Voice command calculator in Python

Here we are planning to say “forty eight multiplied by sixty seven” and get the math done for which we will have to do go through the following steps

1. install packages
   speech_recognition and win32com.client

   pip install win32com.client
   pip install speech_recognition
   

    

2. access mic

   a = sr.Recognizer()
   with sr.Microphone() as source:

    

3. correct the background noise

   a.adjust_for_ambient_noise(source)
       audio = a.listen(source)

    

4. store the voice in a .wav file

   with open("recorded_audio.wav", "wb") as f:
               f.write(audio.get_wav_data())

    

5. read convert .wav into text

   text = a.recognize_google(audio)
           bolo.speak("You said: " + text)

    

6. text into integer
7. perform the math
8. invoke the SAPI.spVoice and speak the final answer

   bolo = win32com.client.Dispatch("SAPI.SpVoice")
   bolo.speak("")

    

Thus the final code for the whole program to give an audio input, process the math and recieve the audio output is:

import speech_recognition as sr
import win32com.client


bolo = win32com.client.Dispatch("SAPI.SpVoice")
bolo.speak("Speak your question")
a = sr.Recognizer()
with sr.Microphone() as source:
    a.adjust_for_ambient_noise(source)
    audio = a.listen(source)
    try:
        text = a.recognize_google(audio)
        bolo.speak("You said: " + text)
        print("You said: " , text)
        with open("recorded_audio.wav", "wb") as f:
            f.write(audio.get_wav_data())
    except Exception as e:
        print("Error: " + str(e))
l=text.split()
print(l)
if l[1]=='+':
    s=int(l[0])+int(l[2])
    bolo.speak("the sum is "+str(s))
    print("the sum is ",str(s))
elif l[1]=='-':
    s=int(l[0])-int(l[2])
    bolo.speak("the difference is "+str(s))
    print("the difference is ",str(s))
elif l[1].capitalize()=='X':
    s=int(l[0])*int(l[2])
    bolo.speak("the product is "+str(s))
    print("the product is "+str(s))
elif l[1]=='/':
    s=round(int(l[0])/int(l[2]),5)
    bolo.speak("the quotient is"+str(s))
    print("the quotient is"+str(s))
else:
    bolo.speak("Sorry, Either you are not clear or I am a bit dumb")
