Tapes with Grice Reading Greek

Not quite. We do have tapes (at the Grice Collection, Bancroft Library, Berkeley) of Grice speaking English. Will that do? Anyway, this from wiki, under

Letter Rom. Class. IPA Koine IPA Byzan. IPA Cont. IPA before αι ε ει ευ η ῃ ηυ ι οι υ υι Notes
Α α A Ā a ā [a/aː] [a/aː] [a] [a] In Classical polytonic, the length distinction of ᾰ ([a]) and ᾱ ([aː]) is not indicated usually in writing nor in transcription. However, if ᾱ needs to be transcribed, ā suffices.
Β β B b [b] [b] [β] [v]
Γ γ G g [ɡ] [ɡ] [ɣ] [ɣ] [ʝ]
Δ δ D d [d] [d] [ð] [ð]
Ε ε E e [e] [ɛ] [e] [e]
Ϝ ϝ W w [w] N\A Not native to Attic-Ionic (lost in pre-classical times). If pronounced [w], Classical Attic kept it silent and Koine adapted it as ου. If pronounced [β~v], both Classical Attic and Koine adapted it as β.
Ζ ζ Z z [zd] [z/zz] [z/zz] [z/(z)z] Was metrically considered an interchangeably single or double consonant in Koine (typically double between vowels).
Η η Ē ē [ɛː] [eː] [i] [i] Finishes merging with ι/ϊ in Byzantine.
Θ θ Th th [tʰ] [tʰ] [θ] [θ]
Ι ι ϊ I Ī i ī ï [i/iː] [i/iː] [i] [i] In Classical polytonic, the length distinction of ῐ ([i]) and ῑ ([iː]) is not indicated usually in writing nor in transcription. However, if ῑ needs to be transcribed, ī suffices.
Κ κ K k [k] [k] [k] [k] [c]
Λ λ L l [l] [l] [l] [l]
Μ μ M m [m] [m] [m] [m]
Ν ν N n [n] [n] [n] [n]
Ξ ξ Ks ks [kʰs] [kʰs] [ks] [ks] See digraph exceptions further down.
Ο ο O o [o] [o] [o] [o]
Π π P p [p] [p] [p] [p]
Ρ ρ Rh rh r [hr/r] [(h)r/r] [r] [ɾ] Normal ρ is [r] and transcribed r. In Classical, ῥ is voiceless [hr] and transcribed rh, and ρρ or ῤῥ is voiceless [rhr] and transcribed rrh. Koine ῥ is [(h)r], and ῤῥ is [r(h)r]. All are voiced [r] in Byzantine onward, except in Atticist writings.
Σ σ ς S s [s] [s] [s] [s] See digraph exceptions further down.
Τ τ T t [t] [t] [t] [t] See diagraph exceptions further down.
Υ υ ϋ Hu Hū hu hū u ū ü [ʉ/ʉː] [y/yː] [y] [i] Originally not a front vowel, the influential Athens dialect articulates it as [y/yː] earlier on. Merges with ι in 10th century Byzantine Greek, but merges with ου in the Old Athenian dialect until it becomes extinct in the 20th century.
Φ φ Ph ph [pʰ] [pʰ] [ɸ] [f]
Χ χ Kh kh [kʰ] [kʰ] [x] [x] [ç]
Ψ ψ Ps ps [pʰs] [pʰs] [ps] [ps] See digraph exceptions further down.
Ω ω Ō ō [ɔː] [oː] [o] [o] Merges with ο late in Koine.

[edit] Vowel digraphsSpelling Rom. Class. IPA Koine IPA Byzan. IPA Cont. IPA Notes
Αι αι Ai ai [aɪ] [ɛː] [e] [e] Merges with ε in late Koine among the Hellenists and in Alexandria, and treated as an allophone of it from then on.
ᾼ ᾳ Āi āi [aːj] [aː] [a] [a] Classically spelt ΑΙ. In Koine, becomes collated simply as α as they merge.
Αυ αυ Au Āu au āu [aʊ/aːʊ] [aw/aːw] [av] [av] See αυ/ευ/ηυ exceptions further down.
Ει ει Ei ei [eː] [iː] [i] [i] In the learned Koine pronunciation of the foreign Romans, ει was typically an allophone of η immediately before other vowels, and an allophone of ι everywhere else. Alexandrians treated it as an allophone of ῑ in all circumstances, a trend that would become standard in Byzantine.
Ευ ευ Eu eu [eʊ] [ɛw] [ev] [ev] See αυ/ευ/ηυ exceptions further down.
ῌ ῃ Ēi ēi [ɛːj] [eː] [i] [i] Classically spelt ΗΙ. In Koine, becomes collated simply as η as they merge.
Ηυ ηυ Ēu ēu [ɛːʊ] [eːw] [iv] [iv] See αυ/ευ/ηυ exceptions further down.
Οι οι Oi oi [oɪ] [yː] [y] [i] Merges together with ῡ and υι in Koine, even earlier in Athens.
Ου ου Ou ou [oː] [uː] [u] [u] Becomes [uː] earlier on in Athens, remaining an allophone of [oː] until ω fills that pronunciation.
Υι υι ϋι Hui hui ui üi [yː] [yː] [y] [i] Merges with ῡ in Koine, and earlier on in Athens.
ῼ ῳ Ōi ōi [ɔːj] [oː] [o] [o] Classically spelt ΩΙ. In Koine, becomes collated simply as ω as they merge.
Ωυ ωυ Ōu ōu [ɔːy] [oːy] [oy] [oi] Non-Attic Greek diphthong (originally pronounced [ɔːʊ]), separated into two separate vowels, ωϋ, when loaned into Classical Attic onward.

[edit] Consonant-ι exceptionsEven today, most words of learned Ancient Greek origin have ι pronounced as [i], always a full vowel in its own syllable. However, where ι is understood to have come from [j], a [j]-derived pronunciation may reasonably apply. [j] does not enter the spoken language until the Byzantine period, and some words (such as Ἰούλιος) do not today have retroactive [j] pronunciations. But when [j] does contextually apply, this is how.
