Abstract

ABSTRACT This study presents a perceptual analysis of the Brazilian Portuguese wh-question and wh-exclamation intonational contours to discriminate their acoustic and perceptual features. The corpus of this study is composed of the sentence “Como você sabe” (“How do you know” vs. “How clever you are!”), which was produced with both speech acts. Two perceptual identification experiments were designed to assess the subjects’ ability to identify these speech acts based on their prosodic characteristics, as well as the perceptual relevance of specific prosodic cues in the recognition of wh-questions and wh-exclamations. The results of the first perceptual test indicated that Brazilian listeners can identify these two speech acts by intonation only, whereas the second test showed that F0, duration and intensity cues contribute to the perceptual identification of the speech acts. Stimuli with a falling F0 movement in the last stressed syllable tend to be interpreted as wh-questions, whereas stimuli with a slightly rising F0 movement tend to be judged as wh-exclamations.

F0运动、强度和持续时间对巴西葡萄牙语wh-疑问句和wh-惊叹词知觉识别的影响

摘要:本研究对巴西葡萄牙语的wh-疑问句和wh-感叹词的语调轮廓进行感性分析，以区分它们的声学特征和感性特征。本研究的语料库由句子“Como você sabe”(“How do you know”vs.“How clever you are!”)组成，该句子由两种言语行为共同产生。设计了两个感知识别实验，以评估受试者基于韵律特征识别这些言语行为的能力，以及特定韵律线索在识别wh-question和wh-感叹中的感知相关性。第一个感知测试的结果表明，巴西听众只能通过语调识别这两种言语行为，而第二个测试的结果表明，F0、持续时间和强度线索有助于言语行为的感知识别。最后一个重读音节F0下降的刺激倾向于被解释为“wh-疑问句”，而F0稍微上升的刺激倾向于被判断为“wh-惊叹词”。
