2023年9月1日 · Voice Activity Detection (VAD) is a crucial component of Speech Enhancement (SE) for accurately estimating noise, which directly affects the SE effectiveness in improving speech quality. However, conventional non-data-driven VADs often suffer from decreased accuracy at a low signal-to-noise ratio (SNR).

2021年8月27日 · After detecting the wakeword, use a longer VAD (phase 1 threshold) before deciding that there is no audio. After phase 1 "long" VAD, switch to "short" VAD (phase 2 threshold) to figure out when the user is done talking. Both options should be …

声音活动检测 （Voice activity detection： VAD），也称为 语音活动检测 或语音检测（speech activity detection或者speech detection），是检测人类语音存在与否的技术，主要用于 语音处理。 VAD的主要用途在于 说话人分割 （speaker diarization）、 语音编码 （speech coding）和语音识别（speech recognition）。 它可以促进语音处理，还可以用于在音频会话的非语音部分停用某些过程：它可以在 Voice over Internet Protocol (VoIP) 应用中避免对静音包的不必要编码/传 …

2022年9月13日 · The traditional dual-threshold-based VAD algorithm has very low detection accuracy in a low signal-to-noise ratio environment. This paper proposes a voice activity detection algorithm based on Ensemble Empirical Mode Decomposition (EEMD) combined with the dual-threshold method, which integrates the decomposition of EEMD.

We have developed a miniaturized 5-degrees of freedom (5-DOF) control axial gap type double stator maglev permanent magnet motor for use in paediatric VAD. The developed double permanent motor can be miniaturized and have large air-gap because the permanent magnet produce the high magnetic flux density in the air-gap.

This patient was on a double Berlin Pump ventricular assist device (VAD) for one year prior to receiving their transplant. This model shows the exit from the Left ventricle where one pump pulled in blood, and both tubes (Partially captured by the 3D scan) returning blood to the aorta and pulmonary artery.

2024年7月18日 · 本章节旨在对VAD（Vectorized Scene Representation for Efficient Autonomous Driving）方法进行全面的解读和总结。VAD方法针对自动驾驶领域中的轨迹规划问题，提出了一种创新的矢量化场景表示范式，有效克服了现有方法在计算效率、安全性和规划流程上的局限性。

6.1.4.2 Vapour-Phase Axial deposition (VAD) VAD is a very important process and accounts for a large proportion of world fibre production. It was originally intended to be a continuous process which would have a lot lower cost than the batch processes.
