    </STRONG>

    Charles, you had to know what you were walking into here ..

    My carPC setup used a P3-700 w/ 128 MB Ram (laptop) .. and it has FAR MORE than enough gusto to handle VR with a > 1 sec delay .. futthermore, the accuracy is < 90 %

    Do remember, processor power has far out-evolved programming technique .. and as programmers are either forced or willingly program poorer each year, processors are being pushed to keep up ... so just imagine what you get when you actually code a GOOD program !!

    Bottom line .. when properly done .. there is only moderate CPU load at most .. which a P2-350 could handle ..

    <STRONG>
    Now there was talk about canceling noise such as car engine, etc,etc...let me think about this for a minute. So when i install this software, i will spend almost 1 day figuring what type of noise i want cancelled or what not. And whats this about having to issue a wake up command or what not. I seriously hope this is not what u guys are saying, cuz your average joe user out there that ventures into this carputer stuff have enough deficulty trying to figure out how to wire the carputer to their car non the less install an OS.
    </STRONG>

    Please recall that I mentioned the "noise floor" being all ambient harmonic noise (not electrical noise) .. this would be picked up by the same mic. as the VR mic. .. this would eliminate the need for any wiring (not that I can find a reason for the wiring) .. furthermore .. on the point of wiring: how many consumers do you know of who install their own alarm systems, or remote starters? .. if there were complex wiring to be done, obviously the market would rely on install shops.

    <STRONG>
    Until someone comes out or maybe one of u really do a demo to prove this to me, i will believe it and believe me i will have some question for you. If VR has really improved, from the last time i tried it, then i am in for it, i too have plans for VR, but i just dont think we are ready for it.</STRONG>
    Wow .. so I suppose you agreed with Bill Gates when he said 64k would be more memory than would ever be used? Be forweard thinking .. we have been ready for VR for the last 20 years ..

    In summation, the intent of my replies were merely to illustrate the technical possibility for VR in adverse conditions. Try not to take this reply as a personal attack, I merely want you to understand that there are people who _ARE_ working on VR systems with near 100% accuracy with 0 latency ... it WILL be commonplace within the next 5 years.

    Melmann, you're criticism of Chuck ( ) would have been much more credible if you'd taken a second to realise he's a moderator here, the author of Cobra, and not at all "New to the scene".

    However, he can be a wee bit defensive and discouraging. And I don't know what his obsession is with making things for average joes.

    lol....I think i have started a War here. this is going to be good.

    First off mellman99,
    ok charles, in case you cant read, THEY ARE IN OUR CARS. it works great. I have a 500Mhz k6-2, not what i'd call a superpowerful computer, and dont tell me you cant afford it, if you can't, you shouldn't be building a car mp3 player in the first place.
    Ummm i dont see NO PROOF and afford?? Do you know what i have??? I guess not.

    and engine noise, do you have some sort of 60's hot rod with dual quad holleys and open exhaust? i seriously doubt it, but if you do, bring it to me i'll fix it for you =)
    Oviously you have no clue what i have or what is done to the car. I seriously doubt i can even fix my car so lets not go there.

    what does it take for you to get it through that thick skull of yours THAT IT WORKS!!!!!!!!!!!!!! would you like to fly out here and see the damn thing yourself? i don't know how else to explain it to you. you must be fairly new to the whole mp3 car scene because there are plenty of voicers out there, back when we(mainly kevmo) were developing the voice software, a lot of other guys tried it and it worked, and well, thats all there is to it. it worked done and done.
    Once again, inorder for u to really convince me, i need proof. Why would i want to fly and there and see it, If you cant make a simple film demonstrating it, then shame on you. Wooo i can believe you went there, me fairly new to this ****. I think you might want to rethink that. Really, you expect me to believe that again?? there are plenty of voicers out there??? Get real dude.

    and installing the OS? good god do oyu live in like africa with 80-80's???? i mean i dont know about anyone else, but installing windows isnt exactly the hardest thing to do in the world. and if you don't know linux, or arn't willing to learn it, don't bother with it. (oh and by the way, what is "todays technology")
    Once again, you really dont know me and i dont know u. Who said anything about me installing OS. Do i look like a newbie to you. BTW stupid, ask MS what "todays technology" is.

    as for configuring it, and setting the wake up command, it's already set at computer, if you want to change it, then you just open up the source code, and find the location in the code where the wakeup command is, and change it, damn that was almost as hard as installing windows....
    Once again, good luck trying to get the users to change your code. Need i go more into this...


    i'm also curious as to what the average carpc is. with prices the way they are these days i'm sure almost everyones considering an upgrade, and if theyre just starting t here most likely not going to use their old junker p120s. so lets say average is a k62 300, yes, it works fine on it, sure accuracy MAY suffer a little, just speak clearer. or you can just have it be a slower response to your voice and be more accurate.
    You just said it....Ppl are NOT willing to shell out cas for high powered PC ok, maybe you and I can afford it, but not the once i have come across. And you expect VR to work....get real dude.

    AHH, i think i've found your main problem Charles, your interpretation of what VR is today. you've been watchin the jetsons too much or something because although true VRC is not here yet, its gonna be here soon. already in houses you can do many tasks just with the simple voice commmand, (yes, you can, i watch TLC and Discovery, its actually very cool) "todays technology" as you put it, is much simpler, and not as able to adapt to new things. basically, you hvae to tell it what to listen for, and then tell it what to do when it hears those certain words. but yea basically it works like that, ask kevmo if u want the actualities of it all.
    Lol you are just too funny...."although true VRC is not here yet" what is this you say... Bingo it is inhouse, when u take it out there to the real world, it will FAIL!!! get it through that thick skull of urs.

    ok to wrap this all up, Charles, you need to crawl out from underneath the rock you've been living under....and open up your eyes, i consider k6-2 500's to be pretty fast, 1.1 Ghz Tbird, yes, but they are fast enough for voice....so lighten up, and open your eyes
    Dude you really need to crawl out from underneath the rock you've been living under and open ur eyes, and just like you said, "although true VRC is not here yet" it is NOT here yet so stop wasting your time.

    Just so you know and i will resist myself from calling names or what not, but if u push, i will..... I took some hardcore computer classes dealing with this issues...and do you want me to list some other CS classes aswell

    P.S. I didn't mean to be so harsh, but ignorance like yours annoys me....

    Cool

    Ouch ... a little harsh

    Although there currently is no _TRUE_ VR (we still lack a good working definition of TRUE) .. we have software emulation that today competes with the DSP hardware of tomorrow .. as the two are eventually married into one design, we will see leaps and bounds of progress .. for example .. a universal VR module (ie. no training)

    Let's face it folks .. you still have to train your VR software .. and those of us who have done so extensively know just how much of a pain in the *** it is! (Who really wants to read war and peace aloud to a computer anyways?)

    None the less .. the scope of this messae has begun to wander a little ..

    A plea to all who read this .. let's not get on eachothers nerves .. people have made comments in the past without an extensive knowledge of the material .. so what ?? We don't need to pounce on their errors .. perhaps we might try to elaborate on the subjects that we are experts in (instead of staring these intellectual bashings)

    And in case it isn't already obvious, I have the pleasure of having been on an engineering design team that developed a new VR technology using ASIC technology married with some pretty sophisticated DSP hardware / software handling.

    Uhm, voice recognition is voice recognition, whether it's software or hardware, whether it requires training or doesnt' require any ever.

    Nowhere in the definition of voice recognition are any stipulation made as to it having to be done in hardware.

    As for whether or not Charles Enwesi can be convinced... who really cares?! If he wants to pretend it can't be done, then let him think that! It's only him that loses out.

    Meanwhile, his lack of belief doesn't stop it from working for those of you who use it.

    Lack of belief didn't stop the world from being round, either.

    Thanks for all of the help

    i also found a (the?) voodoo voice website:

    Ok I've been gone a while (ugh, work!) and I havnet had time to read all the posts above, but I skimmed. If I misread something, You will have to excuse me.

    From Charles:
    Ummm i dont see NO PROOF and afford?? Do you know what i have??? I guess not.
    How bout 1st prize in the regional science fair and 3rd in the state for our voice controlled mp3 player .... or the pending patent on it .... I hope you will take my word and not make me fax you the certificates or anything ...

    Once again, good luck trying to get the users to change your code. Need i go more into this...
    I thought I said my code wasnt ready for distribution, although I might have forgotten. It is a matter of adding a dialog window to be able to have the commands changed runtime - I was just lazy. You can change them in VoodooVoice

    , true MS since day one has been pushing for VR and i am sure as you know with MS, you WILL need one hell of a cpu + DSP card to do this job perfectly.
    Perfectly, yes. 90-95% accuracy, no. I dont even know what a DSP card is. I just stuck the software on a run-of-the-mill computer.

    Now I have to go to cross country. Again, Im willing to argue my point more because I HAVE DONE IT.

    I don't feel like ranting much more, but oh well. This should be quick. I have read many mentions of "true voice recognition." Now, even though that is hard to define, I never made any mention of "true voice recognition." I acknowledge that at least my program isnt "true VR." It is merely voice ACTIVATED. It matches outputs from the VR algorithm (neural net, vertebrae search, etc) to pre-specified phrases, and chooses the phrase that matches best to be "active." (or no phrase at all). This achieves the functionality of controlling MP3's, if the programmer is creative. If you don't understand, I will try to elaborate.

    In reply to the amount of power needed for VR - Did I mention that the AutoPC used a 66mhz processor? I hate to sound like a sales rep for Clarion, but just think of how much power they used in their application. The last time I checked we have processors reaching 1.7Ghz and above. Not that we'd put these systems in a car, I just felt like showing the radical gap.
