    Well. You must not need a super computer for that to work. The autopc (310c, the first model) had a 66mhz hitachi processor.

    Yes, there are two winamp plugins that i know about. Trimodal and VoodooVoice. Sadly, i have lost the URLs to both, and considering i helped write one, that is a pretty big feat. E-mail me if you really want them, and i can spend some time digging out the source code and recompiling it.

    Cool

    Just so you guys know, voice control can (and has!) been done. Voice control isnt rocket science, and Microsoft's newest SDK's make it even easier. (I know, I know, I hate Microsoft too, but what can I say, it was the best/easiest thing out when I was writing my plugin (see above post from smashr).

    "Voice recognition, involve tons of cpu power. Imagine for a minute you have a song playing, it will pick up that sound and tries to process it, mind you this might go on for a long time, thus your command WILL never get processed. "

    That is not true at all. On my 800Mhz (which maybe used to be top of the line, not so much anymore) - I saw the response of voice commands almost instantly, with >90% accuracy. In a car I had maybe 80-85% accuracy, with a 1-2 second latency on the commands, not bad when you think about it.

    In case you don't believe me, I will rant some more. For those of you who are convinced, you can just stop reading here. (Oh and by the way Charles Enwesi, what exactly is "Day 1"?)

    First of all, any decent programmer will think of a solution to background noise (i.e. music). My straightforward (perhaps not the best) solution was to turn down the volume of playback automatically when a command is recognized. And no, it doesnt turn down its volume every other second everytime somebody says something. It only turns down the volume on recieving a wake up command (which can be set by the user). Ideally this command should be something that is easy to say and recognize, yet not something said frequently in every day conversation. (I have found "Computer" to work fairly well...). Upon recieving the command, the plugin turns the volume back up.

    Second, the speed/quality of the computer SHOULD NOT be an issue. Smashr (see above) had a plugin called VoodooVoice running on his K6-2 400Mhz laptop (64MB RAM) a long time ago with around 85% accuracy. We had my plugin running on a BookPC, as well as our "CoolPC" (a substition we built to the BookPC, which didnt work right). I mean heck, you cant hardly buy a decent computer under 800 or so Mhz any more! And if your building your own, a K6-2 450 is only $25 dollars on pricewatch.com!

    Third, the issue of a microphone shouldnt really be an issue at all. With a $10 headset microphone I bought at Radioshack (the headset part cut off, leaving just the microphone), I achieved almost maximum accuracy from over 10 feet away (the same results as someone earlier on this post ...) In a car, this microphone can be mounted on the sun visor thingie, and thus is only a foot or two from the speakers mouth, and out of the way.

    Basically Ive lost my train of thought, but for anyone that still thinks voice control doesnt work in a car, email me at [email protected] and I will provide a longer, more in depth review showing how and why it works (if I can find the report me and smashr and mellman wrote ....)

    Something really kinda unrelated, but in response to a post by JamesB. I agree totally with him

    ".. in case anybody needs more background on the conecpt .. it is similar to the concept of harmonic wave cancellation .. as a point of interest, 8 or so years ago, I saw a program on TV that showed a car running yet producing almost NO sound (WIHTOUT a muffler!!) .. this was done by sampling the engine noise and reproducing and exact copy at 180' out of phase .. thus cancelling the sound that the car made (almost completely) .. cool huh ? "

    He is completely right about that. At work I am working on a few projects that involve that technique, we have a speaker generating noise, a microphone sampling that noise, a layer with a control speaker attached, and a microphone monitering the noise on the other side. By cancelling the noise signal with the control using an FIR filter, we achieved really great results! (The noise was almost zero at the performance measuring microphone)

    Thats my 2 bits

    If the moderater happens to come by here, i doubt if you guys keep the logs. but check back a few months ago, like february-april time, and look for the big voice recognition thread, it'd be helpful if you could send it to me or just repost it for these guys. thanks! and you guys who think its not possible....yea....*laughs* anyways, email kevmo for the program.....and it works great. well happy voicing!

    I would just like to say, I am 100% willing to let people use my plugin/modify the source code (if they wish), as soon as I find it. Email me if you want the .dll or the source ...

    Unfortunately, I recently reformatted, and I am still looking for the CD I put my code onto ...

    I LOVE YOU GUYS! Whoooooo I finally have some back up. I've been beaten up too many time from the anti-vr clan before and I'm so happy someone sees through the smoke.

    Talking

    Aaaah i just love it when the gang jumps in. Its not that i dont think this is not possible, its just that i dont think today technology is really ready for VR in the car. I want you all to answer me this. Where are your setups to prove this?????. Also Do you really think for a minute that the average carpc out there have enough CPU to do this crunching? Kevmo, 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. 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. 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.

    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.

    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 =)

    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.

    ok lastly(i htink) Who ever said anything about the average joe having mp3 in his computer anyways? the most average joes i know are like "Mp3 what?" and anyone who wants to put mp3's in their car, without 'viable' commercial option on the market isn't the average joe. so i think that the 'average joe' as you call him may in fact be you, the person who doesnt know what they are talking about. wiring it into the car, how hard could that be, you need power, and maybe a visual for LCD, which takes wiring in the first place, so just running wires in your car for it is a piece of cake. and then what else, sound, thats real hard get a male to male adaptor or hell use a casset adapter to hook the baby up to your car, and plugin the microphone and start her up and your ready to go. i dont think car stereo's install that easily. it may not be pretty but if you put some work into it you can make it look professional.

    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")

    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....


    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.

    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.

    to get the software, listen in here and we'll post the site whenever we find it

    a side note to kevmo i may have the finals of a few of them around here somewhere i've gotta look through all my stuff though


    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

    Didn't mean to be so harsh, but ignorance annoys me
