Python text to speech conversion

Python text to speech conversion

In order to convert a given text to speech, In python, we use `pyttsx3` module. pyttsx3 is a text-to-speech conversion library in Python. It works offline, and is compatible with both Python 2 and 3.

Use this command for installation:

pip install pyttsx3

Usage:

First we need to import the module `pyttsx3` using import statement. Then we need to initialize it using `init()` function.

After initializing, we need the program to speak using `say()` function. This takes two arguments as below:

say(text, name string)

text : Any text you wish to hear.
name : To set a name for this speech. (optional)

To run the speech we use runAndWait(). The say() function texts won’t be said unless the interpreter encounters runAndWait().

Example Code #1:

# importing the pyttsx library 
import pyttsx3 
  
# initialisation 
engine = pyttsx3.init() 
  
# testing 
engine.say("Hello world")
engine.say("My first code on text-to-speech")
engine.runAndWait() 



We can also change voice (Male or Female) and manage volume control, Also, we can increase or decrease voice rate.

Example Code #2:

Changing Voice, Volume and Voice rate:

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.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()
engine.stop()
