Try reading

     Find a document to read, something about two pages in length - the first few pages of a book would work well.

     Read your document through silently first, then read it aloud in your normal speaking voice.  Don't worry if you stumble or falter, just pick up and continue to the end.

Now read it a third time, recording your voice if possible and remember:

• Slow down: It is a natural reaction to want to get it over as fast as possible and this often causes people to stumble over their words. Speeding up also occurs when you are nervous and usually makes you more difficult to understand.
• Keep your head up: Try not to tuck your chin into the book as your voice is then addressing the floor. Hold your book higher and project your voice.
• Pause occasionally: Let the end of a sentence or the end of a paragraph give you a chance of a small, two or three second rest. Pauses can be useful for emphasis.
