"Connected Speech" is when words in the English language are linked and connected to each other to form a new sound. Words like "gonna, wanna and gotta" are the most common words that are used in everyday conversation. These are definitely very useful when speaking to native speakers, because this is how native speakers actually speak.
It is never wrong to use these shortcuts in your conversations in English. Please try them! I hope this lesson will help you improve your pronunciation and fluency in speaking.
Remember, practice is the key. Practice. Practice. Practice.
