listening to user input even after opening an application in mac

[sharma16aug]

hi i'm writing a script to simply open and close an application on mac using python. using my voice i want to open the specified application and close it when told so. i'm using speech recognition for giving voice commands and using subprocess to open an application by this method :

subprocess.call(
    ["/usr/bin/open", "-W", "-n", "-a", "/Applications/"+name+".app"]
    )

i can open the application but after opening the application, my main program stops listening. I want it to listen my voice even after opening the application so that i can close it with the voice command.
here's the listen code:- 

audio = re.listen(source)

            try:
                value=re.recognize_google(audio)
                value=value.strip().split()
                name=" ".join(value[1:])
                if value[0] in OPEN_COGNATES:
                    speak(opCl.openCmd(name))
                    pass
                elif value[0] in CLOSE_COGNATES:
                    speak(opCl.closeCmd(name))
                    pass
                else:
                    pass

openCmd contains this code only :

subprocess.call(
        ["/usr/bin/open", "-W", "-n", "-a", "/Applications/"+name+".app"]
        )

closeCmd contains this command for closing the application :

subprocess.call(['osascript', '-e', 'tell application "'+name+'" to quit'])

can anybody help me. Also i'm quite naive in this. Thank you in advance. 
Even if somebody could tell me how i can do it, that would be beneficial too.

my main program stops listening

What is re? the regex module or another module? Does this listen command create a new thread to continue listening or are you suppose to make a while loop to keep listening?

re is a recogniser object for speech. i'm currently listening it under a while loop. listening it on another thread, will it solve the problem ?

Hello!
Why is that indentation after audio = re.listen(source)? 
Do some tests. If audio stores all the data which flows from the microphone do this mean that you try to recognize and run the open command, again and again, if you send it to google. Does google stop when returns the first word? Does that recognizing speech module run the listening in a separate thread? The audio variable has to be some kind of FIFO file object. 
Get the data from that file and throw it to google, try to catch the response and run the command as you did it already in the continuous while loop.

I can't give you an example of all that because I never used tmpfile module before. I don't know this recognizing speech module and have no time to look at it right now. I hope this is pointing to a right direction

##print listen()

i dont know how to give here indented code. but consider the code is error free, as it is. There is no error either from google speech engine or syntactically. but the thing is after opening an application, the application blocks my code. which i dont want.
