iPhone support Voice recog?

nick5454 · 01-29-2009, 05:52 PM

I have no idea where to get a list of hardware capabilities for the iPhone

But can the iPhone handle Speech and Voice recognition?

Links and answers is appreciated.

Thanks,
Nick

Oh yeah can the iMac also? Mine doesn't arrive til Tuesday so I don't know yet. Can't wait.

And does the simulator accept voice recog if the iPhone does?

Thanks!

the google mobile app has working voice recog, so the answer to your question is yes, the recording audio quality is good enough.

as far as actually recognizing the audio, you aren't going to get any help with that on this forum...

I think google does it on the server. They send the recorded sound to their server and he recognizes it.

There is no hardware supported voice recognition. Not on the iMac nor on the iPhone. You can build your own but the iPhone has "only" a 500 MHz ARM processor... so not much processing power.

I believe that Google's service is probably doing something similar to Shazam, and sending either a small token or three generated from the audio locally on the iPhone, or a heavily compressed audio stream (like mono 32Kbps or something awful). If they didn't it would be painfull slow to upload decent recorded quality PCM of your voice from an iPhone to a server for parsing.

So it's not a question of whether its possible, but if google has a web service to utilize.

Voice-Recognition Search from Google coming to iPhone | iPhoneIndiaBlog.com

From my reading it says that Mac does have this ability. Whether thats true I have no idea.

But, since google is using thier server to relay the data collected, then it's much easier to use Microsoft tools.

Unless google offers a free web service to use.

I'm sure the quality will be lacking tho.

You could theoretically do it in your App itself; but you'd have to write mathematics functions to analyze the incoming waveforms (FFT analysis). This is not easy...unless you are a heavy hitting dev company or are a math genius I doubt you'll get very far; though I suppose you might be able to swing something "simple" like only having two states of recognition ("yes" type or "no" type).

i recommend researching into open source Voice-Recognition software for linux.

Then on the iphone, just record the sound and upload to the server for analysis and reply back with the command.

Well I've worked on IVR's for windows which is easier. Apple has a huge clause for Apps that contain anything from Open Source.

Yea, that's why the open source voice recog. should be done on the server side.

The iphone app with just receive commands from the server.

sorry i haven't done any work on actual voice recog. a google search shows up a few from universities like CMU
