摘要
为了使云制造的各种资源和服务通过云终端为人们使用,研究了自然人机交互模式,使人们以多种通道自然、高效地通过云终端使用云制造的资源和服务,其中语音交互是人类最自然的交互通道。在实际应用中必须对自然语音信号进行预处理,以从含噪语音中得到干净的语音信号。提出一种基于听觉掩蔽效应的改进型谱减法语音增强技术,引入了新的语音端点检测算法,克服了音乐噪声的影响,提取到纯净语音。通过对其进行仿真,验证了算法的有效性。
To use the resources and services of cloud manufacturing through cloud terminal,the natural man-machine interaction mode was researched.Thus the resources of cloud manufacturing could be used efficiently by multiple channels.Speech interaction is the most natural interactive channel for human,and the natural language signal must be preprocessed in practical application to obtain clear speech signal from noisy speech.An improved spectral subtraction speech enhancement algorithm based on auditory masking effect was proposed.A new speech endpoint detection method was introduced to overcome the music noise influence and to extract the pure speech.The simulation results verified the effectiveness of the proposed algorithm.
