We are excited to introduce the brand new third generation of our EasyVR product line: the EasyVR 3!

Here are the main features immediately available and also some anticipations of what will be available soon with a simple firmware upgrade.

EasyVR 3 Features:

  • Up to 32 user-defined Speaker Dependent (SD) or Speaker Verification (SV) commands, that can be trained in ANY language.
  • A selection of built-in Speaker Independent (SI) commands for ready-to-run basic controls, in the following languages:
    • English (US)
    • Italian
    • German
    • French
    • Spanish
    • Japanese
  • Up to 28 custom Speaker Independent (SI) command vocabularies with a QuickT2SI™ Lite license.
    Supported Languages:
    • US English
    • British English
    • French
    • German
    • Italian
    • Japanese
    • Korean
    • Mandarin
    • Spanish
  • Up to 22 minutes of pre-recorded sounds or speech at the maximum compression rate
  • DTMF tone generation
  • SonicNet™ technology for wireless communications between modules or any other sound source (Audio CD, DVD, MP3 Player)
  • Differential audio output that directly supports 8Ω speakers
  • Standard UART interface compatible with CMOS/TTL levels at 3.3V to 5V
  • 6 General purpose I/O lines that can be controlled via UART commands
  • Simple and robust documented serial protocol to access and program through the host board
  • Easy-to-use Graphical User Interface to exercise all the module functions (all the software is Windows only).

Main differences with EasyVR 2.0:

  • Different form factor:
    • External dimensions 25.4 mm x 56.4 mm (1.00” by 2.22”)
    • All signals are available on standard 2.54mm headers
    • Compatible with solder-less breadboard and standard prototyping boards
    • Compatible with mikroBUS™ host interface (see www.mikroe.com/mikrobus)
  • Larger Flash memory for custom SI vocabularies and compressed sounds
  • Serial Flash memory instead of EEPROM to support voice recording capability
  • Audio output from internal DAC instead of PWM for better quality
  • Embedded boot-mode circuitry to support easier connection with a PC (through the QuickUSB adapter cable)
  • SMD jumper for input voltage selection

The current production version of the new EasyVR 3 will be functionally equivalent to the old EasyVR 2. Future firmware upgrades will add voice recording and playback capability to the serial command protocol and a replacement firmware will provide direct programmability of the main processor in the same fashion as the now end-of-life SmartVR product.

EasyVR Shield 3

The new EasyVR Shield 3 comes as an adapter board for using the EasyVR 3 module on Arduino boards.

EasyVR Shield 3 Features:

  • Compatible with Arduino boards that have the 1.0 Shield interface (UNO R3) and legacy boards including, but not limited to:
    • Arduino Duemilanove
    • Arduino Uno
    • Arduino Mega
    • Arduino Leonardo
    • Arduino Due
  • Supports 5V and 3.3V main boards through the IOREF pin
  • Supports direct connection to the PC on main boards with a separate USB/Serial chip and a special software-driven “bridge” mode on boards with only native USB interface, for easy access by the EasyVR Commander
  • Supports remapping of serial pins used by the Shield (in SW mode)
  • Provides a 3.5mm audio output jack suitable for headphones or as a line out

Main differences with the previous version:

  • Support for 3.3V levels in addition to 5V
  • Complete support for Arduino Leonardo and Due (also for Flash updates)
  • SMD jumpers to re-route serial pins used in SW mode (12-13 or 8-9), to free the SPI interface or to enable SoftwareSerial connection with Leonardo
