We first demonstrate that by including more audio context after a detected trigger phrase, we can indeed get a more accurate decision.

We train the network in a supervised multi-task learning setup, where the speech transcription branch of the network is trained to minimise a phonetic connectionist temporal classification (CTC) loss while the speaker recognition branch of the network is trained to label the input sequence with the correct label for the speaker.

Next, we collect a much smaller dataset of examples that are challenging for the baseline system.
