VoiceQR will probably have a limited interest (especially in Japan with pervasive 3G), as it is much easier to directly link to a larger sound file available on the internet trough an URL.

However it shows well where we are headed. Mobile phone cameras become ever more sophisticated and if sound files can directly be integrated in the code, this also shows how small QR Codes have become in Japan.

We are still some years behind the japanese phone sophistication (some progress have been made with the N95 and the iPhone), but it's good to know that the future is already here.
It also shows that short code (small amount of numbers) approaches* will obviously soon be a thing of the past.

* All proprietory codes use short codes (numbers or a mix of numbers and letters), whereas with the standards (QR Codes, Datamatrix) you can choose. Right now we use short codes only when space is an issue and we recommend to use URL's respectively Short Code URL's.
