Python tutorial converting speech to text using python script

In this article i will explain you how you can convert any voice data to text format in python

Step 1: Install necessary python library which gonna help in converting speech to text

Install SpeechRecognition python module

   #To install speech recogntion module if you are using python 3
   sudo pip3 install SpeechRecognition

Install pyaudio python module linux ubuntu user

   #To install pyaudio if you are using linux ubuntu run this command
   sudo apt-get install portaudio19-dev python-pyaudio

   #After running above command run the following command
   sudo pip3 install PyAudio

Install pyaudio python module windows and macos user

   pip3 install PyAudio

Step 2: Once all the required python library installed copy paste the following code in to your python script file

import speech_recognition as sr

sample_rate = 48000

chunk_size = 2048

r = sr.Recognizer()

#This will return all the list of input devices on your computer in the form of list you can select any input device and
#and pass the index of the device as first argument of sr.Microphone function
mic_list = sr.Microphone.list_microphone_names()

with sr.Microphone(0, sample_rate = sample_rate, chunk_size = chunk_size) as source:
    #this will adjust the energy threshold based on the surrounding noise level
    r.adjust_for_ambient_noise(source)
    print ("Tell Something")
    #listens for the user's input
    audio = r.listen(source)

    try:
        text = r.recognize_google(audio)
        print ("you said: ",text)

    #error occurs when not understand what was said
    except sr.UnknownValueError:
        print("Not able to understand your audio")

    except sr.RequestError as e:
        print("Some error occured; {0}".format(e))

Step 3: Run the python script

#In case if you are using python 3 you need to use python3 instead of python to run your script
python your_script.py
