importpyttsx3
engine = pyttsx3.init() # object creation

# RATE
rate = engine.getProperty('rate') # getting details of current speaking rate
print (rate) # printing current voice rate
engine.setProperty('rate', 125) # setting up new voice rate

# VOLUME
volume = engine.getProperty('volume') # getting to know current volume level (min=0 and max=1)
print (volume) # printing current volume level
engine.setProperty('volume',1.0) # setting up volume level between 0 and 1

# VOICE
voices = engine.getProperty('voices') # getting details of current voice
#engine.setProperty('voice', voices[0].id) # changing index, changes voices. o for male
engine.setProperty('voice', voices[1].id) # changing index, changes voices. 1 for female

engine.say("Hello World!")
engine.say('My current speaking rate is ' + str(rate))
engine.runAndWait()
engine.stop()

# Saving Voice to a file
# On Linux, make sure that 'espeak-ng' is installed
engine.save_to_file('Hello World', 'test.mp3')
