Kinematic Signatures of Prosody in Lombard Speech

چکیده
Human spoken interactions are embodied and situated. Better understanding of the restrictions and affordances this embodiment and situational awareness has on human speech informs the quest for more natural models of human-machine spoken interactions. Here we examine the articulatory realization of communicative meanings expressed through f0 falling and rising prosodic boundaries in quiet and noisy conditions. Our data show that 1) the effect of environmental noise is more robustly present in the post-boundary than the pre-boundary movements, 2) f0 falls and rises are only weakly differentiated in supra-laryngeal articulation and differ minimally in their response to noise, 3) individual speakers find different solutions for achieving the communicative goals, and 4) lip movements are affected by noise and boundary type more than the tongue movements.

An Acoustic Study of Emotivity-Prosody Interface in Persian Speech Using the Tilt Model
This paper aims to explore some acoustic properties (i.e. duration and pitch amplitude of speech) associated with three different emotions: anger, sadness and joy against neutrality as a reference point, all being intentionally expressed by six Persian speakers. The primary purpose of this study is to find out if there is any correspondence between the given emotions and prosody patterning in P...
متن کاملStudy on Unit-Selection and Statistical Parametric Speech Synthesis Techniques
One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...
متن کاملUnit selection based speech synthesis for poor channel condition
Synthesized speech can be largely degraded in noise, resulting in compromised speech quality. In this paper, we propose a unit selection based speech synthesis system for better speech quality under poor channel conditions. First, the measurement of speech intelligibility is incorporated in the cost function as a searching criterion for unit selection. Next, the prosody of the selected units is...
متن کاملArticulatory evidence for functional coupling of speech and non-speech motor tasks
Control of speech production is part of the larger motor control system, and as such can be organized into coordinative structures (or functional synergies) with other motor behaviors, that can then be parameterized as single functional units. The current study explores this phenomenon, expanding previous findings with direct kinematic evidence of speech production. Findings indicate that ampli...
متن کاملThe Prosody of Discourse Structure and Content in the Production of Persian EFL Learners
The present research addressed the prosodic realization of global and local text structure and content in the spoken discourse data produced by Persian EFL learners. Two newspaper articles were analyzed using Rhetorical Structure Theory. Based on these analyses, the global structure in terms of hierarchical level, the local structure in terms of the relative importance of text segments and the ...
