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.

[...] Awesome news! The Montreal Gazette recently published a nice article about the international cooperation project I participated some time ago: The Ecuadorian Makecation. [...]

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

@Camille Wow! Thank you for that very kind comment. I am really really happy to see I could inspire someone into building things. I'll be glad to answer any questions you or your son might have for your creations.

Hi Carlos. I am a mother of 2 young boys. Andrew is 9 and is now a fan of yours! He loves Iron Man and tech-y stuff so your video gave him great hope for his future engineering endeavors! Within 5 minutes of his seeing your video on the repulsor, he ran through the house looking for old cameras and computer and electrical gadgets to begin “building” his own! Ha!
Thanks for using your God-given abilities to use and igniting a passion for the same in a young boy!
Blessings to you.

@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!

Mr.carlos plzzzzzz can you give me just the code of block that compute the distance I’m really need it very much. please sir send me only that.
Here is my email if you want to send it to me. style2006_b@hotmail.com
sorry for such questions and thank you for your help.
best regards.

@jesska Sorry for the delay. This is quite simple: let us say a word (an actual sound) lasts for 1.024 seconds, and that the sound is sampled at 5 KHz (5 thousands times per second). This means that for a 1.024s sound there will be roughly 5000 samples. So, in order to compute the FFT on the sample we need a roughly 5000 points FFT, or five 1024-points FFTs. I hope this is clearer.
