摘要

随着信息技术的飞速发展和智能终端的不断升级，二维码作为一种存储、传递和检索信息的载体得到了广泛的应用。由于容量有限，目前的二维条形码被设计为只嵌入文本信息。本文提出了一种声学二维条码的生成方法。它以语音压缩为基础，通过引入MELP压缩方法，在保持高语音质量的同时获得低编码率。然后嵌入压缩数据流以生成二维条形码。在实际应用中，安装了解码软件的智能终端可以很容易地对声学二维码进行扫描，然后对嵌入的语音进行解码和播放。当压缩率为600bps时，嵌入式语音长度可达39s。从而有效地促进二维条码的应用。

A generation method for acoustic two-dimensional barcode

With rapid development of information technology and upgrading of intelligent terminals, two-dimensional barcode has been widely used as a carrier to store, transfer and retrieve information. Due to the limited capacity, current two-dimensional barcodes are designed to embed text-only messages. In this paper, a generation method for acoustic two-dimensional barcode is proposed. It is based on speech compression, in which low encoding rate is obtained while maintaining high voice quality by introducing MELP compression method. The compressed data stream is then embedded to generate the two-dimensional barcode. In practical applications, the acoustic two-dimensional barcode can be easily scanned by the intelligent terminals installed with decoding software, and then the embedded speech can be decoded and played. When compression rate is equal to 600bps, the embedded speech length can up to 39s. Thus, the application of two-dimensional barcode can be effectively promoted.
