confused with subprocess.Popen

for a certain app, i used to use a command:
os.system("soundwrapper espeak -f line.txt")
now, if i wanted to kill espeak, i would have to run:
os.system("killall espeak")
since the subprocess module allows sending SIGKILL to the process, i
decided to switch to using it. However i cant pass the spaced out
arguments to it. For example:
a=subprocess.Popen("soundwrapper espeak -f line.txt")
results in a OSError, no such file or directory.
How do i use the Popen function?
