Is Coarticulation in Speech Kinematics Centrally Planned ?

چکیده

Coarticulation in speech production is a phenomenon in which the articulator movements for a given speech sound vary systematically with the surrounding sounds and their associated movements. Although these variations may appear to be centrally planned, without explicit models of the speech articulators, the kinematic patterns which are attributable to central control cannot be distinguished from those which arise due to dynamics and are not represented in the underlying control signals. In the present paper, we address the origins of coarticulation by comparing the results of empirical and modeling studies of jaw motion in speech.

Coarticulation of jaw movements in speech production: is context sensitivity in speech kinematics centrally planned?

Coarticulation in speech production is a phenomenon in which the articulator movements for a given speech sound vary systematically with the surrounding sounds and their associated movements. Although these variations may seem to be planned centrally, without explicit models of the speech articulators, the kinematic patterns that are attributable to central control cannot be distinguished from ...

Individual variability in the perception and production of coarticulated speech

Coarticulation, the influence of speech sounds on each other, is ubiquitous in speech. Such contextual effects in speech have been argued to be phonological in nature, given that coarticulation appears to be language-specific and planned. In this talk, I argue further for the phonological nature of coarticulation, using findings from recent behavioral and neurophysiological studies. In particul...

Coarticulation Is Largely Planned *

Is coarticulation a reflection of planning an utterance or the automatic effect of producing speech? This question was examined by requiring speakers to begin reading nonsense aCV or abVCa strings (where C was fbi or IpI and V was Iii or lui) aloud before seeing the entire utterance. Those segments known before articulation began exerted normal anticipatory coarticulatory influences, while thos...

Allophone-based acoustic modeling for Persian phoneme recognition

Phoneme recognition is one of the fundamental phases of automatic speech recognition. Coarticulation which refers to the integration of sounds, is one of the important obstacles in phoneme recognition. In other words, each phone is influenced and changed by the characteristics of its neighbor phones, and coarticulation is responsible for most of these changes. The idea of modeling the effects o...

Implement of Coarticulation in Physiological Articulatory Model

One of the fundamental issues to achieve a speech synthesizer using a physiological articulatory model is the implementation of coarticulation. This study focuses on the coarticulation occurred in the target planning stage, and proposes a “carrier model” to realize the coarticulation mechanism. Simulation results show that the carrier model demonstrates a good performance to account for the coa...
