Hello,
······ well i am working on another biped robot now & i'm looking for help here on a voice recognition for basic stamp? does anyone know where i can get a plug & play board that i can connect to a basic stamp board? or the parts i will need to build a board my self & where i can get what i need to do this? if anyway can give me some help here that would be great.
······· this is my 3rd biped robot i am build & i want to add even more function to this one. i just got the roboeye vision system, the emic voice board,atom bot board,ssc-32 servo control,basic atom pro 28 pin module,ir proximity detector sensor,on-board battery checker,serial lcd module & 32 high torque servos. i want to add a voice recognition to the robot so it can follow voice commands. the robot stands just under 3 feet tall.i made the shell of the bot out of fiberglass in a form of a female being alot of the bots out there look more like male bots.also to help the person the bot is around to feel abit more comfortable.
if anyone can point me in the direction to get the voice recognition·system this would be a big help. once i get the bot done i will post some pix of it.

i am designing the robot help help people in assisted living, to pick up phone & hand it to the person, get them a drink, pick up things they may drop & get the mail. just the basic stuff right now that may be hard for some people that has a disability & may not be able to do it for them self. this is what i have planed for the robot. it's name is ( a.l.i.a.)·assisted . living . intelligent . android .

thanks to all for any help i can get.
Charlie

    I would look at Voice recognition as more of a toy, than a usable component. You should download some speech recognition demos and see how well they actually work. even on a PC with 100 times more processing power they are hit and miss. and that's in a quiet room. You add in the noise of a TV and you'll be lucky to get any commands right. If you are dead set on adding it to a robot I would recommend letting a PC do the speech recognition. have the pc send commands to your bot via a Blue tooth adapter. If your looking to have this bot do the things you listed by with people with disabilities. I think you'll need a level of accuracy that you just can't get at this level of technology. I'd love for you to prove me wrong, but I've played with Voice recognition for over 15 years. For what ever reason they just can't seem to get it right. Even Microsoft couldn't get the voice recognition to work on there release of Vista. The live demo failed miserably. sorry to be seem so negative. It's not my intent. good luck on your projects
    I did some searching and the only item I could find was from your same post on lynxmotion forum. the VR STamp

    I have a very old program intended for win 95, I think it was called Via - voice. (1990's)

    if you train the program many times, (even train it on noisy enviroment) I was about 82% accurate.

    the trick, is·training the same comand, over and over;·and in different·parts of the day. The human voice goes though changes during the day, specialy in the mornings.



    P.s.· I am building the arms for your viped, lets get it done...

    robonetics,
    There are several speech to text programs. ViaVoice is one that still exists for the PC and has been improved over the years. I use MacSpeech, obviously for the Macintosh, which also has the ability to control various programs. It comes with script packs complete with the tools to take specific phrases and use Apple's AppleScript to send menu selection and other commands to most common programs. If you had a Mac, you could make your own script pack with specific phrases that would cause commands to be sent to a Stamp or other processor via Bluetooth or an xBee serial channel.

    You have to speak slowly and clearly, but you can use continuous speech (you don't have to separate the words). You do have to train it for a given speaker by reading some sample text. The main problem is that there are still errors and you'd have to design the phrases so they are fairly unambiguous. You do need a fast, large memory PC or Mac at the very least. People have made standalone speech recognition systems, but they have very small vocabularies (maybe 12-15 words), they require discrete words, and they make lots of errors.

    have you ever looked at sensory inc's products. they are used in quite a bit of toys. i used the voice direct 364 on my robot strongbad. it worked really well. i built a carrier board for it and that was'nt hard at all. it's simple to use. not to bad of a price and has all kinds of little features built in. this may not be what your looking for, but it worked for me.

    i could say "Robot, Dance." and he would!

    but my favorite tweak was a party popper stuffed with alluminum foil bits, mounted in his back with the string wrapped around a servo. when i would say "Robot, Play dead!" he would pop and make noises and shutter to a halt. it was quite impressive! take a look here at the specs and check it out

    it's simple and doesnt require lots of processor or battery power.

    this would be good if you just used it to STOP or SLEEP might have to look into 1 how hard are these to hook up and program

    they are fairly easy to use. but i think it uses up to 8 i/o lines to work the recognition, and i think one more to use the built in vocabulary for speech synthesis... but i never used the voice part. the documentation can pretty much answer all your questions.

    Nice tip about the VR Stamp. At $39.95, it appears to be to smaller, lighter, and more mobile than using a PC with bluetooth.

    The dev kit seems a little pricey at $350.

    At $130, this Easy-VRStamp board (cost includes VR Stamp) seems a lot better.

    Do you have the board?

    The $350 dev kit includes two VR stamps, programmer and development software you definately need that the Easy=VRStamp board does not include.

    Go with the $350 dev kit for my money value!

    Hi

    I have used the Sensory VR Stamp on a Voice Recognition Dalek and it works great. I have put a video of it on Youtube: http://uk.youtube.com/watch?v=X7kygMHrYq8

    Just discovered the Propeller, what an amazing chip, will be using it in the new automonous half size Dalek that I am currently building.
