For that, just record a new wave file with your speech using the following command: $ arecord -f S16_LE -c 2 -r 48000 audio.wav. This would record from your system’s default mic. Interestingly, audio loopback could also be achieved in user space using alsaloop from alsa-utils package. Here is a demo of the same.

In order to record from a device, the device's "capture" switch must be set. To do so, run alsamixer, select your microphone and press space. Something like... CAPTUR L R. should appear. On some cards there is a separate "Capture" device, which must be set to capture as well (and be unmuted, and have volume increased).
