How to hide output of subprocess

I’m using eSpeak on Ubuntu and have a Python 2.7 script that prints and speaks a message:

import subprocess
text="Hello World."
print text
subprocess.call(['espeak', text])

eSpeak produces the desired sounds, but clutters the shell with some errors (ALSA lib…, no socket connect) so i cannot easily read what was printed earlier. Exit code is 0.

Unfortunately there is no documented option to turn off its verbosity, so I’m looking for a way to only visually silence it and keep the open shell clean for further interaction.

How can I do this?
