the intended target age.
