One way to create such an acoustic black hole is to use a device that hydrodynamicists call a Laval nozzle.

创造这种声学黑洞的方法之一，是利用一种流体力学家称为「拉瓦尔喷嘴」的装置。

It is a gradient-based method, which determines that the final solution is just a local optimum for the objective function, the likelihood that the models produce the training data.

本论文以进化计算为核心优化算法，主要研究了它在语音识别中的声学模型训练以及说话人辨认中的模型训练中的应用。

Of interest to Electroacoustic Music Studies is the relationship between the working methods associated with equipment such as the magnetic tape recorder, voltage-controlled synthesizer, mixing desk, and the aesthetics of the music produced by such means.

对于电子声学音乐而言，其兴趣在于研究两件事物之间的关系：一个是使用诸如磁带录音机、电压控制的合成器、调音台这一类设备进行创作的工作习惯；另一个是这种工作习惯所带来的，来自音乐美学方面的对于作品的思考。

Mechanical vibrations and mechanical wave as important knowledge in physics, it is not only the key content ...

机械振动和机械波是"复合概念"，本身包含着众多子概念，又把力学和运动学的诸多概念和知识综合应用于其中，同时在力学、电磁波、声学，甚至原子和量子理论中又都有着广泛的应用。

MIDI Controller This feature will turn your acoustic piano into a MIDI Controller. With this system you can use your acoustic piano's keyboard to record music to a computer, send keyboard and pedal data to a digital piano, external sound module, sequencer or other MIDI device.

MIDI控制器这一功能可把你的声学钢琴成为一个MIDI控制器，有了这种系统，你可以用你的原声钢琴的键盘记录音乐，以一台电脑，送键盘和踏板数据，以数码钢琴，外部音源，音序器或其它MIDI设备。

The current automatic mispronunciation detection systems are mostly based on automatic speech recognition framework with statistical model.

统计语音识别框架是现在发音错误检测系统的主流框架，而声学模型则是统计语音识别的基础。

This paper presents the methods to improve the performance of mispronunciation detection at syllable level for Mandarin Chinese from two aspects: introducing the speaker adaptive training and the selective maximum likelihood linear regression to get a better acoustic statistical model, and proposing speaker normalization backend because of the limited information and the different rating level for the different pronunciation level.

该文一方面为了获得对于发音错误检测更好的声学模型，引入了说话人自适应训练和选择性最大似然线性回归技术；另一方面，由于字发音检错中存在严重的信息量不足问题和专家对于不同水平说话人的评价标注不一样，在后端上加入了话者得分归一化技术。
