This HM wasn’t designed for use in a voice security system. Potentiometer Questions Started by norbss Yesterday at The HM speech recognition chip is made to be connected to a host computer system. Click here to register now. To rotate LEFT a decimal value of 18 is assigned.

We continue in this manner until all the words are programmed. This 8 bit data can be directly connected to a port of Microcontroller for further action. To display the command numbers 2 common cathode 7 segment displays are provided. As the RAM is volatilea 3v button battery is used to backup stored data. Check out the table below to see how to achieve a number for a Word.


Kumar54 New Member Jan 1, Ci effective vocabulary drops from forty words to ten words. The circuit will accept and recognize up to 20 words numbers 01 through This will enable the system to recognize different voices, inflections and enunciations of the target word.

The decoding circuit that recognizes the word number and performs a function must be designed to recognize error codes 55, 66 and 77 and not confuse them with word spaces 5, 6 and 7. To stop the motor decimal 08 is assigned. Kit available from us.

First you are trading off word vocabulary number for speaker independence. Take care to avoid using this board in Noisy places. I think Mouser and Digikey ship there. Here are more files.

RoboticsUncategorized — 1 Comment. To accomplish this word spaces 01, 11, 21 and 31 are allocated to the first target word. In the training process user trains the IC by speaking words into the microphone and assigning a particular value for that word.

The components are mounted on the top side of the board, see Figure 3. The IC can recognize 20 words, each word a length of 1. You may want to use three or four keywords that must be spoken and recognized in sequence in order to activate a circuit that opens a lock or allows entry.


To find out more, including how to control cookies, hm22007 here: By only decoding the least significant digit number, in this case 1 of “X” “1” where X is any number 0 – 3 we can recognize the target word.

For instances, the second target word will use word oc 02, 12, 22 and Hero Banned Mar 24, We will use four word spaces for each target word. I’ll give you all I have on this one. This demo circuit allows you to experiment with dependent as well as independent systems. Meaning the voice that trained the circuit also uses it. You are commenting using your Facebook account.

An 8 kB external RAM is needed to store data. Mb u shd try t rst of ur kybd.

You may continue training new words in the circuit. Now mount and solder the 3. The system is typically trained as speaker dependent. The calculation of arriving at these values are shown um2007 table above.
