Simulating Post-L F0 Bouncing by Modeling Articulatory Dynamics
نویسندگان
چکیده
Post-L F0 bouncing (post-L bouncing for short) is a prosodic phenomenon whereby F0 is temporarily raised following a very low pitch. The phenomenon is quite robust, but is not widely known, and it has never been computationally modeled. This paper presents the results of our simulation of the phenomenon by modeling articulatory dynamics. Using the quantitative Target Approximation (qTA) model, we were able to simulate the F0 rise after the Mandarin L tone by adding an acceleration adjustment to the initial state of the first post-L Neutral tone. Furthermore, a linear relationship was found between the added acceleration and the amount of F0 lowering in the L tone. We interpreted the results as evidence that post-L bouncing is directly related to the articulatory mechanism of producing a very low pitch.

Interaction Between Lexical Tone and Intonation: An EMA Study
This paper aims to examine the interaction of intonation and lexical tone within the framework of Articulatory Phonology, by investigating the timing relationship between oral articulatory gestures and tone-related/intonation-related F0 dynamics. Specifically, we compared the consonant-vowel-F0 (C-V-T) coordinative patterns at phrase-final position and at phrase-medial position. We found that t...

This paper is an attempt to test PENTA, an articulatory-functional model, on Persian focus prosody. The test was done on a corpus consisting of utterances with different focus conditions using PENTAtrainer2, a trainable prosody synthesizer that optimizes categorical pitch targets each corresponding to multiple communicative functions. The evaluation was done by comparing the F0 contours generat...
متن کاملExploring Multidimensionality: Acoustic and Articulatory Correlates of Swedish Word Accents
This study investigates acoustic and articulatory correlates of South Swedish word accents (Accent 1 vs. 2) – a tonal distinction traditionally associated with F0 timing. The study is motivated by previous findings on (i) the acoustic complexity of tonal prosody and (ii) tonal-articulatory interplay in other languages. Acoustic and articulatory (EMA) data from two controlled experiments are rep...
متن کاملPost-low bouncing in Mandarin Chinese: acoustic analysis and computational modeling.
Post-low bouncing is a phenomenon whereby after reaching a very low pitch in a low lexical tone, F(0) bounces up and then gradually drops back in the following syllables. This paper reports the results of an acoustic analysis of the phenomenon in two Mandarin Chinese corpora and presents a simple mechanical model that can effectively simulate this bouncing effect. The acoustic analysis shows th...

The present article aims at exploring the invariant parameters involved in the perceptual normalization of French vowels. A set of 490 stimuli, including the ten French vowels /i y u e ø o E oe (inverted c) a/ produced by an articulatory model, simulating seven growth stages and seven fundamental frequency values, has been submitted as a perceptual identification test to 43 subjects. The result...
