PROBLEM TO BE SOLVED: To resolve a conventional problem of mixed noises in a digital voice signal processing built-in type eyeglass device, by comparing a display symbol with stored symbols to recognize it, and by stereoscopically displaying the recognized symbol on a transparent medium such as liquid crystal. SOLUTION: An analog-to-digital converter 101 digitizes an input analog voice signal. A voice recognition processing part 102 compares and collates the digitized voice signal with standard symbols previously stored in a standard memory 103 to decide a recognition voice, and converts the recognition voice into a display symbol having a given lump. The display symbol is sent to a display driver 104 so that the display symbol in one-to-one correspondence to the input analog voice signal is displayed on a stereoscopic display device 105. That is, the digital signal processing processes and stores a frequency characteristic of the input voice signal, converts the signal into the display symbol having the given lump, compares the display signal with the stored symbols to recognize it, and stereoscopically displays it on a transparent medium such as liquid crystal.
