回答1:

The SpeechRecognition library requires Python 3.3 or up:

Requirements

[...]

The first software requirement is Python 3.3 or better. This is required to use the library.

and from the Trove classifiers:

Programming Language :: Python
Programming Language :: Python :: 3
Programming Language :: Python :: 3.3
Programming Language :: Python :: 3.4

The urllib.request module is part of the Python 3 standard library; in Python 2 you'd use urllib2 here.

回答2:

You can do that using Python 2.

1. Remove request
2. Make that line: from urllib2 import urlopen

You cannot have request in Python 2, you need to have Python 3 or above.

回答3:

from @Zzmilanzz's answer I used

try: #python3
    from urllib.request import urlopen
except: #python2
    from urllib2 import urlopen
