Tech 1 # qrcode
visit: https://pypi.org/project/qrcode/
What is a QR Code?
A Quick Response code is a two-dimensional pictographic code used for its fast readability and comparatively large storage capacity
#### In the code below:First we install qrcode directly from jupyter notebook.Then, after importing the lib, we generate a qrcode, and save it as PNG - Portable Network GraphicsInstall the lib:
!pip install qrcodeCollecting qrcode

Tech 2 # Simplified Answering Machine
To test it please run as much as you like!
Three words or sets of words must exist in the sentence spoken and captured by the microphone:
“HELLO”
“HOW ARE YOU”
“GOODBYE”And wait for the answer 😉
The code:
# Recognizes a greeting
# Get input
words = input("Say something!\n").lower()
# Respond to speech
if "hello" in words:
print("Hello to you too!")
elif "how are you" in words:
print("I am well, thanks!")
elif "goodbye" in words:
print("Goodbye to you too!")
else:
print("Huh?")Say something! hello Hello to you too!
Tech 3 # Speech Recognition in Python
There are several technologies available on the market. Let's bring the google solution, shall we?How to Convert Speech to Text in PythonCMU Sphinx (offline)
Google Speech Recognition
Google Cloud Speech API
Wit.ai
Microsoft Bing Voice Recognition
Houndify API
IBM Speech To Text
Snowboy Hotword Detection (offline)In the code below:
First we install pyaudio and SpeechRecognitions from google.
Then, obtain audio from the microphone.
And finaly, Recognize speech using Google Speech Recognition
Say something and wait the answer 👈
!pip install pyaudio
!pip install SpeechRecognitionCollecting pyaudio

Collecting SpeechRecognition
Using cached SpeechRecognition-3.8.1-py2.py3-none-any.whl (32.8 MB)
Installing collected packages: SpeechRecognition
Successfully installed SpeechRecognition-3.8.1The code:
import speech_recognition
# Obtain audio from the microphone
recognizer = speech_recognition.Recognizer()
with speech_recognition.Microphone() as source:
print("Say something:")
audio = recognizer.listen(source)# Recognize speech using Google Speech Recognition
print("You said:")
print(recognizer.recognize_google(audio))Say something:
You said:
Shoe StopHere we mixed the two codes above and see what happened!
To test it please run as much as you like!
Three words or sets of words must exist in the sentence spoken and captured by the microphone:
“HELLO”
“HOW ARE YOU”
“GOODBYE”The code:

recognizer = speech_recognition.Recognizer()
with speech_recognition.Microphone() as source:
print("Say something:")
audio = recognizer.listen(source)# Recognize speech using Google Speech Recognitionwords = recognizer.recognize_google(audio)# Respond to speech
if "hello" in words:
print("Hello to you too!")
elif "how are you" in words:
print("I am well, thanks!")
elif "goodbye" in words:
print("Goodbye to you too!")
else:
print("Huh?")Say something:
Goodbye to you too!Now say what’s your name
import re
import speech_recognition
# Obtain audio from the microphone
recognizer = speech_recognition.Recognizer()
with speech_recognition.Microphone() as source:
print("Say something:")
audio = recognizer.listen(source)# Recognize speech using Google Speech Recognition
words = recognizer.recognize_google(audio)# Respond to speech
matches = re.search("my name is (.*)", words)
if matches:
print(f"Hey, {matches[1]}.")
else:
print("Hey, you.")Say something:
Hey, J-3.Tech 4 # Speech Recognition in Python
visit: https://pypi.org/project/pyttsx3/
It Supports multiple TTS engines, including Sapi5, nsss, and espeak.

Requirement already satisfied: pywin32 in c:\users\giljr\appdata\roaming\python\python39\site-packages (from pyttsx3) (303)The code:
import pyttsx3
engine = pyttsx3.init()
engine.say("hello, world")
engine.runAndWait()You will hear the sentence written above on your computer speakers.
import pyttsx3
engine = pyttsx3.init()
name = input("What's your name? ")
engine.say(f"hello, {name}")
engine.runAndWait()What's your name? j3And finally:
import pyttsx3
engine = pyttsx3.init()
engine.say("This was CS50")
engine.say("That's it!")
engine.say("Thanks to: DAVID MALAN from HAVARD CS50 COURSE")
engine.runAndWait()The credits goes to:
