Pyttsx Voice Gender

Question

Good afternoon, I'm learning and using pyttsx for speech, the thing is that I want to use it as a "female" voice but I can not do it using this code:

import pyttsx as pt
from pyttsx import voice
engine = pt.init()
voices = engine.getProperty('voices')
#engine.setProperty('gender', 'female') # also does not work
engine.setProperty('female', voice.Voice.gender) #not even
engine.setProperty('female', voice.gender) #does not work
engine.setProperty('voice', voices[4].id)
engine.say("Hello World")
engine.runAndWait()


class Voice(object):
    def __init__(self, id, name=None, languages=[], gender=None, age=None):
        self.id = id
        self.name = name
        self.languages = languages
        self.gender = gender
        self.age = age

Answer 1

I used the following code to iterate through the voices to find the female voice

import pyttsx
engine = pyttsx.init()
voices = engine.getProperty('voices')
for voice in voices:
   engine.setProperty('voice', voice.id)
   print voice.id
   engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

On my Windows 10 machine the female voice was HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens\TTS_MS_EN-US_ZIRA_11.0

So I changed my code to look like this

import pyttsx
engine = pyttsx.init()
engine.setProperty('voice', 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens\TTS_MS_EN-US_ZIRA_11.0')
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()
