Voice Assistant - Mute for hours, then a literal blabbermouth?

Just this morning, one of my voice assistants began spouting many, many fragments of many responses, presumably queued up and buffered from the last 24-to-36 hours. Anyone else noticing similar behavior? I just wanted to break up laughing, but was participating in a voice conference at the time. (of course!)

Hours later this afternoon, it did it again. :crazy_face:
