# '''''Writing a system service that will take speech as an input and generate corresponding keystrokes and then proceed as if the input was given through the keyboard.''''' (This method was suggested by Benjamin M. Schwartz as an simpler approach as compared to writing a speech library in Python which would use DBUS to connect the engine to the activities in which case changes have to be made to the existing activities to use the library.)

# '''''Starting with recognition of alphabets of a language rather than full-blown speech recognition.''''' This will give an achievable target for the summer of code. As the alphabet set is limited to a small number for most languages, this target will be feasible considering both computational power requirements and attainable efficiency.

# '''''Create acoustic models where the corpus is recorded by children and where the dictionary maps to the vocabulary of children to improve recognition.''''' (I have been working on creating acoustic models for Indian English and Hindi. This part needs active community participation to bring in support for more languages. The Qt application can come in handy for anyone who is interested in contributing.)

The above mentioned goals are very long term goals and some of those will need active participation from the community. I have already made progress with Steps 1 and 3 (which could go on concurrently).

'''I propose to implement steps 2, 3 and 4 in GSoC. As the basic speech engine is working, these steps can be treated as independent of the later steps and will have immediate benefits.''' i.e.

# Writing a system service.

# Writing a system service.

The speech service will be a daemon running in the background that can be activated to provide input to the Sugar Interface using speech. This daemon can be activated by the user and can be 'initiated' via a hotkey. This daemon will transfer the audio to Julius Speech Engine and will process its output to generate a stream of keystrokes and are passed as input method to other activities. Also the generated text data can be any Unicode character or text and will not be restricted to XKeyEvent data of X11 (helps in foreign languages).

Beyond this I would like to implement an activity that can quite well demonstrate the use of this service. I plan to Implement Speak Spell which will be a spelling activity where children can spell out the words show to them. Single character recognition can have very high recognition rates.
