Description

MOVI™ is an easy to use speech recognizer and voice synthesizer.  It is used with an Arduino board and provides an alternative to buttons, remote controls, or cell phones by letting you use full-sentence voice commands for tasks such as turning devices on and off, entering alarm codes, and carrying on programmed conversations with projects. MOVI is programmed directly from the Arduino IDE and requires no voice samples for training, does not use an Internet connection and is speaker independent. The code on the left shows an example of how easy it is to create your own voice-based dialog with MOVI.

MOVI™ is plug and play! Plug the shield onto your Arduino Uno or compatible board, connect a power supply and a speaker, and you’re ready to go. Watch this video for a quick introduction to MOVI™. 

MOVI™ has a built-in microphone with automatic gain-control to detect speech up to 10 feet in a quiet environment. Alternatively, an external microphone input is also available and can be used in noisier rooms.

Requirements

Before you get started, you will need the following items to use your MOVI™ board:
  • A 7V to 16V 500mA external power supply that powers MOVI™ through the Arduino board. The power consumption of both boards is just above what the USB port can provide. If you don't have already one, this 9V adapter from Adafruit will work perfectly.
  • An Arduino board!  The Arduino Uno R3, Duemilanove, Mega 2560, or Leonardo will work straight out of the box without any jumper or connection required. Also the Microchip WiFire and uc32. Others such as the Arduino Due, Intel Galileo, Intel Edison, Arduino Yun, and many Arduino compatibles will work with some rewiring. Check out the User Manual  below.
  • A headphones or active speaker connected to the HEADPHONE jack will let you hear the voice synthesizer. As you get started, it provides really good feedback.
  • Optionally, an external microphone plugged in the MIC input will bypass the on-board microphone when the environment you are using MOVI™ in is loud.
  • And of course download and install the MOVI™ sketch for your Arduino programming environment.

MOVI™ Arduino Shield

A cloudless Speech Recognizer / Voice Synthesizer for the Arduino platform
  • MOVI is the easy to use speech recognizer and voice synthesizer Arduino shield
  • Program up to 150 full-sentence voice commands from Arduino IDE with the speech recognizer
  • MOVI is speaker independent. You can carry on programmed conversations with projects with the speech synthesizer
  • MOVI is privacy friendly: No Internet or PC connection required. It is compatible with most Arduino compatible boards
  • Support for Spanish and German (with Firmware 1.1)

Acknowledgments

Creating MOVI™ was possible thanks to many open source packages.

The original source code of all the open source speech related software packages used in the MOVI shield is included on the microSD card it ships with. For convenience, we also include links to the various packages here:
MOVI™ is built on a Debian Linux Kernel using many of the GNU standard tools and libraries such as GLIBC, bash, etc, which are easily found on the Web. We also make extensive use of Python.

MOVI™ was made possible thanks to the support and generosity of our 334 Kickstarter Campaign Backers!
Your contributions enabled us to convert our multi-board MOVI™ prototype into a compact single board MOVI™ Shield for Arduino. We could not have done this without your help!
