Turning a shouting cat into a talking cat

[Needanadultgapyear]

My house panther spends a lot of time shouting at me - really getting in my face a loud miaowing about something.
So I am considering teaching her to hand human words through the talking buttons. I know it’s a long slow process teaching the words. Has anyone done this?
I am also working on implementing the new icat care recommendations of smaller more frequent meals, but using Kongs and treat balls to further enrich their environment. The photos shows about 5% of the current environmental enrichment and the shoots madam herself.

Has she always been loud? If not then she could be experiencing hearing loss.

Oh she has always been loud. She doesn’t have hearing loss as she can hear a fractional movement of the dreamies box.
I am a vet who is becoming more and more interested in cat behaviour and how often we are failing to meet the needs of pet and particular indoor cats. I am about to implement the five a day felix feeding program for my own cats to also see if this helps her shoutiness - she is an indoor cat by choice her sisters all go out on adventures murdering things.
