<br>Hello everyone, <br><br>Here is the status update of GSoC speech recognition project for open moko. I have implemented some subroutines in C for the implementation of Hidden Markov Model for speech processing. As ARM 32-bit processors do not have inbuilt fixed point arithmetic, So all floating point calculations are emulated in software. As a result the processing time is very high and performance degrades dramatically specially for multi threaded applications. So, I have written fixed point codes in which all calculations are handled through fixed point. I have used the 16:16 notation for fixed point and used 32 bit integer to represent a fixed point. Multiplication and division procedures for fixed point are implemented through macros. As the project progresses, the stress will be given to optimize the codes <br>
more.<br><br>Currently the coding phase of this project is going on and some codes(without full compilation) have been released here: <a href="https://projects.openmoko.org/frs/?group_id=146" target="_blank">https://projects.openmoko.org/frs/?group_id=146</a><br>
(I couldn't use the svn because my public key is still not authorized). <br><br>An initial Design Document for this project has also been released and can be found here:<br><a href="https://projects.openmoko.org/docman/index.php?group_id=146&selected_doc_group_id=145&language_id=1" target="_blank">https://projects.openmoko.org/docman/index.php?group_id=146&selected_doc_group_id=145&language_id=1</a><br>
<br>The coding phase will continue for some more time and after enough amount of code is ready, I will start working on open moko tools and start building test applications to get comfortable with it.<br><br>Any suggestions and comments will be highly appreciated.<br>
