  Most End-to-End SLU methods depend on the pretrained ASR or language model
features for intent prediction. However, other essential information in speech,
such as prosody, is often ignored. Recent research has shown improved results
in classifying dialogue acts by incorporating prosodic information. The margins
of improvement in these methods are minimal as the neural models ignore
prosodic features. In this work, we propose prosody-attention, which uses the
prosodic features differently to generate attention maps across time frames of
the utterance. Then we propose prosody-distillation to explicitly learn the
prosodic information in the acoustic encoder rather than concatenating the
implicit prosodic features. Both the proposed methods improve the baseline
results, and the prosody-distillation method gives an intent classification
accuracy improvement of 8\% and 2\% on SLURP and STOP datasets over the prosody
baseline.
