More readings for articulation - these assist clean, clear speech. Difficulties with enunciation (pronouncing words) could be a case of lazy tongue. Record each of these fore meaning – use vocal variety and expressiveness – and clear articulation.

I.

Bill had a billboard.
Bill also had a board bill.
The board bill bored Bill,
So Bill sold his billboard
And paid his board bill.
Then the board bill
No longer bored Bill,
But though he had no board bill,
Neither did he have his billboard!

Mrs Tongue lives in her house, the mouth.

Every morning she mops it from ceiling to floor.

First she sweeps her mop from right to left.

Next she sweeps her mop from left to right.

Then she sweeps her mop from right to left.

And she sweeps her mop from left to right

Now she dusts the furniture from left to right.

Then she dusts the furniture right to left.

Then she shakes out the rug out the window.

And shakes, and shakes, and shakes out the rug, out the window.

Then she shakes out the rug out the window even more.

It’s a downright dirty and dusty duty but has to be done.

Lastly she sweeps away the cobwebs from around the front door.

The cobwebs keep clinging to the cubicle beside the door.

She has to sweep them even more.

Cleaning the house this way every day is always a chore.

To sit in solemn silence in a dull dark dock
In a pestilential prison with a life long lock
Awaiting the sensation of a short sharp shock
From a cheap and chippy chopper on a big black block

What a to do to die today,
at a minute or two to two,
a thing distinctly hard to say,
but a harder thing to do.
For they’ll beat a tattoo at two today
a rat a tat at two,
and the dragon will come when he hears the drum
at a minute or two to two today
at a minute or two today.

'I am the very pattern of a modern Major-General;
I've information vegetable, animal, and mineral;
I know the Kings of England, and I quote the fights historical,
From Marathon to Waterloo, in order categorical;
I'm very well acquainted too with matters mathematical,
I understand equations, both simple and quadratical,
About binomial theorem I'm teeming with a lot o' news,
With many cheerful facts about the square of the hypotenuse.
I'm very good at integral and differential calculus,
I know the scientific names of beings animalculous,
In short, in matters vegetable, animal, and mineral,
I am the very model of a modern Major-General.'
