摘要

本文提出了一种空间化音频多方电话会议系统,为群组电话会议提供了一种全新的通信体验。该系统包括我们最近开发的3D音频技术:3D声源定位(SSL)和3D音频捕获和重放,使用低成本和紧凑设计的麦克风阵列。从本质上讲,SAMT系统提供了3D音频捕获能力和空间音频感知能力,在一个地点有多个参与者,这在远程会议解决方案中仍然存在不足。除了能够识别和自动跟踪主动说话者之外,该系统还允许更引人注目的视觉呈现,以实现有效的沟通。该系统只需要一个低成本的麦克风阵列和一个消费者深度相机,就可以在普通笔记本电脑或台式电脑上可靠、舒适地实时运行。有了这样一个最小的部署需求,我们提供了由SAMT创建的各种用户体验。

Spatialized audio multiparty teleconferencing with commodity miniature microphone array
This paper presents a Spatialized Audio Multiparty Teleconferencing (SAMT) system with a radically new communication experience for group teleconferencing. The system includes our recently developed 3D audio technologies: 3D sound source localization (SSL) and 3D audio capture and reproduction using a low-cost and compact design microphone array. In essence, the SAMT system offers 3D audio capture capability and spatial audio perception with multiple participants at a site, which still falls short in teleconferencing solutions. In addition to being able to identify and automatically track the active speaker, the system allows more compelling visual presentation for effective communication. Requiring only a low-cost microphone array and a consumer depth camera, the proposed system runs reliably and comfortably in real time on a commodity laptop or desktop PC. With such a minimal deployment requirement, we present a variety of user experiences created by SAMT.
