echo suppression meaning in Chinese

回波信号的抑制
回波信号抑制
回波抑制

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。
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。
