Voice Recognition Module - VRbot

Replacement:COM-10685. The new version of this board has some added features. This page is for reference only.

The VRBot module is designed to easily add versatile voice command functionality to your project. This module provides voice recognition functions for built-in Speaker Independent (SI) commands and up to 32 user-defined commands (Speaker Dependent (SD) trigger or commands, Voice passwords (SV)).

A simple and robust serial protocol (9600 8-N-1 default) can be used to access these functions from the user's microcontroller boards. The VRBot can be powered by anywhere between 3.3 and 5.5V, and typically consumes 12mA of current in operation.

VRBot being used with the Arduino based POP-BOT.

  • A host of built-in speaker independent (SI) commands (available in US English, German, Italian and Japanese) for ready to run basic controls.
  • Supports up to 32 user-defined Speaker Dependent (SD) triggers or commands (any language) as well as Voice Passwords.
  • Easy-to-use and simple Graphical User Interface to program Voice Commands to your robot.
  • Languages currently supported for SI commands: English U.S., Italian, Japanese and German. More languages available in the near future.
  • Works with Robonova and Robozak MR-C3024 controller boards.
  • Module can be used with any host with an UART interface (powered at 3.3V - 5V) .
  • Simple and robust serial protocol to access and program the module through the host board.
  • 1.77 x 0.95" (45 x 24mm)

  • Protocol / about 13 years ago / 1

    Can this be used for creating sound (not voice) activated devices?

    • AffordableTechnology / about 12 years ago / 1

      I dunno, but description clearly states:
      "Supports up to 32 user-defined Speaker Dependent (SD) triggers or commands (any language)"
      So maybe, if the "sound" that you want to activate a command with, happens to be similar to the sound of ANY word, in ANY language, as spoken by ANY individual - it will work!!!
      Don't forget it also works with ALL known (and unknown) inter-galactic languages as well. So if it is an unusual sound that you need to work, I'd bet you'd find a sufficiently close match in Klingon.
      Best plan is to send an audio tape of your sounds of interest, to the The Klingon Language Institute and they will be able to tell you immediately if any are close to official Klingon words.
      Otherwise, there is an on-line English / Klingon translator which gives pronunciation as well.
      Good luck with the project, I hope you find what you really need!

    Here is a video tutorial on how to make a voice control robot using the VRbot: http://www.youtube.com/watch?v=aUkLd2MncHg
    Apologies if this comes off as self-promotion, I thought it'd be helpful for some people . . .

    Another question... can i connect the module VRbot with my desktop using a simple max232 or i need others boards to use the training software (VRbotGUI)??

  • magykguy721 / about 13 years ago / 1

    Could this work with an Arduino Pro 328?

  • MagiccMan / about 13 years ago / 1

    Is this board based of the HM2007 speech recognition chip?

  • dbudzins / about 13 years ago / 1

    Super excited about this one, but can anyone tell me if it's compatible with non-Arduino controllers? I still haven't jumped on the Arduino train.

  • Surge311 / about 14 years ago / 1

    This may be a stupid question, but is it possible to use this with a stock Arduino? I see in the movie that they are giving COM access to the VRBot through the controller itself, can you do that on a stock Arduino?

    • chrille / about 14 years ago / 1

      This module communicates with an Arduino (or other controller) using a serial interface (RX and TX pins on your Arduino board), so it will work with all Arduinos and Arduino clones.

  • Striker121 / about 14 years ago / 1

    While mighty expensive (Atleast for a cheapo like me), this looks awesome. Would love to see some projects using this. You REALLY have to make a note of this on the front page, not exactly your normal product.
