One question of this type is previously asked but is not very helpful. I am using version Python3.8 in Windows 10 OS. I am getting an error, KeyError: 'sapi5'. dont know why this error is occurring. Please have a look at the below code given . My code is-
import pyttsx3
engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
engine.setProperty('voices', voices[0].id)
The Error is quite big. can anyone help me?
