Hi,
Your project is good.But I didn’t understand the need of using FFT. Why was FFT used?
Can’t we recognize speech without using FFT? What will be the effect of not using FFT?

@Thiru I suggest you make sure you understand the algorithm in general. then, the implementation should be straight forward. It is very important to understand all the basic concepts before you worry about the details of the algorithm.

hai,sir
i’m from india..i already posted a comment..but i didn’t mentioned clearly about my doubts.

i can understand the matlab programs..and i gave one wave file as input & i got the output as distance 0,word is recognized!…

could u please guide me…wat can i do next sir…then after this i have to move to Quartus ii or else here itself steps are there sir…

then sir with the help your documents…i sucessfully created Block design files for memory controller,distance module and mux….

so please guide sir…wat are all steps i can do next…for your Kind Attention my

hi carlitos,
I read your project….i like it…and myself i want do the same as my final year project…

i can understand the matlab codes…i ‘m new to Matlab and Quartus II …

could u explain the steps from Matlab to QuartusII…

@vasun Speech recognition performed in hardware is different from the software counterpart in the sense that it can be integrated in a single chip and work without a computer. Also, this project aim was mainly combine various disciplines learned in the electrical engineering curriculum in a single capstone project.

hi carlos,
speech recognition already present in operating sysems like vista.what is the importance of this project.because it hardware cost more.please clear my doubt……..
i also done vhdl code for this project.please reply……

Hi carlos,
the sound length is exactly 1.024 sec or grater than that for input to training phase of speech recognition using matlab.i gave the input using microphone of wavelength 9 sec.after running the program it gives the error INDEX EXCEEDS MATRIX DlMENSION.

hi carlos,
I read your report of your project on speech recognition.
I would like if possible for me to understand the working principle of inputs / outputs of the block Memory Batch operator, and especially “start_addr”, “end_addr” and “done”.
thank you.

@Rushil The recognition is only accurate with the same user saying the same word in the same situation.

@Rushil The threshold must be calibrated to your particular setup.

Hi,
Considery that one person trains the kit.So, FFT values of his speech will be stored in training mode.Now if during recognition speaker is a different person, then what will be the accuracy of recognition?

Hi,
I have read your project, it is good.I just wanted to know that threshold value remains 0.05 only when you implemented it in fpga or it changes.

I Just want the brief idea about the performance of speech recognition process using VHDL implementation.

Hello Carlos,
Wats the major advantage in processing Speech in FPGA rather DSP ?
Which compiler u gonna implement here in your project?

@jesska Don't be sorry. BTW, I will gladly answer any specific question you may have. Of course this applies to all my readers.

@jesska As I said before: I do not have the code any more. It is in some obscure backup who knows where (that's how organized I am). And also, I'm sure you can do it yourself. It is a simple mathematical formula (euclidean distance). Good Luck!
