sudo apt update && sudo apt install espeak ffmpeg libespeak1
- β¨Fully OFFLINE text to speech conversion
- π Choose among different voices installed in your system
- π Control speed/rate of speech
- π Tweak Volume
- π Save the speech audio as a file
- β€οΈ Simple, powerful, & intuitive API
import pyttsx3
engine = pyttsx3.init()
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" and "ffmpeg" are installed
engine.save_to_file("Hello World", "test.mp3")
engine.runAndWait()
