Error Related to Linear predictive coding (LPC) for speech recognization in Labview

[Nirav_Virpara]

Hello,

                       i m make one program in labview for speech recognization in labview .   i make one wave file of word " forward "  and convert it into waveform data and  use Linear predictive coding (LPC) SubVI which available in NI site in voiceanalysis program to generate formant graph. i getting two error but i m not getting the mean of that error .. so anyone can tell me how to solve this type of error and what error want to tell. ?

please someone  help me ... i m very confuse .

i attach two file related to error ...

We would need to see the code to help, these error message snapshots aren't particularly useful - they seem to indicate your waveform is empty?

Thanks a lot to reply me ...

ya u r right sir .... waveform was emplty ... error solved ...

thanks a lot again to reply  me  ....  🙂 🙂

Hello ,

can u help me more  .... ???

I m make on program in which i use Linear predictive coding (LPC) method to extract feature .    first i genrate two wav files of same word  " forward " and  generate two waveform of that wav files . then i use LPC SUB VI OF  voice analysis program which available at ni site  ...   and generate formant graph and  intensity   graph ....   now i want to check that both word are same or not ...    now how i check that  ?? .... can anyone guide me  ??

please help me .....

You will need assistance from someone familliar with that set of tools, which unfortunately I am not. Without trying it myself, which I don't have time to do, I probably can't help any further.

If  i send u all vi related  to this topic then u can help me ????

[Nirav_Virpara]

anyone have any idea related to this topic .... ???

please help me ....

 anyone have any simple program related to speech recognization in labview ....  ???

How large would an example project that demonstrates your problem be? Can it be zipped up and attached to this thread?

[Nirav_Virpara]

i attach my labview program and paper which i refer for speech recognization  ...

if u understand the code and paper ...

then please tell me what is next procedure to compare two words are same or not ?

for that make two wav file of two words like " forward " and  " reverse "

This paper talks about Speaker Recognition, not Speech Recognition, they are two different things. One recognises a person by analysing the characteristics of the voice patterns, the other is about interpreting the spoken words of a person. You need to interpret the spoken word in order to compare two wave files for identical spoken content, which is not what this research work is about.
