Hi everyone. I am working on voice recognition sistem on TMS320LF2407 DSP. I have implemented a Baum-Welch Algorithm using papers: Rabiner, L., �Tutorial on HMMs and Selected Application in Speech Recognition� and Trebbe, H., �Correction of Errata in Rabiner�s Tutorial on HMM� as references and I still have a problem with scaling. I wrote code for DSP in Code Composer Studio and in C for PC. PC version is working but same code dont work on DSP. Some probability values in observation matrix appear to be larger than one. That is probably because underflow or overflow but I don't know what to do more. This message was sent using the Comp.DSP web interface on www.DSPRelated.com
