What are palatal consonants?

How many palatal consonalt's do you have?

1. can't you
2. could you
3. miss you
4. is your

In the four cases, we can find palatalization. The t,d,s,z sounds are changed into palatals when they are pronounced as a linking sound. It's hard to write down the phonetic symbols here.

Is my explanation correct?

Your explanation is partially correct.

Palatal consonants are a type of consonant sound that are produced by the tongue coming into contact with the hard palate, which is the roof of the mouth towards the back. Examples of palatal consonants include /j/ as in "yes" and /ʃ/ as in "she."

However, the examples you provided are not all palatal consonants.

In the four cases you mentioned:
1. "can't you" - The /t/ sound is not palatal, it is an alveolar consonant.
2. "could you" - The /d/ sound is not palatal, it is an alveolar consonant.
3. "miss you" - The /s/ and /z/ sounds are not palatal, they are alveolar consonants.
4. "is your" - The /s/ sound is not palatal, it is an alveolar consonant.

So, none of the examples you provided have palatal consonants.
