Model based neuro-fuzzy ASR on Texas processor
This is an incremental improvement for speech command execution systems, with implementation on a specific DSP hardware.
The authors tackled speech recognition by proposing an algorithm that uses MFCC features with MLP and fuzzy inference classifiers, achieving high gain and efficiency as demonstrated on a 600 MHz Texas Instruments DSP.
In this paper an algorithm for recognizing speech has been proposed. The recognized speech is used to execute related commands which use the MFCC and two kind of classifiers, first one uses MLP and second one uses fuzzy inference system as a classifier. The experimental results demonstrate the high gain and efficiency of the proposed algorithm. We have implemented this system based on graphical design and tested on a fix point digital signal processor (DSP) of 600 MHz, with reference DM6437-EVM of Texas instrument.
