Sorry to disappoint you with the pronunciation, but I understood from your question that you want the answer in Arabic. This gave me the idea that you won’t need any tranlitiration hints.
In any case, here are the pronunciations:
One nameless spirit:
روح تفوق الوصف
Roohon tafooqo alwasf (feminine) (Inexpressible)
روح يفوق الوصف
Roohon yafooqo alwasf (masculine)

روح غير قابلة للتعريف
Roohon ghiar qabilah lit-ta’reef (feminine) (indefinable)
روح غير قابل للتعريف
Roohon ghair qabell lit-ta’reef (masculine)

روح تجل عن الوصف
Roohon tajil-lo ‘an alwasf (feminine) (indescribable)
روح يجل عن الوصف
Roohon yajil-lo ‘an alwasf (masculine)

روح يكتنفها الغموض
Roohon yaktanifuha alghomood (feminine) (obscure)
روح يكتنفه الغموض
Roohon yaktanifuho alghomood (masculine)

(only) one nameless spirit:
only = faqatt فقط , one = wahid واحد (m) and wahidah واحدة (f)
روح واحدة فقط يكتنفها الغموض
Roohon wahidah – faqatt- yaktanifuha alghomood (feminine)
روح واحد فقط يكتنفه الغموض
Roohon wahid - faqatt- yaktanifuho alghomood (masculine)

Ghost: shabah شبح (masculine) (the letter h in roohon, shabah and wahid/ah is produced from the middle of the throat, moving towards the mouth. It is an emphatic h, the non emphatic h sounds like the English h in hat.)
Spectrum: tayf طيف (masculine) (t is an emphatic t , sounds heavier that t in but, when pronouncing it the back part of the surface of the tongue should be raised)
