Welcome to our site! Three PCB boards are available for this project, see parts list.

HM2007 Voice Recognition IC

Thanks for dropping by alselectro! The 8 bit data is passed through an octal latch IC 74HC Potentiometer Questions Started by norbss Yesterday at Next solder the 10 position headers on the display board and main circuit board.

You are commenting using your Facebook account. I found a couple of sources with a google search. Now mount and solder the 3.

I have been searching it, one of distributor in malaysia Troper electronicbut troper not available, troper had sold out and no IC stock at this moment.! Email required Address never made public. We continue in this manner until all the words are programmed. Voice recognition will always be as easy to fool as a tape recorder.


Notify me of new comments via email. It is not necessary to train all word spaces. We do this for the remaining word spaces. Meaning the voice that trained the circuit also uses it.

Let us test the board by connecting uc a Motor through a motor driver hm20077 L Circuit Construction The schematic is shown in figure 1.

First you are trading off word vocabulary number for speaker independence. However the circuit will require driver software needed for control training, storing and recognition. To train the system for speaker independent recognition Multi-user use the following technique. To find out more, including how to control cookies, see here: A 12v adapter can be used as a power source, as the board has inbuilt 5v regulator with heat sink.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Jc at It is used in Robotics to control motors according to voice commands. Next solder capacitors and voltage regulator. As the RAM is volatilea 3v button battery is used to backup stored data.

It responds almost to every voice in testing mode This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. This L can drive 2 motors at a time. This demo circuit allows you to experiment with dependent as well as independent systems. To stop the motor decimal 08 is assigned. Thread starter iamravikanth Start date Dec 26, This HM wasn’t designed for use in a voice security system.
