Is your feature request related to a problem? Please describe.

When multiple onju voices detect the wakeword at the same time, HA cancels all but one pipelines (good!). This triggers the on_error handler on the cancelled devices though, which then play the on_error sound.

Describe the solution you'd like

A runtime configuration switch which allows turning off of the on_error sound.

Describe alternatives you've considered

It would be nice if HA would allow a differentiation between error types, but I don't think it does? Then we could choose when to play the sound.

I think this should be fixed in ESPHome rather than the config. I will look into it when i get back from vacation
