How to capture and save an online mp3?

[joe at actionline.com]

I asked: (1) How can I capture and save an online mp3 to a file on
my local computer? (2) How can I get it transcribed to a text file?

Matt answered (part 1 in part):
wget http://example.org/file.mp3


Thanks Matt. 'wget' worked perfectly to capture the file.

I've searched the 'net' but cannot find a Linux tool
to get the audio transcribed to text.

Is there a way to feed an audio file through google voice?
