Mornings: the obvious choice is irish given its the first thing most people think of when they think irish. But I'd say what we need in the morning, rather than catchphrases (which would soon get annoying), we need a tone and phrase that suggests something is to be looked forward to. Give us that umph in the morning. For that reason I'd have to go for scouse. We all get a bit phlegmy in the morning and what better way to feel included than an accent that reek "HACK IT UP LA"
At noon we all need a pat on the back to accompany lunch. Following a morning of work tasks, errands run, kids packed off to school or house work done, we need an auditory experience that comes in a 'good job, keep going' flavour of cockney london. We've got a love hate for that cockney jive that gives us the keep it going in the form of...you know, as bad as cockney is, my god it beats jafaican (anything does. It's awful and sounds so fake. Stop doing it.)
At home time we come in for tea, head for a workout, veg out by the tv...we need the gratitude filled tones with an arsenal of phrases oozing with appreciation. We need a bit of Birmingham. What better tones than Jasper Carrot when he's not dropping golden balls (the tv show, he's not k.o'd Becks) but with a nice cup of tea to toast a productive day.
I've gone for a fairly standard day, no emergencies or calls to action as we often encounter...holidays... But for most standard days mornings require scouse, noon cockney, evenings the somber tones of the brum maybe followed by, in a reverse of my first assumptions, musical irish tones to nod off to at night.
Maybe just my preference, I once had a now album on my walkman with 3 disks I'd skip through, without fail though Bellefires perfect bliss always sent me off
