Voice Assistant using python

As we know Python is a suitable language for scriptwriters and developers. Let’s write a script for Voice Assistant using Python. The query for the assistant can be manipulated as per the user’s need.
Speech recognition is the process of converting audio into text. This is commonly used in voice assistants like Alexa, Siri, etc. Python provides an API called SpeechRecognition to allow us to convert audio into text for further processing. In this article, we will look at converting large or long audio files into text using the SpeechRecognition API in python.

Modules needed

Subprocess:- This module is used to get system subprocess details used in various commands i.e Shutdown, Sleep, etc. This module comes built-in with Python.
WolframAlpha:- It is used to compute expert-level answers using Wolfram’s algorithms, knowledgebase and AI technology. To install this module type the below command in the terminal.

pip install wolframalpha

Pyttsx3:- This module is used for the conversion of text to speech in a program it works offline. To install this module type the below command in the terminal.
pip install pyttsx3
Tkinter:- This module is used for building GUI and comes inbuilt with Python. This module comes built-in with Python.
Wikipedia:- As we all know Wikipedia is a great source of knowledge just like Lazyroar we have used the Wikipedia module to get information from Wikipedia or to perform a Wikipedia search. To install this module type the below command in the terminal.

pip install wikipedia

Speech Recognition:- Since we’re building an Application of voice assistant, one of the most important things in this is that your assistant recognizes your voice (means what you want to say/ ask). To install this module type the below command in the terminal.

pip install SpeechRecognition

Web browser:- To perform Web Search. This module comes built-in with Python.
Ecapture:- To capture images from your Camera. To install this module type the below command in the terminal.

pip install ecapture

Pyjokes:- Pyjokes is used for the collection of Python Jokes over the Internet. To install this module type the below command in the terminal.
pip install pyjokes
Datetime:- Date and Time are used to showing Date and Time. This module comes built-in with Python.
Twilio:- Twilio is used for making calls and messages. To install this module type the below command in the terminal.

pip install twilio

Requests: Requests is used for making GET and POST requests. To install this module type the below command in the terminal.
pip install requests
BeautifulSoup: Beautiful Soup is a library that makes it easy to scrape information from web pages. To install this module type the below command in the terminal.

pip install beautifulsoup4

Note: You can remove some of the import files if you don’t want to get that feature as here Twilio for making calls and messages if you don’t want to use that you can simply remove that function.

Implementation
Import the below libraries.

Python3

import subprocess
import wolframalpha
import pyttsx3
import tkinter
import json
import random
import operator
import speech_recognition as sr
import datetime
import wikipedia
import webbrowser
import os
import winshell
import pyjokes
import feedparser
import smtplib
import ctypes
import time
import requests
import shutil
from twilio.rest import Client
from clint.textui import progress
from ecapture import ecapture as ec
from bs4 import BeautifulSoup
import win32com.client as wincl
from urllib.request import urlopen

Now we will set our engine to Pyttsx3 which is used for text to speech in Python and sapi5 is a Microsoft speech application platform interface we will be using this for text to speech function.

Python3

engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
engine.setProperty('voice', voices[1].id)

You can change the voice Id to “0” for the Male voice while using assistant here we are using a Female voice for all text to speech

Python3

def speak(audio):
    engine.say(audio)
    engine.runAndWait()
 
def wishMe():
    hour = int(datetime.datetime.now().hour)
    if hour>= 0 and hour<12:
        speak("Good Morning Sir !")
  
    elif hour>= 12 and hour<18:
        speak("Good Afternoon Sir !")  
  
    else:
        speak("Good Evening Sir !") 
  
    assname =("Jarvis 1 point o")
    speak("I am your Assistant")
    speak(assname)
     
 
def username():
    speak("What should i call you sir")
    uname = takeCommand()
    speak("Welcome Mister")
    speak(uname)
    columns = shutil.get_terminal_size().columns
     
    print("#####################".center(columns))
    print("Welcome Mr.", uname.center(columns))
    print("#####################".center(columns))
     
    speak("How can i Help you, Sir")
 
def takeCommand():
     
    r = sr.Recognizer()
     
    with sr.Microphone() as source:
         
        print("Listening...")
        r.pause_threshold = 1
        audio = r.listen(source)
  
    try:
        print("Recognizing...")   
        query = r.recognize_google(audio, language ='en-in')
        print(f"User said: {query}\n")
  
    except Exception as e:
        print(e)   
        print("Unable to Recognize your voice.") 
        return "None"
     
    return query
  
def sendEmail(to, content):
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.ehlo()
    server.starttls()
     
    # Enable low security in gmail
    server.login('your email id', 'your email password')
    server.sendmail('your email id', to, content)
    server.close()

Main Function starts here, we will now call all these functions in the main function.

Python3
