  1. ALPHABET RECOGNITION USING SPHINX-4 BY TUSHAR PATEL

  2. 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?

  3. 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

  4. 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

  5. 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.

  6. 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

  7. 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.

  8. DEMO OF PROJECT

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

  10. 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.
