If you get installation errors , make sure you first upgrade your wheel version using :
pip install --upgrade wheel
Features :
- ✨Fully OFFLINE text to speech conversion
- 🎈 Choose among different voices installed in your system
- 🎛 Control speed/rate of speech
- 🎚 Tweak Volume
- 📀 Save the speech audio as a file
- ❤️ Simple, powerful, & intuitive API
Linux installation requirements :
-
If you are on a Linux system and if the voice output is not working, then :
Install espeak-ng and libespeak1 as shown below:
sudo apt update && sudo apt install espeak-ng libespeak1
Usage :
import pyttsx3
engine = pyttsx3.init()
# For Mac, If you face error related to "pyobjc" when running the `init()` method :
# Install 9.0.1 version of pyobjc : "pip install pyobjc>=9.0.1"
engine.say("I will speak this text")
engine.runAndWait()
Single line usage with speak function with default options
import pyttsx3
pyttsx3.speak("I will speak this text")
Changing Voice , Rate and Volume :
import pyttsx3
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')
engine.runAndWait()
