Abstract
One of the main challenges of the Internet of Things (IoT) is to enable
end-users without technical experience to use, control or monitor smart devices.
However, enabling end-users to interact with these smart devices in an intuitive and
natural way becomes increasingly important as they become more pervasive in our homes,
workplaces and public environments.
Voice-based interfaces are the emerging
trend to provide a more natural human-device interaction in smart environments.
Such interfaces require Natural Language Understanding (NLU) approaches to identify
the meaning of end-users' voice inputs.
Designing voice interfaces that are
not limited to a small, fixed set of pre-defined commands is far from trivial.
Existing voice-based solutions in the smart home domain either restrict the
end-users to follow a strict language pattern, do not support indirect goals, require a
large training dataset, or need a voice assistant located in the cloud.
In
this paper, we propose an approach for understanding end-users goals from voice inputs in
smart homes.
Our approach alleviates the need for end-users to learn or
remember concrete operations of the devices and specific words/pattern structures rather
it enables them to control their smart homes based on the desired goals (effects).
We evaluate the approach through application to a collection of 253 goals from real
end-users and report on quality metrics.
The results demonstrate that our
solution provides a good accuracy, high precision and acceptable recall for understanding
end-users goals in the smart home domain.
