Real time implementation of HMM speech recognition for telecommunications applications
Michael John Flaherty, T. Sidney · 2002
This paper describes an implementation of connected word recognition using commercially available parallel processing DSPs. The recognition system uses continuous density HMMs for speaker independent recognition over a public switched network. It describes how the computationally intensive functions can be optimised for efficient real time implementation. Results of recognition accuracy are presented for a difficult task of connected digit recognition with data from a live operator environment and an isolated digit recognition task.>
