It is advised that the user has prior knowledge of python and some command on basic Python modules. Some of the module we use are standard ones, while the ones that we have to import are as follows:<\/p>\n
pip install wolframalpha\r\npip install pyttsx3\r\npip install wikipedia\r\npip install winshell\r\npip install pyjokes\r\npip install smtplib\r\npip install twilio\r\npip install beautifulsoup4\r\npip install tk<\/pre>\nSteps to build the Voice Assistant Project using Python<\/h3>\n
We will be following the below steps to build the voice assistant:<\/p>\n
1. First, we import the modules.<\/p>\n
2. Followed by this, we will be building the voice assistant and create function to speak using the voice engine<\/p>\n
3. Then we create the function to wish, get the name of the user and command<\/p>\n
4. Next, we will be writing functions to do various tasks like getting a weather report, sending mail, etc.<\/p>\n
5. Finally, we write the while loop to run the assistant continuously. In which we take the command and check the command to do the respective task using if else statements.<\/p>\n
6. Note that all the tasks we include are our choice. Depending on your comfort, you can add required commands and remove the ones that you don\u2019t need. And make the voice assistant based on your suitability.<\/p>\n
1. Import the modules<\/h3>\n
The first step is to import all the required modules. We are importing the ones that we discussed above.<\/p>\n
import subprocess\r\nimport wolframalpha\r\nimport pyttsx3\r\nimport random\r\nimport speech_recognition as sr\r\nimport wikipedia\r\nimport webbrowser\r\nimport os\r\nimport winshell\r\nimport pyjokes\r\nimport json\r\nimport feedparser\r\nimport smtplib\r\nimport datetime \r\nimport requests\r\nfrom twilio.rest import Client\r\nfrom bs4 import BeautifulSoup\r\nimport win32com.client as wincl\r\nfrom urllib.request import urlopen<\/pre>\n2. Building the Voice Assistant and write function to speak<\/h3>\n
Next, we will be getting the voice assistant using the module pyttsx3. We set the appropriate properties to the engine and write a function to speak the text sent as input.<\/p>\n
voiceEngine = pyttsx3.init('sapi5')\r\nvoices = voiceEngine.getProperty('voices')\r\nvoiceEngine.setProperty('voice', voices[1].id)\r\n\r\ndef speak(text):\r\n voiceEngine.say(text)\r\n voiceEngine.runAndWait()<\/pre>\n3. Writing functions to wish, get username, and get command<\/h3>\n
In this step, we will be creating the required function, the ones that we use to wish initially, get the name and take command after every completion of a task.<\/p>\n
1. In the wish() function, we are calculating time and then based on that we are doing the appropriate greeting. Followed by, we are introducing the assistant.<\/p>\n
2. In the getName() function, we are getting the name of the user as a command and then storing it in the global variable named \u2018uname\u2019.<\/p>\n
3. And in the function getCommand(), we will be recognizing the microphone, listen to the user\u2019s voice, and format it to a text form.<\/p>\n
def wish():\r\n print(\"Wishing.\")\r\n time = int(datetime.datetime.now().hour)\r\n global uname,asname\r\n if time>= 0 and time<12:\r\n speak(\"Good Morning sir or madam!\")\r\n\r\n elif time<18:\r\n speak(\"Good Afternoon sir or madam!\")\r\n\r\n else:\r\n speak(\"Good Evening sir or madam!\")\r\n\r\n asname =\"Jasper 1 point o\"\r\n speak(\"I am your Voice Assistant from DataFlair,\")\r\n speak(asname)\r\n print(\"I am your Voice Assistant,\",asname)\r\ndef getName():\r\n global uname\r\n speak(\"Can I please know your name?\")\r\n uname = takeCommand()\r\n print(\"Name:\",uname)\r\n speak(\"I am glad to know you!\")\r\n columns = shutil.get_terminal_size().columns\r\n speak(\"How can i Help you, \")\r\n speak(uname)\r\n\r\ndef takeCommand():\r\n recog = sr.Recognizer()\r\n \r\n with sr.Microphone() as source:\r\n print(\"Listening to the user\")\r\n recog.pause_threshold = 1\r\n userInput = recog.listen(source)\r\n\r\n try:\r\n print(\"Recognizing the command\")\r\n command = recog.recognize_google(userInput, language ='en-in')\r\n print(f\"Command is: {command}\\n\")\r\n\r\n except Exception as e:\r\n print(e)\r\n print(\"Unable to Recognize the voice.\")\r\n return \"None\"\r\n\r\n return command<\/pre>\n4. Creating functions for some of the tasks<\/h3>\n
Here we will be creating functions to send mail, get the weather report, and get news.<\/p>\n
1. In the sendEmail() function, we are connecting to the mail server, logging in using appropriate credentials, and sending the mail to the required receiver.<\/p>\n
2. In the function getWeather(), we are getting the url for the required city. Then getting the request, converting it to json form and getting required details by indexing.<\/p>\n
3. In the getNews() function, we are getting the request of the new website, then scraping the information using the bs4 module. Then, getting the main headlines.<\/p>\n
def sendEmail(to, content):\r\n print(\"Sending mail to \", to)\r\n server = smtplib.SMTP('smtp.gmail.com', 587)\r\n server.ehlo()\r\n server.starttls()\r\n #paste your email id and password in the respective places\r\n server.login('your email id', 'password') \r\n server.sendmail('your email id', to, content)\r\n server.close()\r\n\r\ndef getWeather(city_name):\r\n cityName=place.get() #getting input of name of the place from user\r\n baseUrl = \"http:\/\/api.openweathermap.org\/data\/2.5\/weather?\" #base url from where we extract weather report\r\n url = baseUrl + \"appid=\" + 'd850f7f52bf19300a9eb4b0aa6b80f0d' + \"&q=\" + cityName \r\n response = requests.get(url)\r\n x = response.json()\r\n\r\n #If there is no error, getting all the weather conditions\r\n if x[\"cod\"] != \"404\":\r\n y = x[\"main\"]\r\n temp = y[\"temp\"]\r\n temp-=273 \r\n pressure = y[\"pressure\"]\r\n humidity = y[\"humidity\"]\r\n desc = x[\"weather\"]\r\n description = z[0][\"description\"]\r\n info=(\" Temperature= \" +str(temp)+\"\u00b0C\"+\"\\n atmospheric pressure (hPa) =\"+str(pressure) +\"\\n humidity = \" +str(humidity)+\"%\" +\"\\n description = \" +str(description))\r\n print(info)\r\n speak(\"Here is the weather report at\")\r\n speak(city_name)\r\n speak(info)\r\n else:\r\n speak(\" City Not Found \")\r\n\r\ndef getNews():\r\n try:\r\n response = requests.get('https:\/\/www.bbc.com\/news')\r\n \r\n b4soup = BeautifulSoup(response.text, 'html.parser')\r\n headLines = b4soup.find('body').find_all('h3')\r\n unwantedLines = ['BBC World News TV', 'BBC World Service Radio',\r\n 'News daily newsletter', 'Mobile app', 'Get in touch']\r\n\r\n for x in list(dict.fromkeys(headLines)):\r\n if x.text.strip() not in unwantedLines:\r\n print(x.text.strip())\r\n except Exception as e:\r\n print(str(e))<\/pre>\n5. The main code to run the assistant<\/h3>\n
Finally, we are creating the code to run the voice assistant. First, we are creating the global names, wishing and getting the username. Next, in a while loop we continuously get the command, check the command using the if-else ladder and do corresponding operation.<\/p>\n
if __name__ == '__main__':\r\n\r\n uname=''\r\n asname=''\r\n os.system('cls')\r\n wish()\r\n getName()\r\n print(uname)\r\n\r\n while True:\r\n\r\n command = takeCommand().lower()\r\n print(command)\r\n\r\n if \"jarvis\" in command:\r\n wish()\r\n \r\n elif 'how are you' in command:\r\n speak(\"I am fine, Thank you\")\r\n speak(\"How are you, \")\r\n speak(uname)\r\n\r\n elif \"good morning\" in command or \"good afternoon\" in command or \"good evening\" in command:\r\n speak(\"A very\" +command)\r\n speak(\"Thank you for wishing me!
