My Examples

​

Here is an example module from my personal collection, it is a basic internet search module. It works like this, you say something like search (website) for (query) and the module will open that website and display the result as if you manually opened and search the site yourself.

​

The explanations for each line will be in blue

​

import speech_recognition

Allows the assistant to hear what you say

import pyttsx3

Allows the assistant to talk back to you

import pywhatkit

Allows the assistant to search google and other sites

import wikipedia

Searches Wikipedia

import webbrowser

Used to open your default web browser

def takeCommand():

Creates the function, this specific ones listens for verbal input

    r = speech_recognition.Recognizer()

Processes and understands audio

    with speech_recognition.Microphone() as source:

Activates the microphone for verbal input

        print('Listening...')

Displays the text inside of the ()

        r.pause_threshold = 1

How many seconds the assistant will wait after verbal input stops

        r.energy_threshold = 300

This is  the microphone sensitivity, the higher the number, the less background noise is picked up

        audio = r.listen(source,0,4)

Listens to the mic and records audio

• Source: Mic input

• 0: Wait time before listening in seconds

• 4: How long the listening time is in seconds

    try:

Catches errors safely

        print("Understanding...")

Displays the text inside of the ()

        query  = r.recognize_google(audio,language='en-en')

Uses the Google speech recognition to convert the verbal input into text

        print(f"You Said: {query}\n")

Diplays the text inside of the ()

    except Exception as e:

This runs if an error happens, usually verbal input not getting recognized

        print("Apologies, please say that again")

Diplays the text inside of the ()

        return "None"

Returns NONE if the speech recognition fails

    return query

Returns the recognized speech back to the module

query = takeCommand().lower()

Converts the result to lowercase to make the command check easier

engine = pyttsx3.init("sapi5")

Uses the Microsoft Windows voice system

voices = engine.getProperty("voices")

Gets the list of avaiable voices

engine.setProperty("voice", voices[3].id)

Selects one of the avaiable voices, change the "3" to use a different voice

engine.setProperty("rate",175)

Speed that the assistant speaks

def speak(audio):

Makes the assistant speak

    engine.say(audio)

Adds the verbal response to the que

    engine.runAndWait()

Runs the speech engine and waits until the verbal input is finished

def searchGoogle(query):

Creates the function that will perform the Google search

    if "google" in query:

Listens for the trigger phrase to determine what website to use

        import wikipedia as googleScrap

Imports Wikipedia but renames it to googleScrap

        query = query.replace("rise","")

Removes the word "rise" from the search

        query = query.replace("google search","")

Removes the phrase "google search" from the command

        query = query.replace("google","")

Removes "Google" to get a proper search

        speak("This is what I found on google")

Verbally tells the user the search is complete

        try:

Begins another block for error handling

            pywhatkit.search(query)

Performs the Google search in the borwser

            result = googleScrap.summary(query,1)

Retrieves a summary from Wikipedia for the search

            speak(result)

Verbally tells the user the result

        except:

Runs if the search fails

            speak("No speakable output available")

Verbally tells the user that the search result was not readable

The following follow the same rules as the Google portion of the code

def searchYoutube(query):

    if  "youtube" in query:

        speak("This is what I found")

        query = query.replace("youtube search","")

        query = query.replace("youtube","")

        query = query.replace("rise","")

        web = "https://www.youtube.com/results?search_query=" + query

        webbrowser.open(web)

        pywhatkit.playonyt(query)

        speak("Done, Boss")

       

def searchWikipedia(query):

    if  "wikipedia" in query:

        speak("Searching Wikipedia...")

        query = query.replace("wikipedia search","")

        query = query.replace("search wikipedia","")

        query = query.replace("rise","")

        results = wikipedia.summary(query,sentences = 2)

        speak("According to Wikipedia..")

        print(results)

        speak(results)
