Voice Recognition ....

[koolguy]

Hi,

I found this chip for Voice Recognition Hm2007 then buy expensive V.R. module..
have any one used it before..?for any projects?

 

[misterT]

Well, the datasheet says "An intellengent recognition system can be built." ... I think the word "intellengent" says it all.

What is the use of keypad and 7 segment display in data sheet ckt...

 

[misterT]

The keypad is used to teach the device. You enter the word number that you want to record (or erase). I think there are two second memories for 40 different words you can teach to the device.

OK, After that storage when someone will speak it will work for individual or everyone??

I have no idea.. even if they advertise something, I do not believe it.. Has anyone ever used voice recognition that worked? Has anyone ever wanted to use voice recognition? Voice recognition is useless.

Voice recognition is useless.

Why??For making Robot its nice..
This module is costly but i think its fine..

Well yes, it may be fun to play with..

Well yes, it may be fun to play with..

why u said its useless?

So you can tell the chip what to do LOL.

Well, have you ever used a system with voice recognition and thought "this is great!".. no. Nobody has.

I bought my daughter a voice activated diary one Christmas.... Once locked we couldn't open it.. Suffice to say it went straight in the bin...

Was it a "Girl Tech" one like this ? **broken link removed**

I bought my daughter one as well for Christmas and we had great fun pretending to be her to get it open ...

 

[Ian Rogers]

Yep that's the one..... She recorded the password when the radio was on!!!! Try and open it then!!!

Yep it's like paying a bill on the phone. "I didn't get that can we try agin." nope for the last time put a real person on the phone plz LOL

Since we seem to be a little OT, let me add a quick answer.

Yes, higher end voice recognition systems work and are great. In my profession, they cut transcription time, reduced cost, and improved our service turn-around time. Moreover, there was minimal training for each of the >10 people using it.

But, our system did not need to understand the words. Hence, our bad experiences with such so-called "intelligent' systems at the power company are probably universal.

Once again.. use your money to buy PicKit. It has a logic analyzer, so you can debug all the I2C stuff you are struggling with. Don't waste your money on this voice recognition chip.

yep that would be a good start

As ALWAYS, I am late in replying to a thread. If this helps.

I have had two colleagues use the chip but it hasn't performed satisfactorily (as should be expected). I know, voice recognition technology is getting better (SIRI) but I assure you that the HM2007 does not do that. It does recognise words but not always. If you are building a robot, I suggest you also look for a computer aided system in which you perform the recognition as backup.
