Voice Command Assistant

Hey techies, I hope and wish u have a good day today, welcome to this week's article. Today, I am going to make you gain knowledge on "voice assistant with python". Hope you are loving my articles and I appreciate it if you show a response by commenting, liking or even sharing on your socials. I am focusing more on Python so I also suggest you to read my previous articles on Python.

1.) What is Voice Command Assistant?

• A voice command assistant is a software application that allows users to interact with their devices using natural language voice commands. This assistant can perform a variety of tasks, such as setting reminders, playing music, making phone calls, opening and closing tabs and controlling smart home devices.

• Some popular examples of voice command assistants include (Amazon's Alexa, Google Assistant, and Apple's Siri).

2.) Tips and tricks

• Use natural language: Speak to your voice command assistant as you would to a person, using natural language and complete sentences. This will make it easier for the assistant to understand your commands and respond appropriately.

• Create custom commands: Many voice command assistants allow you to create custom commands for specific tasks or actions. This can save time and make it easier to perform certain tasks.

  Ex: in google assistant, we can customize our daily routine.

  Google>settings>assistant>Routines>customize how u want

• Use the assistant for hands-free tasks: You can use your voice command assistant to control smart home devices like lights, dustbins, mobiles. It will make your life more comfortable just with a single command.

• Use reminders and alarms: Set reminders and alarms to keep yourself on track throughout the day. You can set reminders for appointments, tasks, or even to take medication.

• Enable multiple-language support: Some voice command assistants support multiple languages like(google..etc), which can be helpful if you speak more than one language, or if you want to use the assistant in a multilingual environment.

• Keep it updated: Make sure to keep your voice command assistant updated with the latest software, this will ensure that you have the latest features and security fixes.

• Use it as a personal assistant: You can use your voice command assistant to manage your schedule, check the weather, and even to order groceries or other items and make your life simpler.

3.) Here is the code for the assistant which i worked for my project.

Creating a voice command assistant typically involves several steps, including:

• Speech recognition

• analyzing the text generated by the speech recognition

• Task execution

• --install these modules inside the pyhon compilers like "PYCHAM" or "VS CODE" inside the (terminal)---------.

pip install wikipedia
pip install SpeechRecognition
pip install wolframalpha
pip install ecapture
pip install twilio
pip install beautifulsoup4

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.

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

Select any voice u want from here (Male/Femlae)

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
