Hanno's speech recognition completed at last!!!

I have searched through my project notebook and saw Hanno's specs written down with all but "knows 6 words" and "fits in under 15k" marked off. I then got out Phil's goertzel speech program and started modifying the demo to meat the specifications. 2 hours later I have a functional object and I have finally gotten those last 2 things crossed off the list. Attached is the modifyed speech program and the goertzel object. I don't have a demo for the object written yet, but that will not be hard and I should get one up soon. I will admit that the "GetWordSamples" PUB is a disaster, and while a good consept will not work right yet. I am beginning work on that now and should have it done soon. BTW, special thanks to Phil for another wonderful speech related product. smile.gif

    Thanks! Haven't progressed on the demo yet, still revising/correcting my N&V article. I should have it up before the day's over, though!

    Congrats Microcontrolled!
    I'm very proud of you for sticking with this project. Controlling Propeller projects by speaking to them will be so cool!
    I've sent you a license of ViewPort Ultimate and will include your object in 12Blocks as soon as you're ready. (Congrats also to Phil for his work- he also won a license [noparse]:)[/noparse] )
    Time to get ready for the next challenge!

    Way to go Micro! Many people would have lost interest after this amount of time.

    Awesome Hanno! This will really help!
    @hover1: Thanks!

    Attached is the modified code. No demo yet, but it is on the way. I discovered on the old code that the "GetWordSamples" PUB was not working, but this one fixes that error.

    Good going, Micro! I'm glad you didn't let it fall through the cracks. If you ever go into business for yourself, you'll find that it's much easier to find customers for the things you finish than for the things you start. smile.gif

    I'm debugging it with ViewPort....... There is some wacky variables going on, but I'll get the bug out soon.

    Could someone post some links to the background behind all this, sounds really interesting.

    Also, my original speech recognition program is in the OBEX.

    ·I did not realize speech recognition was that involved. I had wondered when someone would create an object that·could decode·a stored bitmap of the programmer's face.·My inexperience shows.

    I Propeller could NOT do that! This speech recognition took months to complete. If you want a speech comparison (for security, as it only recognizes your voice) you can try my driver in the OBEX. It only took 4 hours to complete. Propeller.gif

    I've learned from experience not to say things like this...


    Why couldn't a Propeller be programmed to recognize a face? Heat sensor maybe?

    OK, I should have said that it would be HARD for a propeller to do that. It could surly recognize a face, but it couldn't process the video power to recognize 1 from another. Well, it could with the help of ViewPort. \
    Every time that you think the ol' Props not capable of something...... it is. I bet $10 BradC will be the first one running Linux on it. smile.gif

    A face would be no harder to recognize than a voice *and* you could do it without Viewport. It might take some time given the lack of on-board resources though. All you need* is a cam that propeller can read, an sdcard, code to encode/decode face "attributes", and code to find attribute matches.

    I'm still waiting for the voice recognition demo video [noparse]:)[/noparse]

    *Note: famous last words.

    What is the name of it? I would like to study it. I'm a beginner and I was just listening in. I thought the prop could decode the pixels in a bitmap

    Wow! That's very impressive, micro! A couple of years ago during my sophomore year(BS electrical engineering), I had a course project where we had to write a program in Matlab that would recognize spoken digits, 0 through 9. My group got about 70% accuracy - the 2nd highest in the class. Granted, we started off by not knowing anything at all about speech recognition, but by the end, we learned an incredible amount. Now that I've taken the more advanced subjects like Linear Systems, and discrete signal processing, I have a better understanding of what we were doing back then... However, going through something like this and disecting it on your own is an invaluable activity. I can't tell you how many clumps of hair I pulled out during that project, but it was totally worth it in the end. I'm sure you've learned a good bit just from doing so much of this on your own. Way to go, and keep it up!
