The SpeechRecognition python module - part 001.

First, you need to install the SpeechRecognition python module for Windows 10:
C:\Python27>cd Scripts
C:\Python27\Scripts>pip install --upgrade  --trusted-host  pypi.python.org  SpeechRecognition
Collecting SpeechRecognition
  Downloading SpeechRecognition-3.6.5-py2.py3-none-any.whl (31.8MB)
    100% |################################| 31.8MB 4.9MB/s
Installing collected packages: SpeechRecognition
  Found existing installation: SpeechRecognition 3.5.0
    Uninstalling SpeechRecognition-3.5.0:
      Successfully uninstalled SpeechRecognition-3.5.0
Successfully installed SpeechRecognition-3.6.5
The next step is the PyAudio python module:
C:\Python27\Scripts>pip install --upgrade  --trusted-host  pypi.python.org  PyAudio
Collecting PyAudio

Installing collected packages: PyAudio
  Found existing installation: PyAudio 0.2.9
    Uninstalling PyAudio-0.2.9:
      Successfully uninstalled PyAudio-0.2.9
Successfully installed PyAudio-0.2.11
Also, this python module can be installed under python version 3.4.1:
C:\Python34\Scripts>pip install SpeechRecognition
Downloading/unpacking SpeechRecognition
Installing collected packages: SpeechRecognition
Successfully installed SpeechRecognition
Cleaning up...
The problem with Python 3.4.x version is PyAudio python module installation.
Anyway, I used the python 2.7.13 version to test this module with a simple python script:
import speech_recognition as sr
import os
print ("HELP: Set your microphone hardware on and try this script")
def active_listen():
    r = sr.Recognizer()
    with sr.Microphone() as src:
        audio = r.listen(src)
    msg = ''
    try:
        msg = r.recognize_google(audio)
        print (msg.lower())
    except sr.UnknownValueError:
        print("Google Speech Recognition could not understand audio")
    except sr.RequestError as e:
        print("Could not request results from Google STT; {0}".format(e))
    except:
        print("Unknown exception occurred!")
    finally:
        return msg.lower()
active_listen()
Just start your microphone hardware on and run the script.
Working well for me this test.

The development with python-instagram .

The python-instagram python module is a Python 2/3 client for the Instagram REST and Search APIs.
This python module requires httplib2, simplejson and six.
Instagram API uses the OAuth2 protocol for authentication, see docs.
C:\Python27\Scripts>pip install --upgrade  --trusted-host  pypi.python.org  
python-instagram

Now about this python module:
C:\Python27>python.exe

If you have an Instagram account then just log in into instagram developer website.
Then fill the issue about your website the phone number and what do you want to build for your application check your agreement with Instagram.
Now you need to use Register Your Application and finally on Register a New Client.
About Register Your Application you need to fill them with data for your application ( basic info: Description, Company Name, Website URL, Contact email).
Select the tab Security and disable the Disable implicit OAuth.

About the token authorizations:

Is given to you with this words:

basic – to read a user’s profile info and media

or needs additional permission:

public_content – to read any public profile info and media on a user’s behalf
follower_list – to read the list of followers and followed-by users
comments – to post and delete comments on a user’s behalf
relationships – to follow and unfollow accounts on a user’s behalf
likes – to like and unlike media on a user’s behalf
The next step is to get access token then you need to add http://localhost link into Security tag from Manage Client.
Use this URL to get the access token by pasting it into your web browser.
https://instagram.com/oauth/authorize/?client_id=[CLIENT_ID_HERE]&redirect_uri=http://localhost&response_type=token&scope=public_content
Into the browser, you will see one page with one button for Authorizing access.
Press this button and into your browser address bar you will get the access token like:
http://localhost/#access_token=################
A simple python script to test it.
from time import sleep
from instagram.client import InstagramAPI

client_id="zzzzz"
client_secret="sssssssssssss"
redirect_uri= "http://xxxxx"
access_token="eeeee"

api = InstagramAPI(client_id=client_id, client_secret=client_secret)
print dir(api)
print api.api_name
To deal with python and Instagram is not very easy for me.
The main reason comes from errors and the Instagram API development way.
Some simple tasks are very hard to do.
