@shawnmk123 : Thank you. I just started with the basics of speech recognition. I'm reading . Sadaoki Furui, Digital Speech Processing, Synthesis and Recognition, Second Edition and Daniel Jurafsky & James H. Martin, Speech and Language Processing: An introduction to natural language processing, computational linguistics, and speech recognition. But I'm stuck on where to kick start. I'm new to LABVIEW but good with PIC. So, what i really need to know is the LABVIEW portion.
