Quick question: I thought that ευ and αυ, were only "ev" and "av" right before consonants, but the audio for this sentence pronounces μαγειρεύει as though it were "μαγειρέβη", even though the εύ is not before a consonant. Is this correct? And if so, is that just the usual way to pronounce ευ and αυ, even without a consonant after?
Αυ & ευ are pronounced as αΦ and εΦ when ξ, ψ or a voiceless consonant follows, namely κ, π, τ, χ, θ, φ, σ, and when they are at the end of the word. Αυ & ευ are pronounced as αΒ nad εΒ when ζ, a vowel (α,ε,η,ι,υ,ο,ω,) a dipthong (αι, ει, οι, ου) or a voiced consonant (γ, β, δ, λ, μ, ν, ρ) follows.
