Our paper Mining the Spoken Wikipedia for Speech Data and Beyond has been accepted at LREC. Timo presented it and the reception seemed to be rather good. You can find our paper about hours and hours of time-aligned speech data generated from the Spoken Wikipedia at the Spoken Wikipedia Corpora website. There is about 200 hours of aligned data for German alone!
Of course, all data is available under CC BY-SA-3.0. :-)
