Various stimulus types have been investigated in pitch discrimination and pitch matching tasks. However, previous studies have not explored the use of recorded samples of an individual's own voice in performing these two tasks. The purpose of this study was to investigate pitch discrimination and pitch matching abilities using three stimuli conditions (participant's own voice, a neutral female voice, and nonvocal complex tones) to determine if pitch discrimination and/or pitch matching abilities are influenced by the type of stimuli presented. Results of the pitch discrimination tasks yielded no significant difference in discrimination ability for the three stimuli. For the pitch matching tasks, a significant difference was found for the participants' voice versus neutral female voice and the participants' voice versus tonal stimuli. There was no significant difference in pitch matching ability between the neutral female voice and the tonal stimuli. There was no significant correlation between pitch discrimination and pitch matching abilities for any of the three stimuli types. These results suggest that it is easier to match the pitch of one's own voice than to match the pitch of a neutral female voice and nonvocal complex tones, although no difference was found for pitch discrimination abilities. One possible implication of this study is that differences in matching the pitch of one's own voice compared to matching other stimuli types may help to differentiate the source of singing inaccuracy (motor vs discrimination skills).
在音高辨别和音高匹配任务中,已经对各种刺激类型进行了研究。然而,以往的研究尚未探讨在执行这两项任务时使用个人自己声音的录音样本。本研究的目的是使用三种刺激条件(参与者自己的声音、中性女性声音和非语音复合音调)来研究音高辨别和音高匹配能力,以确定音高辨别和/或音高匹配能力是否受所呈现刺激类型的影响。音高辨别任务的结果显示,三种刺激的辨别能力没有显著差异。对于音高匹配任务,发现参与者自己的声音与中性女性声音以及参与者自己的声音与音调刺激之间存在显著差异。中性女性声音和音调刺激之间的音高匹配能力没有显著差异。三种刺激类型中的任何一种,其音高辨别和音高匹配能力之间均无显著相关性。这些结果表明,尽管在音高辨别能力上没有发现差异,但匹配自己声音的音高比匹配中性女性声音和非语音复合音调的音高更容易。这项研究的一个可能意义是,与匹配其他刺激类型相比,匹配自己声音音高的差异可能有助于区分歌唱不准确的来源(运动技能与辨别技能)。
