隨著物聯網（IOT）的快速發展，物件、設備和機器之間的通信成為一個熱門話題。條碼的應用已經成為該領域的不可取代的技術，它們提供了嵌入的各種信息，例如：超級鏈接和文本的方法。在本文中，我們提出了一個新穎的基於語音的二維條碼系統，該系統直接嵌入語音在條碼中。最初，語音數據流被編碼成二進制格式轉換成一個二維條碼符號。然後，可以由照像機獲取二維條碼，並通過一個解碼程序進行解碼。我們的系統被實現在有相機的標準移動設備上，它不需要任何的網絡連接。該方法適合用在多種用途，例如視障者的無障礙功能。

As the rapid development of the Internet of Things (IoT), communication between objects, devices and machines becomes a popular topic. The application of barcode has become an irreplaceable technique in the field of IoT, which provides a new way to embed various information such as hyperlink and text. In this thesis, we present a novel voice-based QRCode system, which directly embeds voice into a barcode. Initially, the voice data stream is encoded in a binary format into a QRCode symbol. Then, the camera acquires the QRCode symbol and decodes it with a decoding program. Our system is implemented on standard mobile devices with a camera. It does not need any network connection. The proposed method is suitable for plenty of uses, such as the accessibility feature for the visually impaired individuals.
