Thread: voice recognition (sp?)

If you think about it, how well would voice recognition work while music is playing? You would have to shout over the music which would increse the inacurracy of the recognition, and the music in the background would interfear also. That is, unless you wear a headset mic while driving

Adam F said it better. I have said this from DAY one(1) it just WONT work, i dont care what other ppl tell u. Really think about it, you have music going on in the bacground, not to mention outside noise + engine noise....
Even if you do get it to work, you might need to cut off the sound/mp3 then issue the command. Now here is another thing ppl dont think about...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. I can go on and on, but let me be quite.... Take it from me, i dont think todays technology is ready for voice yet, it is a totally diff ball game especially in our case.

actually.. i've gotten the voice recognition to work, while being 10 feet away, sure i have to raise my voice a little it'll follow my command, and this was while the music was cranked up on my home pc.

i mean.. i don't want to sound like a concietied newbie... but yeah

lol...go try it in the car and come tell me what happens. Doing it at home and doing it in the car are two diff things.

true that...


i'll have to see...

Grrrr...I'm sorry, but this topic fires me up when people say it' WON'T WORK. Because I HAVE DONE IT..with an extremely high success rate. Near 95%. Despite the theory of extensive background noice interferance. I have had it work with music at normal levels. It worked great. If you don't believe me go to your local car stereo shop and test out a Clarion AutoPC.

Clarion AutoPC != BookPC (or any other computer, for that matter)

the autoPC is very specialized. The software out there for consumers is NOT what is in that. the AutoPC may work, and individuals may have varying results with voice, but no one should blanket generalize it as good or bad

The Clarion AutoPC, or now what is known as the "Joyride", uses Windows CE. I'm not blanketing and saying that every type of application people attempt at VR will work, but you people often make it sound like it is an impossible task.

If you ask me, ANYTHING is possible, depending on how hard you try and how bad you want it. Getting VR to work is not a miraculous feat, and can easily be done sucessfully. All this huff and puff about background noise is hypothetical, I've not seen anyone actually try this and not have success.

About the comment about having varying success rates with the autopc; Let me just note that I've installed it in three different cars. A '94 Ford Probe GT, a '97 Audi a4, and my current Acura Integra. I recently sold the autopc and the buyer also claims to have great results. So it doesn't vary incredibly, if you install by manufactures suggestions.

Please also make it aware that I am not out to bash anyone or flame. I just get upset when people are so discouraging. Especially with the fact that many who do have probably not even tried such a thing. So I appologize if I come off as [add synonym for extremely rude person]. Thanks.

OK, those who say voice rec. will not/never work need to read up on how such software works.

The quick and dirty is that voice recognition CAN and WILL work over music is due to the processing of the voice input. With better (more advanced) voice recognition software (and hardware for that matter) you are able to specify (and in some cases select) a noise floor .. this covers sounds that will be constant under operating parameters .. ie. if you have an industrial fan running near your mic. when you specify the noise floor, the software(hardware) will "ignore" the sound(s) created by the background elements [in this case, the fan] .. this is noise floor cancellation.

To further this concept, with tweaking, you can specify a "live" source for the noise-floor .. that is: you can specify a WAV or AUX / line source as the noise floor. Application: you specify the WAV portion of your sound card. This will instruct the voice recognition process to ignore ALL (a defined tolerance) input that matches the "live" sound floor. Ie. When you specify the WAV source, the voice recognition will ignore all sounds that match the music / whatever that is being played .. it will ignore all similar tones to whatever degree you specify.

.. do note however that this technology is still very young .. but is however avaliable!

.. 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 ? .. I think many of us would benefit from a collar type application for our women =) [ j/k ]
