摘要翻译：
在竞技体育中，往往很难量化成绩。一个球员得分或超车可能只取决于毫秒或毫米。在网球、乒乓球、壁球等球拍运动项目中，许多项目都是在短时间内发生的，对其进行记录和分析有助于揭示比赛成绩的差异。在这篇文章中，我们证明了有可能构建一个框架，利用特征声音模式来精确地分类这些事件的类型和定位这些事件的位置。根据这些基本信息，可以估计出沿轨迹的击球类型和球速。将这些估计值与最佳速度和目标进行比较，可以确定射击的精度。详细的镜头统计和精度信息极大地丰富和改进了今天可用的数据。反馈给运动员和教练员有助于客观地描述比赛表现，提高战术技能。实现了该框架，并在一个壁球场安装和测试了该框架的硬件和软件组件。

英文摘要：
In competitive sports it is often very hard to quantify the performance. A player to score or overtake may depend on only millesimal of seconds or millimeters. In racquet sports like tennis, table tennis and squash many events will occur in a short time duration, whose recording and analysis can help reveal the differences in performance. In this paper we show that it is possible to architect a framework that utilizes the characteristic sound patterns to precisely classify the types of and localize the positions of these events. From these basic information the shot types and the ball speed along the trajectories can be estimated. Comparing these estimates with the optimal speed and target the precision of the shot can be defined. The detailed shot statistics and precision information significantly enriches and improves data available today. Feeding them back to the players and the coaches facilitates to describe playing performance objectively and to improve strategy skills. The framework is implemented, its hardware and software components are installed and tested in a squash court.
