Turn taking-based conversation detection by using DOA estimation
نویسندگان
چکیده
We propose a new method that detects conversation groups when multi-conversation groups exist simultaneously. The proposed method uses hands-free microphone arrays without wearable microphones. It has two main features: (a) We integrate a conventional turn taking-based conversation detection method with Direction of Arrival (DOA) estimation-based Voice Activity Detection (VAD). (b) The proposed method estimates the number of speakers for DOA estimation-based VAD by using the turn-taking rules. Experimental results indicate that the performance of the proposed method with only microphone arrays setup in rooms is comparable to that of the conventional methods with wearable microphones.

Turn-Taking Estimation Model Based on Joint Embedding of Lexical and Prosodic Contents
A natural conversation involves rapid exchanges of turns while talking. Taking turns at appropriate timing or intervals is a requisite feature for a dialog system as a conversation partner. This paper proposes a model that estimates the timing of turn-taking during verbal interactions. Unlike previous studies, our proposed model does not rely on a silence region between sentences since a dialog...
متن کاملImplementation of the direction of arrival estimation algorithms by means of GPU-parallel processing in the Kuda environment (Research Article)
Direction-of-arrival (DOA) estimation of audio signals is critical in different areas, including electronic war, sonar, etc. The beamforming methods like Minimum Variance Distortionless Response (MVDR), Delay-and-Sum (DAS), and subspace-based Multiple Signal Classification (MUSIC) are the most known DOA estimation techniques. The mentioned methods have high computational complexity. Hence using...
متن کاملTurn-Taking, Preference, and Face in Criticism Responses
Vivas have multiple functions in academia, but their main goal is completing thesis evaluation. At the heart of this evaluation is a series of criticisms and their responsive turns by which participants talk vivas as institution into being (Heritage, 1997). Turn-taking is one of the many ways vivas are talked into being. This study drew upon conversation analysis to look into the turn allocatio...
متن کاملDecoupled direction finding: detection
Antenna arrays are likely to be an important feature of future mobile communication systems. With an antenna array, mobile users can be separated by a spatial filtering procedure allowing several users on the same carrier frequency. The uplink part (mobile to base) not only can, but is better solved without using any spatial knowledge in terms of direction of arrival (DOA). However, DOA estimat...
متن کاملUnderdetermined Wideband DOA Estimation for Off-Grid Sources with Coprime Array Using Sparse Bayesian Learning
Sparse Bayesian learning (SBL) is applied to the coprime array for underdetermined wideband direction of arrival (DOA) estimation. Using the augmented covariance matrix, the coprime array can achieve a higher number of degrees of freedom (DOFs) to resolve more sources than the number of physical sensors. The sparse-based DOA estimation can deteriorate the detection and estimation performance be...
