Make sure you actually stop the air for consonants like ’t’ and ‘b’. Differentiate between your vowels. Don’t expect to speak with perfect clarity right away. You may need to practice this for several hours each day, and you may need to practice more to master difficult words. Practice when you’re alone – in the car, or walking down the street; when cleaning, or knitting, or standing in front of the mirror. You can slow down your syllables in conversation, but you may make more progress if you devote some serious time to honing your speech.

Avoid speaking in run-on sentences. If you let yourself ramble, your listeners might miss the point. Try to break up your thoughts into comprehensible chunks. [3] X Research source

The caveat: you’ll need to make sure that the people you’re speaking to also know these words. Keep audience in mind. Use simpler words, when possible. Reading is a great way to expand vocabulary. Read books, articles, essays; read things that fascinate you, and read things that you wouldn’t normally read. Whenever you come across a word that you don’t know, look it up. Try keeping a list of useful, powerful words. The more you use them in context, the more natural it will feel – and the better your word-selection may become.

Silently say the words to yourself before you say them aloud. This might help you ensure that you’ve gotten the pronunciation right.

For “B” words, try: 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! For “D” words, try: Did Doug dig David’s garden or did David dig Doug’s garden? or Do drop in at the Dewdrop Inn. For “F” sounds, try: Four furious friends fought for the phone or Five flippant Frenchmen fly from France for fashions. For “J” sounds, try: James just jostled Jean gently or Jack the jailbird jacked a jeep.

If you tend to mumble or slur your words, it can be difficult to break from the pattern and speak clearly. When you recite words, try to forget about the fact that you are speaking. Focus only on the words, their meaning, their beauty. Try not to overthink it. [8] X Research source
