Voice assistant reply when it doesn't understand

I am loving the year of the voice, however, am also having a lot of misses in the hit and mis usage of the voice assist.
My issue is with the 'sorry I don’t understand ’ reply.
What is most annoying is that if I want to retry a command fast, the audio keeps playing and my new command gets polluted with a part of the sorry reply.

I could thing of a few options myself:

  • can we speed up the TTS reply, configureable?
  • can we have a chime for failure (maybe even different chime for different errortypes)
  • can we remove the ‘sorry’ part? (I dont need my VA to excuse itself)
  • can we setup custom reply (TTS or Audio of D’oh!)
