voice.rate(3)

Traceback (most recent call last):

voice.rate(3)
AttributeError: 'Sapi' object has no attribute 'rate'

I'm trying to switch to "Ivona 2 Joey" but not sure how to do it.

import tts.sapi
directory= 'D:\Google Drive\python\'
voice = tts.sapi.Sapi()
voice.set_voice("Ivona 2 Joey")
voice.create_recording(directory+'hello.wav', "Hello")

error:

Voice not found

Traceback (most recent call last):

voice.set_voice("Ivona 2 Joey")

self.voice.Voice = self.get_voices(voice)[0]
IndexError: list index out of range

Using winsdk and Windows.Media.SpeechSynthesis, it's posible to select more voices. In my system, this program only detects David and Zira, while the UWP API has Mark too.

import tts.sapi

directory= 'D:\Google Drive\python\'
voice = tts.sapi.Sapi()
voice.set_voice("IVONA 2 Joey")
voice.create_recording(directory+'hello.wav', "Hello")

I can write to this directory with other python scripts, but not sure why I can't do it here.

sapitts doesn't close the stream after creating the file, so the code only works twice unless you have to restart the whole program,

here's my post on stackoverflow that shows how to fix it

(I'm using this library for the first time (thanks!), so I may be doing something wrong.)

All three sound files generated seem to have the same volume:

import tts.sapi
voice = tts.sapi.Sapi()
voice.set_voice("CUSTOM-HUNGARIAN-VOICE")
voice.voice.Volume = 0
voice.create_recording('test_silent.wav', u'görög ábécé')
voice.voice.Volume = 50
voice.create_recording('test_normal.wav', u'görög ábécé')
voice.voice.Volume = 100
voice.create_recording('test_loud.wav', u'görög ábécé')

I've tried voice.Volume instead of voice.voice.Volume, but same result.
