  This paper focuses on wake on intent (WOI) techniques for platforms with
limited compute and memory. Our approach of utterance-level intent
classification is based on a sequence of keywords in the utterance instead of a
single fixed key phrase. The keyword sequence is transformed into four types of
input features, namely acoustics, phones, word2vec and speech2vec for
individual intent learning and then fused decision making. If a wake intent is
detected, it will trigger the power-costly ASR afterwards. The system is
trained and tested on a newly collected internal dataset in Intel called AMIE,
which will be reported in this paper for the first time. It is demonstrated
that our novel technique with the representation of the key-phrases
successfully achieved a noise robust intent classification in different domains
including in-car human-machine communications. The wake on intent system will
be low-power and low-complexity, which makes it suitable for always on
operations in real life hardware-based applications.
