Voice notes skill

[phirsch]

It would be great if there was a skill to record (short-ish) audio/voice notes, particularly if this could happen without touching the phone st all (i.e. after activating by wake-word and/or through headset).
It could also be useful to replay all or the last n recordings. Of course, STT on the notes would be helpful, too, but to guard against recognition errors, the audio should be saved anyway.

Ideas for figuring out when to stop the recording:

1. configurable pre-set duration (somewhat inflexible)
2. (configurable) period of silence (could be problematic in noisy environments)
3. triggering Dicio again
4. stop-word detection

Also, it could be helpful to (offer to) periodically emit a tone (through headset?) or vibration signal to the notify user that a recording is still in progress (which could happen if started hands-free).
