    Re: speech recognition IC HM 2007.............. help needed.....

    thats is the best IC for these kind of application.. Its costly but the best bet ... its around 3K.. you need to train the IC with your voice and it stores your voice.. you can get it from N S K E L E C T R O N I C S the cost of complete module is 4500Rs.

    I had designed my own circuit for it and gave it to NSK for production....

    I did around 20 projects with that without any problem

    you get IC for 2500 or 2800 Rs in NSK or sunrom... try it there..

    Re: speech recognition IC HM 2007.............. help needed.....

    hi ckshivaram,
    can u help me in voice recognition system project,
    i working on voice recognition system project, in that i using hm2007, i got reference from following pdf
    http://www.sunrom.com/files/1180-datasheet.pdf
    but in that i directly give 5v supply to sram ic, when circuit is turned ON ready led is lit & according to training procedure after pressing keypad key ready led should OFF & after pressing TRAIN key ready led ON OFF, but i am not getting this output, can u suggest is any changes required to get approprite output

    Re: speech recognition IC HM 2007.............. help needed.....

    hello! i see you posted this back in 2010. Well i have a question. If i dont buy a kit which is all over the internet and just buy a random HM2007 from the market and connect it as shown in the circuit diagram (PHOTO)will it work.
    what i mean is do all the HM2007 contain the voice recognition program pre-loaded to it?

    Hi,
    i also done same as u, basically the circuit work depends on their control signals(refere IC's datasheet)
    i not get desired result, still searching.

    i think HM200 voice regognition processor, u have to train HM2007 voice recognition IC to store ur voice cmd in SRAM chip

    thanks & regards

    so do u mean that i can buy HM2007 from any where and connect it as per the schematics and i will be able to train it using my voice?
    what i am confused about is that whether the IC available in the kit is programed by the sellers as part of the kit or any of those ics can be voice trained.

    Re: speech recognition IC HM 2007.............. help needed.....

    Hello Everyone,
    I was doing some research and noticed that the HM2007 speech recognition kit only recognizes isolated speech and not continuous speech. I would like the system I am planning to design to recognize a full sentence like asking "what is the time?" My design is basically an alarm clock that tells the user the current time, date and temperature when asked. Please what kind of IC or speech recognition kit can I use for this?

    Thanks in anticipation of your reply,
    Rapheal

    what is the difference between speaker dependent voice recognition circuit and speaker independent voice recognition circuit?

    Re: speech recognition IC HM 2007.............. help needed.....

    hello,
    i made voice recognition circuit using HM2007L, in that i connect
    TEST pin to GND,
    WLEN pin to VCC,
    CPUM pin to GND,
    WAIT pin to VCC,
    but after voice recognition circuit turning ON led connect to RDY pin is not glowing

    for HM2007L set in training mode TEST, WLEN, CPUM, WAIT pin connects to?
    for HM2007L set in voice recognition mode TEST, WLEN, CPUM, WAIT pin connects to?

    hello,
    i made the circuit mentioning in HM2007L ic's datasheet (CPU mode & manual mode), when i give supply (5v) to this circuit ready indicator led not glowing made setting as TEST -> GND, WLEN -> 5V, CPUM -> 5V, WAIT -> GND,
    how i can toubleshoot this circuit?
