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)
- Up to 28 custom Speaker Independent (SI) command vocabularies with a QuickT2SI™ Lite license.
- US English
- British English
- 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.
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
