I'm neither a lawyer nor law student! Neverthless, I know how to pronounce the LEGAL TERMS when I come across them. It's possible because I could read the PHONETIC SPELLINGS. A phonetic spelling (or phonetic transcription) is the WRITTEN FORM of a PRONUNCIATION using SOUND SYMBOLS of the ENGLISH SPEECH SOUNDS. I would recommend those in the legal field to learn how to read the phonetic transcriptions for an appropriate pronunciation of the legal terms.
For example, here's the PHONETIC SPELLING / PRONUNCIATION of the legal term "sine die".
This word has an alternative pronunciation - /ˌsɪneɪ ˈdiːeɪ/
I'll post the phonetic spelling (pronunciation) of legal terms in the comments every now and then. So, keep an eye on this thread.
