| 摘 要： | 用LabVIEW软件实现了在语音信号中嵌入文本信息水印．系统由水印嵌入和水印提取2部分组成．语音信号由麦克风输入，水印信息由LabVIEW支持的文本框输入，嵌入水印信息的音频信号以．WaV文件形式保存，通过水印提取系统可将嵌入音频信号内的保密文本信息还原．利用LabVIEW实现了既有嵌入程序又有提取程序的完整音频水印系统．

| Abstract: | The proposed system uses LabVIEW software to realize the function of embedding text information into audio signal. The system consists of two parts, a watermark embedding and a watermark retrieving. The audio signal is sampled from a microphone. The watermark information is obtained from the text box in the LabVIEW pro- gram. The audio signal with watermark is stored in. wav format. The text message embedded in the audio signal can be retrieved through the watermark extracting system. The integral audio watermark system is achieved with both embedding and retrieving program using LabVIEW. |
