The following transcription of Biblical Hebrew is based on the system expounded in:
P. Joüon, T. Muraoka, A grammar of Biblical Hebrew (1996),
which differs somewhat from the original edition: P. Joüon, Grammaire de l’hébreu biblique (1947).
Of the two (or several) possibilities mentioned in this book the one fitting better into the general scheme is always chosen, the others being listed under “Alternatives”.
