| Abstract: | Based on computer sound card and microphone hardware platform, a sound acquisi- tion system is built under LabVIEW environment. With this sound system, the voice signal under different conditions can be collected and processed, with the functions of preservation and playback, which is a powerful tool for sound vibration research and recognition under different conditions. |
