When you conduct site surveys, it is often convenient to control
the application without using your hands. With TamoGraph, this can
be achieved by using the operating system’s voice recognition
engine. You can actually “tell” the application what to do using
simple voice commands; for example, “TamoGraph, pause” or
“TamoGraph, pan left”. To configure voice control, click
Settings => Camera and Voice Settings
in TamoGraph and select the
tab. Check the
Enable voice recognition
box to turn on this functionality and select a
Voice input device,
which might be a microphone integrated into your laptop/tablet; or,
better yet, headphones with a microphone; an external microphone
typically provides a much higher voice recognition quality. On
Voice recognition engine
control allows you to select a language to be used, e.g. “English –
US” or “English – UK”. On macOS, you may need to enable enhanced
(offline) dictation. To enable it, open the system preferences
dialog, select “Keyboard”, then “Dictation”, turn on “Dictation”,
enable the “Use Enhanced Dictation” feature, and restart
After configuring the voice recognition parameters, use the
Voice command test
frame to test it. Press
and say one of the pre-set commands:
Zoom in, Zoom out – zooms a floor plan in and
Start – starts a survey.
Stop – stops a survey.
Pause – pauses a started survey.
Resume – resumes a paused survey.
Pan up, Pan down, Pan left, Pan right –
pans a floor plan.
Take photo – takes a photo.
Don’t listen – turns off voice recognition.
Each command must be prefixed with the specified
By default, the prefix is “TamoGraph”, but you can change it to any
other word. The reason why you need to use a prefix is the
following: When voice recognition is enabled, the application is
constantly listening for speech in the microphone. If you talk to
someone while you are surveying and say, for example, “I need to
take a photo”, the voice recognition engine hears the “take a
photo” part and performs the action associated with this command,
although you never wanted it to. To prevent the actions from being
triggered by such phrases, actual commands intended for execution
should be prefixed by a special word (by default,
To test voice recognition, say “TamoGraph, zoom in” or “TamoGraph,
take photo”. If the pronounced command is recognized, you will see
and hear the confirmation message; e.g., “Zoom in ok”. For some of
the commands, you can customize the associated action.
control the percentage of zoom and pan, respectively.
Take photo after (sec.)
controls the time interval after which the photo is automatically
Once you have configured and tested voice recognition, you can
close the configuration dialog and use voice commands to control
TamoGraph. If a command is not applicable now; e.g., pausing a
survey that was never started, you will be notified accordingly.
Voice recognition can be turned on and off using the microphone
icon on the right side of the status bar of the main TamoGraph
