Don’t Buy Alexa – Build Your Own ALEXA using Python¶
Alexa Has Only 2 Tasks:¶
1. Listening¶
Listening to your command is the most basic functionality of any virtual assistant, like: “Hey Alexa, play music,” “Hey Alexa, what’s the time?”
Alexa has to listen to your command, understand it, and then do some action.
2. Speaking¶
Once Alexa listens and understands your command, it performs some action based on it. While doing that, it responds to you by speaking otherwise it’ll be jobless.

4 . Speech Recognition in Python using Google Speech API¶
This library performs speech recognition. It’ll help the assistant listen to our commands, understand them, and act accordingly. Speech Recognition is an important feature in several applications used such as home automation, artificial intelligence, etc
Note: Kindly use python 3.6.8 because pyaudio doesn’t works on python version greater than 3.6
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:
print("Say Something:")
audio = r.listen(source)
text = r.recognize_google(audio)
print("You Said:",text)
5. Data and Time¶
import datetime
time = datetime.datetime.now().strftime('%I:%m %p')
print(time)
import datetime
date = datetime.datetime.now().strftime('%d %b %Y')
print(date)
6. Get your City Temperature¶
api_key = "e226a2eaa720614632c86b91ec9868ee"
base_url = "https://api.openweathermap.org/data/2.5/weather?"
city_name="goa"
print(city_name)
complete_url = base_url + "q=" + city_name + "&appid=" + api_key
response = requests.get(complete_url)
x = response.json()
if x["cod"] != "404":
y = x["main"]
current_temperature = y["temp"]
current_pressure = y["pressure"]
current_humidiy = y["humidity"]
z = x["weather"]
weather_description = z[0]["description"]
print(" Temperature (in Celcius unit) = " +
str(int(current_temperature)-273.15) +
"\n atmospheric pressure (in hPa unit) = " +
str(current_pressure) +
"\n humidity (in percentage) = " +
str(current_humidiy) +
"\n description = " +
str(weather_description))
else:
print(" City Not Found ")
7. Read Today’s News¶
import requests
import json
a=requests.get("https://newsapi.org/v2/top-headlines?country=in&apiKey=9fe4be099c6c417a8c00b56ee67f9db5")
b=json.loads(a.text)
for i in range(10):
my_data=b['articles'][i]['title']
print ("Title:",i+1,my_data)
8. Crack Jokes¶
