Problems solved by technology

Also, the final destination of the data may not always be within close range
For example, an individual may wish to send information over a telephone or mobile phone, which often involves speech compression and decompression, which may significantly distort said information

Embodiment Construction

[0024] The embodiments described below allow digital data to be sent and received using sound. Typically, the digital data is converted or mapped to at least one sound parameter for synthesizing the sound. The sound parameter(s) are then used to generate artificial sounds. Thus, the generated artificial voice encodes digital sound, and digital data is transmitted by uttering the sound. When recovering the data, the relevant sound parameter(s) are extracted from the received sound and converted back into digital data. To convert between data and the parameter(s), a set of relationships is defined such that a particular parameter(s) with a chosen property represents a predetermined pattern of bits.

[0025] As disclosed herein, the term "sound" refers to sound or pressure waves or vibrations passing through a gas, liquid or solid. Sounds include ultrasonic, audible and infrasound. The term "audible sound" refers to sound frequencies that lie within the sound spectrum, which ...

Abstract

Apparatus and method are disclosed for data communication using sound. Generally, an apparatus for transmitting digital data comprises a data coder configured to convert the digital data into one or more types of sound parameters, and a sound synthesizer coupled to the data coder and configured to generate sound based on the one or more types of sound parameter. An apparatus for receiving digital data comprises a sound analyzer configured to receive sound and to extract one or more types of sound parameters from the received sound, and a data decoder coupled to the sound analyzer and configured to convert the extracted one or more types of sound parameters into the digital data.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to co-pending US Provisional Patent Application No. 60 / 413,981, filed September 25, 2002, and entitled "Data Communication Through Acoustic Channels And Compression." The disclosure of the above provisional application is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to data communications, and more particularly to data communications via voice channels. technical background [0004] Advances in communication technology have made sharing and / or forwarding information easier and faster. Large volumes of data may be transferred via a data transmission system, such as a local or wide area network (eg, the Internet), a cellular network, and / or a satellite communication system. These systems require complex hardware and / or software and are generally designed for high data rates and / or long transmission ranges. [0005] F...
