While wearing my Bose A20 connected to my iPad via Bluetooth and while Goose is connected to ForeFlight and reading me the frequencies from a requested airport (e.g., “Goose, what are the frequencies at KAVL?”), Goose is not stopping narration when I say any of the stop words: stop, silence, be quiet, shut up. I’m unable to interact with Goose again until it reads off every frequency listed in ForeFlight for that airport.
Hi @PerryQuatro,
thanks for your feedback and the reported bug!
It’s good, that you found it - thanks. Sorry, that you had to though 
I admit, I was surprised, as I never experienced that myself. However, after testing it, I could recreated your problem.
One important thing - potentially relevant to other readers
Interrupting Goose only works when an aviation headset is connected. No headsets, AirPods and other “regular” headphones do not offer this (listening & talking) kind of capability.
Again: To give commands (such as “stop!”) to Goose, whist Goose is talking, requires a connected aviation headset!
You can interrupt Goose, when you in a procedure (e.g. checklist) and have your aviation headset connected. Please test that. As soon as you start a checklist, this issue should not occur. The “stop” functionality however, is currently not globally available, and does not work for example when you are not in a procedure. This is definitely a bug and will be addressed!
After a quick trouble shoot with my colleague, we are confident to have a solution. Introducing the “stop”-functionality globally through Goose will be introduced with the next update (probably within the next 3-4 days). Please keep an eye out for V6.1.4
I would like to address one other aspect:
Just to clarify, this is technically not correct. Eventhough you are right, that it does feel like it. 
All the frequencies and airport information are “stored” in Goose directly and need to be downloaded (Settings > Download Airports) prior to accessing them. Since we are always striving for correct and current data (and I assume so does ForeFlight), we mostly provide the same information as EFB providers. The information are however coming from a different source.
There is also no requirement for having ForeFlight (or any EFB for that matter) to have access information in Goose via voice.
That all being said, I hope you can give us a few days to resolve this issue for you, Perry.
Again apologies for the inconveniences.
In the mean time - if you ever do need to shut up Goose - you cal always mute it, by clicking the green volume button on the top right.
I hope my answer helped you. Your feedback did anyways!
Many thanks & happy landings

Your reply about the airport info being stored locally makes sense; thanks for that clarification. Looking forward to the bug fix. Cheers!
no worries!
happy to help.
