Concept: Love Wave

The idea here is taking ones voice speaking "I love you" and converting it into a tangible thing. The tangible thing in this case works as a bespoke necklace pendent. Everyone speaks differently and therefor every Love Wave pendent would be custom made for its owner's voice via on-demand manufacturing ala 3D printing. Thoughts? This needs a web app developed for it so customers can say the words and instantly see the 3D representation of it... any volunteers?
