Output to stderr doesn't necessarily mean a command failed. The
process returncode is what you need to inspect. Use
subprocess.check_output. It raises a subprocess.CalledProcessError for
a non-zero return code.

Please post plain text to the list. Automatic conversion from rich to
plain text isn't Python friendly.
Don't use eval like this. Google isn't sending Python code in response
to a web query. They're sending JSON data:
import json
output = ('{"status":0,"id":"","hypotheses":'
'[{"utterance":"Python","confidence":0.58060002}]}')
a = json.loads(output)
>>> a['hypotheses'][0]
{u'confidence': 0.58060002, u'utterance': u'Python'}
>>> a['hypotheses'][0]['utterance']
u'Python'
Remember to check the status code. I found a short list, but nothing official:
0 - correct
4 - missing audio file
5 - incorrect audio file
When the speech recognition fails to form a hypothesis, print "Ozzy,
is that you again?" ;)
