Pronunciation: [ɪt ɐ dˈiːl] (IPA) 
The correct spelling for the phrase "it a deal" is actually "it's a deal". The apostrophe in "it's" indicates that the word is a contraction of "it is". The phonetic transcription for "it's" is /ɪts/ which is made up of the short vowel sound /ɪ/ followed by the voiceless consonant /t/ and the voiced consonant /z/. Therefore, the correct way to spell the phrase would be "it's a deal" to ensure proper grammar and spelling.
