OUT LINE
• WHY SPHINX-4?• WHAT IS SPHINX -4 ? • FRAME WORK IN SPHINX-4.• PROJECT DEMO. • CHANGES IN DEMO TO MAKE MY
PROJECT.• WHY IT IS OPEN SOURCE FRAME
WORK?

WHY SPHINX-4?• The traditional approach of speech
recognition system design which is optimized a particular methodology.
• In Past, researcher need to develop whole system for only one simple change in research.
• Single approach• License requirement agreement• Sphinx-4 -Open source of frame work

SPHINX-4
• Sphinx-4 is a modular and pluggable framework that uses design patterns from existing systems, with sufficient flexibility to support emerging areas of research interest.
• Modular: - It Includes separable components of specific tasks.
• Pluggable: - You can easily replace modules at run time

FRAME WORK IN SPHINX-4• Front end: -Takes one or more input signals
and parameterizes them into a sequence of Features.
• Decoder: -Translate any type of language model from pronunciation information from the dictionary and structural information from one or more sets of Acoustic Models, into a Search-Graph.
• Decoder takes input from the front-end and search graph from the linguist for decoding and generate results.

FRAME WORK
• Linguist: -It is used to generate a search-Graph which is useful for decoder for search as well as hiding the complexities generated at the time of generation of graph.
• Language model• Dictionary• Acoustic model

ALPHABET RECOGNITION
• This is a project in which I used the open source frame work of sphinx-4.
• By making some changes in the given demo file, I have created my own project of Alphabet Recognition.
• The recognizer is alphabet-recognizer and recognizes alphabets.

CHANGES IN DEMO FILE
• JAVA FILE• GRAMMER FILE• CONFIGURATION FILE

HOW YOU CAN CREAT YOUR OWN PROJECT?
• It is easier to create your project by using open source of frame work of sphinx-4.
• Linguist Frame: - By allowing different implementations of the Linguist to be plugged in at run time, Sphinx-4 also allows individuals to provide different configurations for different system and recognition requirements.
