echo control meaning in English
回波控制
Examples
- Acoustic processing and echo control sound pickup and playback is an important area of multimedia processing
声学处理和回声控制拾音和重放是多媒体处理的一个重要领域。 - The primary advances in speech and audio signal processing that contributed to multimedia applications are in the areas of speech and audio signal compression , speech synthesis , acoustic processing , echo control and network echo cancellation
语音和音频信号处理的改进对多媒体应用的贡献在下述范围：语音和音频信号压缩、语音合成、声学处理、回声控制以及网络回声消除。 - Signal processing for acoustic echo control includes modeling of reverberation , design of dereverberation algorithms , echo suppression , double - talk detection and adaptive acoustic echo cancellation , which is still a challenging problem in stereo full - duplex communication environments [ 3 . 53 ]
声学回声控制的信号处理包括回响模型、消回响算法设计、回声抑制、双方讲话检测以及适应回声消除，这仍然是立体声全双工通信环境中富有挑战性的问题。 - The idea of acoustic signal processing and echo control is to allow straightforward high - quality sound pickup and playback in applications , such as a duplex device like a speakerphone , a sound source - tracking apparatus like microphone arrays , teleconferencing systems with stereo input and output , hands - free cellular phones and home theatre with 3d sound
声学信号处理和回声控制是想在应用中能够获得高质量的拾音和重放，这些应用包括耳麦之类的双工设备、麦克风阵列之类的声源跟踪设备、立体声输入输出的远程会议系统、不用手的蜂窝电话以及3d声音的家庭影院等。 - Hands - free speech communication is indispensable in audio and video conference systems , hot - line telephones and videophones , mobile radio terminals , digital isdn network etc . however , the control ( cancellation ) of the acoustic echo has always had a strong impact on the transmission quality in hands - free telecommunication ~ [ 1 - 3 ] conventional methods of acoustic echo control ( cancellation ) , such as echo suppression or gain control , may lead to the degradations in speech quality or make the speakers feel uncomfortable
免提式话音通信在移动电话、热线电话、车载电话及isdn网的电视电话会议等多种领域正得到日益广泛的应用。但至今的免提式话音通信中，仍免不了受回声引起的话音失真、甚至啸叫等干扰，大大降低了免提话音通信的质量。由于声回波对消问题尚未得到圆满解决，实现高质量的免提式话音通信仍是一个极赋挑战性的课题。
