How to speak without moving your lips (Ventriloquism)

Hi everyone!
I have been thinking about writing a new post on blog for like past 4 days but was so busy that couldn't managed to do so. But today I finally decided to write one.
So today, I am going to teach you  "how to speak without moving your lips" or  basic ventriloquism.

 Learn to speak without moving your lips. 

• Let me tell you something that would surprise you, You my friend are already half ventriloquist! so is everyone! don't get it? let me explain it to you. Slightly open your mouth and now try saying these alphabets 

A,  E, C, D, G, H, I, J, K, L, N, O, Q, R, S, T, U, X, Z

• Successful? you must be! So that was easy. 
• Now let us move to the tricky part.  Hold a finger over your mouth as if trying to tell someone to be quiet. This will help prevent your lips from moving. 
• You'll notice that the letters "b," "f," "m," "p," "q," "v," and "w" will make your lips move. 
• To say these without moving your lips, you must use substitutions. For "b," say "d" or "geh." For "f," say "th." For "m," say "n," "nah," or "neh." For "p," say "kl" or "t." For "q," say "koo." For "v," say "th." And for "w," say "ooh". 
• You may think the new words with the substituted letters sound ridiculous, but if you learn to put the stress on the syllables that don't contain these letters, the words will begin to sound natural.
