Phonetic characters of Arabic emphatic consonants

Question

My native language is Korean. I'm not learning Arabic, but I'm curious anyway.

Refer to the following link for the letter names I recorded myself: Arabic pharyngeal consonants

I think I can pronounce plain /ħ/ and /ʕ/ properly.

For the pharyngealized fricatives /sˤ/ and /zˤ/, I understand them as coarticulated [s͜ħ] and [z͜ʕ]. Is this a correct analysis?

For /dˤ/, I tend to realize it as implosive [ɗ]. Is this an acceptable allophone?

For /tˤ/, I'm not even sure what I'm realizing it as. Is it a pharyngeal-released affricate?

Did I pronounce them properly?

As the comments say, I pronounce them properly. So I have a remaining question. Did I phonetically analyze them correctly? (Essentially, the questions above.)

Answer 1

"Co-articulation" and/or "double articulation" is something the IPA has a hard time representing. And to a first approximation, [s͜ħ] isn't wrong. ص does indeed involve two constrictions, one up in the front of the mouth where [s] happens, and one back in the pharynx where [ħ] happens.

The reason it's not usually transcribed this way is that not all constrictions are created equal. Think of other doubly-articulated consonants like [kʷ]. The constriction at the velum is complete, blocking off the airflow entirely, but the constriction at the lips is weaker and only serves to "color" the sound. A "true" co-articulated consonant requires two roughly-equivalent constrictions, like [k͡p].

Similarly, the back constriction in ص isn't as complete as in [ħ]: it's more like an approximant than a fricative. So the typical IPA rendition treats it as a "coloring", like the labial articulation in [kʷ], and marks it with a superscript instead of a full letter: [sˤ]. The superscript ˤ is shorthand for "pharyngeal-colored" or "with a weak/secondary pharyngeal articulation", just like ʷʲˠˀ for "labial", "palatal", "velar", and "glottal" respectively.

Answer 2

For the pharyngealized fricatives /sˤ/ and /zˤ/, I understand them as coarticulated [s͜ħ] and [z͜ʕ]. Is this a correct analysis?

No.

For /dˤ/, I tend to realize it as implosive [ɗ]. Is this an acceptable allophone?

No.

For /tˤ/, I'm not even sure what I'm realizing it as. Is it a pharyngeal-released affricate?

No.

The pharyngealized consonants in Arabic are produced by spreading and flattening the back of the tongue. There is no co-articulation involved.
