US Patent 7899442 Multimedia data transfer for a personal communication device

In a portable multimedia device, data is passed between a sender and receiver unit by way of voice channel only. Multimedia data is vocalized and then forwarded to a receiver unit by way of the voice channel without the use of a backend server. Once received at the receiver unit, the vocalized data can be converted to an audio signal that can then output by way of an audio output device (such as a speaker, earphone, etc.).
