Reuse a "No" from game assets

I'm trying to reuse a recording of a "No" response with an NPC that is set to the voice type "Male Sly".

Currently, I have a dialog fragment script that calls:

myQuest.showLocalChest(akSpeakerRef)

The myQuest variable is correctly cast as my own quest-script and the called method does this:

akSpeakerRef.say(Topic_No)

Where Topic_No is initialized to FreeformWindhelmANO.

What I'm asking about is how can I find a simple "No" response among the hundreds of Topic forms (that will work for any of the default voice types)?

If that's too complex, I'd settle for a simple example that uses the say() method of ObjectReference in a successful way.
