Sample speech wave files

I often find myself looking for sample speech utterances when I need to do something quick, for example, checking a program or making a plot. The closest resources online are probably audio files of speeches on Wikimedia or on Freesound, but it's hard to find short recordings. (Maybe I'm just lazy.)

So here you go. Below are four wave files from LibriSpeech (after Kaldi's processing). I hope they will help people who have the same problem.
