这份报告概述了项目修改语音信号与各种不同的效果。实现的效果是一个呼应,相移和残余阈值剪裁。的分析过程和技术参与实施这些技术也提供了一个洞察整个项目选择背后的原因。这份报告将细分一个语音信号的分解步骤,将段到频域,估计谱包络,操纵信号以不同的方式,然后回到回放的时间域。附录中提供一份项目以及示例输出结果。还提到可能的扩展项目,可能会增强其功能和团队的建议进行这些增强功能。-This report outlines a project to modify a speech signal with various different effects. The effects implemented were an echo, a phase shift and a residual threshold clipping. An analysis of the process and techniques involved in implementing these techniques is also offered with an insight into the reasons behind the choices made throughout the project. This report will break down the steps of segmenting a speech signal, transferring segments into the frequency domain, estimating the spectral envelope, manipulating the signal in various ways, then returned to the time domain for playback. A copy of the project is provided in the appendix as well as sample output results. Also mentioned are possible expansions on the project that could enhance its functionality and the team’s recommendations in proceeding with these enhancements.
