阶层式口语韵律架构的深层语言学意义─来自不同的韵律格式及边界效应的新证据 鄭秋豫 中央研究院语言学研究所语音实验室 .tw/ Part 1. Prosodic Variations—Predictable? Fluent Speech Prosody (Paragraph Flow) Is Characterized by Higher Level Associations Instead of Strings of Unrelated Phrase Intonations. Mandarin fluent speech prosody can NOT be accounted for by tones and intonation only. Fluent speech prosody must taken into account higher level discourse information. One Such Base Form Is Sufficient to Derive Different Prosodic Styles; Paragraph Flow Can Be Represented by A Multi-phrase Base Form (Deep Structure). Output Prosodic Variations Are Style- and Prosodic-layer Dependent/Constrained; Quantitative Analysis of F0 Trajectories Provides Crucial Evidences. Background Hierarchical Prosodic Phrase Grouping (HPG) Framework (Tseng, 2004) 1. Provides the base form (deep structure) of fluent speech prosody (paragraph flow), and 2. Is able to account for various prosody formats. Ripples, Waves and Beyond Why from Ripples Upward to Waves and Speech Paragraphs 赵元任1968, intonation and tone 大波浪小波浪 The super-positional nature of tones, intonation, paragraph and discourse. both higher and lower prosody information syllable tone PG-Initial PG-Medial PG-Final ba 1 ba 2 ba 3 ba 4 Two Experiments Experiment 1: carrier paragraph with a simple and coherent PG. Examine cross-phrase F0 patterns to prove and predict higher-level discourse information using Fujisaki model in speech. Experiment 2: Mandarin rhymed speech with rhyme templates and various literature styles. Investigate the relationship between speaking styles and distribution of contribution from each prosodic layer Goals 1. To prove the existence of higher level information across different types of prosody styles. 2. To account for hierarchical contributions from HPG layers through quantitative analysis of speech corpora. Methodology 1. Selecting A Models to Analyze F0 Contour Trajectories That Reflects Super-positioning
