A Contrastive Study Of Dialects Of Prosotometric Vertex

Over the past twenty years, the study of language rhythm structure is phonetics and linguistics and psychology of the interdisciplinary subject, is a frontier subject in the experimental phonetics research. This article from the presence of seriousness to distinguish with respect to the manner of focus to realize the impact angle of four Chinese dialect research focus stress rhythm encoding.First studied mandarin (Nanjing dialect and Xuzhou dialect) and wu (Suzhou dialect and Changzhou dialect) single syllables focus stress rhythm encoding. Using the q&a matching paradigm, asked participants to natural dialogue in pairs of two different focus way (narrow focus and wide focus) sentences. Through the analysis of the acoustic system and statistical measurement, the results show that:Wu district, in Changzhou dialect, the rhythm of focal stress encoding to focus syllable pitch itself significantly reduced, the length is prolonged, pitch plunged after focus (post-focus FO compression will PFC), the length is prolonged; In Suzhou dialect, focus on the rhythm of stress encoding performance for focus syllables itself a significant rise in pitch, length, focus syllable pitch decreased significantly after (PFC). Mandarin area:in Nanjing dialect, no significant change in focus syllable pitch, pitch range expanded significantly, the length is prolonged, focus syllable pitch decreased significantly after (PFC), the duration is prolonged; In Xuzhou dialect, no significant change in focus syllable pitch and pitch range, duration is prolonged, the focus of syllable pitch decreased significantly after (PFC), extended length significantly.One-syllable focus in four dialects are the focus of pitch after dropping (PFC) phenomenon, in order to verify the rhythm of monosyllabic focus stress encoding, this paper also studies the four kinds of dialect in the rhythm of double syllable stress focus encoding, divided into wide focus, focus and sentences focus in three conditions, by using the method and statistical analysis of monosyllabic similar results:Under the condition of the sentence first focus, focus of Changzhou dialect syllable pitch range expanded significantly, length, focus syllable pitch decreased significantly after (PFC). Suzhou dialect focus syllable pitch range expanded significantly, extended length, focus syllable pitch decreased significantly after (PFC). Nanjing dialect focus syllable pitch range expanded significantly, extended length, focus syllable pitch decreased significantly after (PFC). Xuzhou dialect focus syllable pitch range expanded significantly, extended length, focus syllable pitch decreased significantly after (PFC). Under the condition of the sentence focus, the rhythm of four dialects point encoding and sentence first focus, plunging phenomena have appeared after the focus pitches.Finally concluded that the presence of light and heavy sound to distinguish between dialects of focal stress rhythm, there is no significant difference among the encoding, four dialects points under the condition of different focus has a significant focus of pitch plunged after (PFC) phenomenon. In addition, and Beijing dialect belong to the same sino-tibetan wu dialects and mandarin are pitch plunged after the "focus", therefore, the conclusion of this article in accordance with Xu and the source of the same pitch plunged after the "focus".
