Use subprocess.check_output (new in python 2.7). It will suppress stdout and raise an exception if the command fails. (It actually returns the contents of stdout, so you can use that later in your program if you want.) Example:

import subprocess try: subprocess.check_output(['espeak', text]) except subprocess.CalledProcessError: # Do something 

You can also suppress stderr with:

 subprocess.check_output(["espeak", text], stderr=subprocess.STDOUT) 

For earlier than 2.7, use

import os import subprocess with open(os.devnull, 'w') as FNULL: try: subprocess._check_call(['espeak', text], stdout=FNULL) except subprocess.CalledProcessError: # Do something 

Here, you can suppress stderr with

 subprocess._check_call(['espeak', text], stdout=FNULL, stderr=FNULL) 

Use subprocess.check_output (new in python 2.7). It will captures stdout as the return value of the function, which both prevents it from being sent to standard out and makes it availalbe for you to use programmatically. Like subprocess.check_call, this raises an exception if the command fails, which is generally what you want from a control-flow perspective. Example:

import subprocess try:   output = subprocess.check_output(['espeak', text]) except subprocess.CalledProcessError: # Handle failed call 

You can also suppress stderr with:

 output = subprocess.check_output(["espeak", text], stderr=subprocess.STDOUT) 

For earlier than 2.7, use

import os import subprocess with open(os.devnull, 'w') as FNULL: try:   output = subprocess._check_call(['espeak', text], stdout=FNULL) except subprocess.CalledProcessError: # Handle failed call

  output = subprocess._check_call(['espeak', text], stdout=FNULL, stderr=FNULL)
