EasyVR 3 is a multi-purpose speech recognition module designed to easily add versatile, robust and cost effective speech recognition capabilities to almost any application.
The EasyVR 3 module can be used with any host with an UART interface powered at 3.3V – 5V, such as PIC and Arduino boards. Some application examples include home automation, such as voice controlled light switches, locks, curtains or kitchen appliances, or adding “hearing” to the most popular robots on the market. It can be easily plugged into a solder-less breadboard or standard prototyping board, and it is compatible with the mikroBUS™ specifications (see www.mikroe.com/mikrobus). Separate male headers are provided inside the package, along with a microphone cable assembly and speaker wires (loudspeaker not included).
- Up to 32 user-defined commands, sub-divided in up to 15 Speaker Dependent (SD) groups, 1 SD trigger and 1 Speaker Verification (SV) group of max 5 commands, that can be trained in ANY language .
- A selection of 26 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 up to 12 commands each , for a total of 336 possible commands.
- US English
- SonicNet technology for wireless communications between modules or any other sound source (Audio CD, DVD, MP3 Player).
- Up to 22 minutes of pre-recorded sounds or speech .
- DTMF tone generation.
- Differential audio output that directly supports 8Ω speakers.
- Easy-to-use Graphical User Interface to program Voice Commands and audio.
- Standard UART interface (powered at 3.3V – 5V).
- Simple and robust documented serial protocol to access and program through the host board.
- 6 General purpose I/O lines that can be controlled via UART commands.
- [NEW!!!] Starting with firmware Revision 1, up to 32 audio messages can be recorded on the fly, for a total of about 120 seconds.
EasyVR Shield 3
The EasyVR Shield 3 is an adapter board for the EasyVR 3 module, designed to simplify its use among the Arduino community.
The Shield is compatible with any Arduino board using UNO-R3 Shield headers, running at either 3.3V or 5V levels, by using the IOREF pin to select the EasyVR operating voltage.
It is also backward compatible with earlier Arduino boards that don’t have the IOREF pin, which are using 5V I/O levels by default.
If your board does not have the IOREF pin but it is running at 3.3V, you can still operate the EasyVR Shield 3 correctly if you manually connect pins IOREF and 3V3 together, for example with a jumper wire.
The board comes with separate Arduino stackable headers for the Shield interface. The EasyVR 3 module is also provided separately.
- 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
- Enables different modes of serial connection and also flash updates to the embedded EasyVR module (through the Mode Jumper)
- 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
