This can be achieved using Speech synthesis which is concerned with converting normal words into a human-like speech that we can understand.

Text to Speech Libraries

There some libraries in python that you can use to perform Speech synthesis in just few lines of code;

Text to Speech (TTS) using Pyttsx

pyttsx is a Python package supporting common text-to-speech engines on Mac OS X, Windows, and Linux.

Create app.py then paste the below code and run it

import pyttsx as speech
engine = speech.init()
engine.say('Speech synthesis is process converting text to speech')
engine.runAndWait()

TTS with Espeak

Espeak For those in Linux I would recommend using this library due to it’s easy installation and performance on Linux distro

Installation on Linux
sudo apt-get install espeak
sudo apt-get installl python-espeak
Example of Usage (app.py)
from espeak import espeak as voice
lang = 'en' #en is For English 
voice.set_voice(lang)
voice.synth("I can speak"*5)

gTTS (Google Text-to-Speech), a Python library and CLI tool to interface with Google Translate text-to-speech API

Installation
pip install gTTS
Example of Usage (app.py)
from gtts import gTTS
tts = gTTS('Speech synthesis using Google speech engine ')
tts.save('music.mp3')

TTS with Microsoft Speech Engine (SAPI)

Microsoft Speech Engine has a python wrapper to its Text to speech Engine which works only in Windows.

Installation
pip install pypiwin32
Example of Usage (app.py)
import win32com.client as mouth
voice = mouth.Dispatch("SAPI.SpVoice") 
word_to_say = "Microsoft was founded by Bill gates "
voice.Speak(word_to_say)
