Contribution
It presents a novel approach to send voice messages over SMS by encoding and compressing PCM audio into text format.
Findings
Successful transmission of PCM audio over SMS
Effective compression reduces message size
Prototype application demonstrates feasibility
Abstract
The paper presents the method of transferring PCM (Pulse-Code Modulation) based audio messages through SMS (Short Message Service) over GSM (Global System for Mobile Communications) network. As SMS is text based service, and could not send voice. Our method enables voice transferring through SMS, by converting PCM audio into characters. Than Huffman coding compression technique is applied in order to reduce numbers of characters which will latterly set as payload text of SMS. Testing the said method we develop an application using J2me platform
