I am trying to execute espeak using python using an MBROLA voice "us1".
from subprocess import call
call(["espeak","-v mb-us1","Hello, I am espeak"])
and the following error appear'
Failed to read voice ' mb-us1'
but it works fine with:
os.system("espeak -v mb-us1 'hello, I am espeak'")
You hava to split "-v mb-us1" in two list elements.
from subprocess import call
call(["espeak", "-v", "mb-us1", "Hello, I am espeak"])
The nth element of the list will be treated a the nth argument of the subprocess call.
In your case "-v mb-us1" was treated as a single argument instead of two seperate arguments.
