vicCONTROL Industrial Usage
Starting the Demo Program
The Boot Sequence
Before you can start working with the demo applications, you will need to make sure the phyBOARD-Mira is set to
the correct boot sequence.
On the bottom of the phyBOARD-Mira is a switch controlling the boot sequence (either internal memory or SD card).
The default setting (the boot switch set to OFF) begins booting from the internal memory. To change the boot
sequence, power off the phyBOARD-Mira, and move the switch from OFFtoON:
10 phyBOARD-Mira Boot Switch (S2)
- Booting from internal memory (boot switch set to OFF) will start the pre-loaded
demo Washing Machine.
- Booting from the SD card (boot switch set to ON) will start the preloaded
vicCONTROL Industrial Demo
- Industrial Paper Cutting Machine.
then power the board back on. The system will boot using the chosen boot sequence.
Boot Switch set to OFF - Washing Machine Demo
By default, the boot switch on the phyBOARD-Mira is set toOFFand the demo"Washing Machine"will automatically
start after the board has been powered on.
Tip
The boot switch on the phyBOARD-Mira has only one label:ON. To avoid confusion when selecting the
boot sequence, the side not labeled is considered to beOFF.

11 Washing Machine Demo in different languages - left: German; right - Mandarin
Say the wake-up phrase. This will allow you to control the setting on the screen.
Inside the"Washing Machine"screen, you can say the wake-up phrase, for example:"Hallo Waschmachine", and
then a command phrase.
After the wake-up phrase and before issuing a command, you should wait for the system to respond with a short
tune and highlighting of the wake-up phrase on the screen. This is, however, optional. You can also say the wake-up
and command phrases at once, without a pause in between.
In general, the system supports two tasks (or intents):
Selection of a program or changing its parameters by voice: The system provides natural language input and
will try to follow any reasonable command that you provide by voice. You can set a program or any of the
parameters here or even many at once.
Warning
The"Washing Machine"application is fordemonstration only. Itcannotbe used as a starting point for
your own applications.

Tip
The German version is the default setting for the "Washing Machine" demo. You can return to the main
menu with the button in the upper left corner and select another recognition language from there. This
can only be done if there is a mouse or touch screen attached to the pyhBOARD-Mira.

Tip
The wake-up phrase is different for each language but is shown on the screen. For example, in the German
version, you might say:
* Hallo Waschmaschine, Kockwäsche 90°C, 1200 Umdrehungen, extra Spülen,
fertig in 5Stunden!
* Hallo Waschmachine, wie lange dauert das Programm noch?

Tip
You do not have to follow this format exactly when talking to the application. The system should be able to
understand natural speech.

13 Industrial Paper Cutting Machine Demo
Similar to theWashing Machinedemo, simply say the wake-up phrase followed by a command, for example:
Hey machine, turn on.
Hey machine, set the paper size to A5, 500 pieces.
Command-Line Example App
After logging in, you can run the command line (CLI) demo with the following command:
demo_speech_cli
•
•
•
Tip
Audio input and output can be tricky and has many components involved (microphone, amplifier, casing,
the room's acoustic you are in, the noise inside the room, speaker distance, etc.).
The demo is meant to be used in relatively quiet office environments.
The speaker should be within 1 meter of the microphone and there should be no obstacles in the
way.
The system can also work with USB audio input and output devices. If you would prefer to use USB
audio inputs or outputs, seeSetting USB Input and Outputon how to manually change the settings.


L-856e.A1 phyBOARD-Mira Voice Control Kit Quickstart
The application will print the recognition results for the running speech application (the Paper Cutting Machine
demo by default). The user can also input the name of an audio prompt that is included in the application and the
prompt will be played.The application can also serve as a sample Python implementation for communication
between a user application and the rest of the recognition system. The code for the application can be found in:
/opt/speech/example/cli/speechapp_mqtt.py
