ABSTRACT:
An article of manufacture having voice-recording and recorded voice-playback mechanisms having a cube external shape, which is disguised as a household decorative fixture, e.g. a photograph holder, and internally bounding an echo chamber, e.g. a volume of at least 60 cubic inches, such that there is sufficient clarity in the played back recording due to the use of the echo chamber to enable recognition of the voice, to thereby add to the gift value of the article of manufacture.
