Sound generating device capable of reading codes

摘要

A sound generating device capable of reading codes is disclosed for reading machine readable code arranged on printing material to generate corresponding voice output. An image sensor captures an image of the machine readable code. An image processor preprocesses the image of the machine readable code for acquiring identifiable image signals. A decoder decodes the image signals, based on encoding rules of the machine readable code, into texts or symboles represented by the machine readable code. A voice generating table pre-stored with voice waveforms corresponding to various texts and symbols converts the decoded texts or symbols into voice waveforms. A digital to analog convertor converts the voice waveforms into corresponding analog speech or special sound effect to a speaker for broadcasting.
