Is it 'the' dog whisperer aka Cesar Milan? If so then I'd probably use said article to line the bottom of the cat's litter tray 
If it is Cesar Milan I don't think he would advocate speaking at all so it must be someone else. I have tried Cesar's methods of "tssssing" and pointing to my friends Cavaliers with successful results. One off them knows sign language because he is not deaf. He can also lip read "biscuit"!
In what context did you use these methods? and please do describe the positive results you achieved.

The context it was used was whilst at my friend's house we had a Chinese takeaway delivery at the kitchen door. My friend's method of control is to shut the door on the dogs and let them carry on barking and pogo-ing, which they do because it's a glass door and they can see the delivery person. I opened the door, blocked them with my body (legs really), "tsssss"ed at them and pointed to their beds in the living room. Initially they tried to squeeze past me but I'm not one for giving up easily and moved around so that they couldn't get past me. I then moved towards them so they knew I meant business, they then backed off and retreated to their beds. I didn't have to say a word, they could tell from my body language and the "tsssss" that their barking and pogo behaviour was not acceptable.
I also apply this to my partner's mother's Dachs x although she's a tougher nut to crack! She's far more persistent and the problem being she doesn't get any consistent training from "mum" or my partner. They both spoil her rotten as she's a rescue and small and they feel sorry for her ... still after four years!! She's a lovely little dog and she's very lucky to live with "mum" but the spoiling her means she get's away with murder.
Hope this helps. 
The reason I asked is cos I'm not a great fan of threatening and intimidating my dogs to get them to do what I want, and as I thought you have just demonstrated that is the angle you took in this case.
If it worked for you then fine but what have you taught the dogs?
Does your friend now use this method?
How do you think these dogs feel about someone coming to the door in the future if when they do they get threatened every time?
These methods may work for a time but they are teaching the dog nothing apart from you are someone to be afraid of and is that what you want?
This is what Cesar Milan calls dominance, personally I call it bullying.
I am the leader in my house and have the most wonderful relationship with my boys, I don't need to intimidate or threaten. A wild alpha wolf is the provider not a bully and this is where Milans interpretation of what being Alpha is all about hits a bit of a snag.
There is too much confusion regarding the term dominance and it is and has been completely misused by many dog trainers to disguise what in some cases was physical and mental abuse directed at the dog. I admit I was guilty of this before I knew better.
Far better to train an appropriate response or manage the situation better in the first place than go down this route.
Punishment can go wrong and can lead to worse behaviour in the long run.
This method suppresses the behaviour and does not address the root of the problem and is often only a temporary fix.
As for Jan fennel well I have read all her books and enjoyed them until I realised through experience and wider study that I did not agree with a lot of what she said either. The thing with these guys is they are on the TV so they must be right, well so was Barbara woodhouse and she talked some absolute c**p too.
Milan and Fennel both rely on outdated dominance, wolf pack theory models that have been argued by leading academics to be inappropriate and misleading when it comes to the domestic dog.
Dogs through many generations of artificial selective breeding are not wolves and do not live as such so why try to impose wolf pack rules? (which are misinterpreted anyway by these peoplein the first place.)
Having studied canine behaviour to degree level it is now fairly easy for me to spot both the merits and failings of both Milan and fennel but there are a lot of armchair dog trainers out there who know no better and get sucked in.
I would reccomend you have a look at Dominance fact or fiction, the culture clash and the complete idiots guide to positive dog training to get a different outlook and see if you still agree with Milan and fennel.
