hi everyone,
using kiku you can patch with your voice (english or japanese). it's available only for ubuntu / debian (32bit / 64bit) and it works with pulseaudio.
you can see it in action in this video:
you can download it here:

btw, i am using libpd to filter the voice (i/o on both audio and message).
cheers!
