How to play a dynamic string with espeak in python

Question

I am using the espeak library for text to speech conversion.I am able to generate a dynmic sound from a string to do this.

os.system('espeak "hello"')

This works. But what i need is to generate sound from a string. This is what i did

string='hello'
os.system('espeak string')

Just interpolate the string that you want to speak into your command.

>>> string = "Hello"
>>> os.system('espeak "{}"'.format(string))

You could use the subprocess.Popen function if you are accepting user input for the string.

>>> import subprocess
>>> p = subprocess.Popen(['espeak', string])

Use `subprocess.Popen` if you're including user input. – Blender Jul 18 '14 at 04:27
@Blender: Yeah, that's what I would do. But, the OP used os.system. Never mind, I'll add the Popen too. – Sukrit Kalra Jul 18 '14 at 04:29
I meant without `shell=True`: `subprocess.check_call(['espeak', string])`. – Blender Jul 18 '14 at 05:13
The result of `'"{}"'.format(string)` will be escaped. Just `string` will work. – Blender Jul 18 '14 at 05:17

Why not use commands.getoutput() instead?

import commands

def espeak(string):
    output = 'espeak "%s"' % string
    a = commands.getoutput(output)


espeak("Mario Balotelli")
