With my project,I am aiming to add another dimension to Sugar Labs learning experience by fabricating a speech recognition engine with the help of  Pocketsphinx.I will start with en_US  Hidden Markov Acoustic Model included with Pocketsphinx-0.8.For making it more interactive,we will use a Text-to-Speech engine like eSpeak( Or any better alternative).I will add speech recognition within activities and add a documentation for every activity with certain keywords that will perfrom a task.The basic working of this feature will

      This function returns the final recognized string of the

        This function will check the recognized string hyp

        word=hyp.split()

        if(word[0]="Keyword")

If word[0]="Keyword" ,the corresponding function to perform that task will be called

   −
->We can give commands to do a task or open activities like if we say “Open Terminal”, the terminal activity will be initiated.
+
'''After completion of this project''',
   −
->We can create new activities for communication with which various users can talk to each other like an audio call etc.
+
'''1.''' If we say-”Hi Sugar”,then the speech recognition system will be activated.
   −
->Text and Speech inter-conversion can also be used to create activities like Story Reader. It can be done using available TTS engines like Pico TTS in Android. It will be an interactive experience for young users and their learning will become even more fun.
+
'''2.''' We can give commands to do a task or open activities like if we say “Open Terminal”, the terminal activity will be initiated.
   −
->We can add special support for most commonly used activities like for TurtleBlocks activity,if we say “Forward 20”,it goes 20 units forward.
+
'''3.''' Their will be  special support for '''TurtleBlocks,Terminal,Chat and Browse activity''' like for TurtleBlocks activity,if we say
 +
                                        “Forward 20”,it goes 20 units forward.
   −
->We can also add support for multiple languages and dialects.

In this case,check function will be something like
   −
One of the major advantages of speech recognition will be for people with disabilities who cannot type. Visually impaired users can control many computer tasks and a sense of detachment that they feel from the world can be removed through this system.
+
        def check(self): 
 +
            word=hyp.split()
 +
   
 +
            if(word[0]="Forward")
 +
              s=word[1]
 +
              forward(s)
   −
For setting up voice interface, I will mainly use Python,Java Script and other open source resources like PocketSphinx and Sphinxbase.
+
 
 +
Here,forward function will pass s as variable and change the Turtleblock's file and it will move forward by s units.
 +
We will define many keywords and corresponding functions and if recognised string doesn't match any of them,it will give an error message.
 +
 +
 
 +
 
 +
'''4.'''We can also add support for multiple languages and dialects by using various acoustic models and translation support(Apertium,if needed).
 +
 
 +
 
 +
 
 +
Voice Recognition has been around for over 50 years but it hasn't effectively arrived to the scene in education and learning.With voice interface in SugarLabs,I want to make learning fun for children.Speech Recognition will serve as a assistive technology in many future educational activities.The idea of Voice Interface is not only about implementing Speech recognition but also laying the foundation for Speech understanding where the computer can interpret what we say and answer back with their own ideas. It may sound like science fiction but think if you say “Sugar,open flappy bird game” and it says back - “Their is a reminder in your Calendar activity which says you have an Exam tomorrow.You should better study for that.”.In a matter of few years,it will become a reality.
 +
 
 +
For setting up voice interface, I will mainly use Python and other open source resources like PocketSphinx and Sphinxbase.I will also use acoustic model from various open source resources.

If some time is left,I will work on creating a activity where user can create his/her own acoustic model.It will help reduce the errors in recognizing what the user has to say.

I worked with a senior to develop a Social RSS Reader Application for Android Platform using Facebook GRAPH API in order to synchronize user subscriptions with Facebook News Feed thereby making it possible to receive updates from and send updates to Facebook friends regarding the Application.

I have uploaded it on github https://github.com/bliss-sid/Social-RSS-Reader

I have adequate knowledge of PocketSphinx and Hidden Markov Acoustic Models.I am also doing a course on Cryptography on www.coursera.org. I am keen to work with SugarLabs and put all my efforts to successfully complete this project.
 +
I know that I lack on experience in Open Source but I will surely cover up for that before Community bonding time and work even harder to stay high on your expectations.I have worked pretty hard on this project and I really feel that I am the apt geek for this project.

I have configured speech recognition on my Ubuntu system with Google2Ubuntu.I have also studied the API documentation for the Pocketsphinx speech recognition engine and have learnt how to use it in this project.I am also doing a course on Cryptography on www.coursera.org.

Speech recognition is a ground breaking technology and it will make Sugar Labs more captivating. It will give ease to users as they can do various tasks just by use of speech. Users who are unable to write or see with the help of this application can perform their task like starting an activity or playing a song just by saying. It will lay off foundation to development of new set of activities which use voice interface. The barrier of language difference can also be removed with multiple language support.

Speech recognition is a ground breaking technology and it will make Sugar Labs more captivating.It has a vital place in education and with time,it is making inroads as an assistive technology.It will have innumerable benefits to Sugarlabs Community  like -
 +
 
 +
> It will make the interface of Sugarlabs attractive and learning fun.And when we learn something with pleasure,we never forget it.Various  activities like Play and Say games can be made to gauge pronounciation skills of children.
 +
 
 +
> Its most relevant application will be for users who are unable to type due to a physical disability. Speech recognition is the only way for their thoughts to get into readable form other than dictation to someone else.  
 +
 
 +
> The barrier of language difference can also be removed with multiple language support and assistance of multiple dialects in the future.It will help bridge the learning gap between teachers and students located round the globe.
 +
 
 +
>  Besides the advantages speech recognition will have in  learning,it will also make using Sugarlabs easier and quick.Users can perform various tasks like switching between running activities just by saying certain keywords.

This could be due the fact that there is still a missing glue between the speech-recognition technologies and educational content developers. This project is about filling the gap –within the Sugar Learning Platform.

Woukd be great have speech control in Sugar, for interaction with users and as a assistive tool. --[[User:Godiard|Godiard]] ([[User talk:Godiard|talk]]) 17:57, 18 March 2014 (EDT)

I will update my [http://nowirise.tumblr.com/ blog] weekly on the progress I have made on the project. Moreover, I will try to do the same on mailing list and IRC to keep the mentor and community informed.

I read somewhere that Summer of Code is not about how much you know. It is about how quickly you can learn and how eager you are to contribute to your Open Source community. I really want to give my everything to successfully complete this project.
