摘要
谱减法作为一种很有效的语音信号处理手段,广泛应用于现代语音增强系统中。针对低功耗设计的要求,本系统采用功耗低且功能强大的ARM芯片,用C语言编程将算法成功移植到ARM系统中,该系统功耗低,并有效地减小了噪声,改善了语音通信质量。
Spectral subtraction, as a very effective means of speech signal processing, is widely used in modern speech enhancement system. For low-power design requirements, the system used low power consumption and multi-function ARM chip, with C language program algorithm successfully transplanted into ARM system, and this system has lower power consumption, more effective in reducing noise, better quality of speech communications and good practicability.
