It might not be intended, but this sentence seems like a good illustration of the difference between "δ", that despite being the fourth letter in the alphabet sounds like a voiced "th" while the "d" sound is found through "ντ".
That wouldn't be the first mistake Google has made. Try this for verification.

Megaphone? Really? This is beginning level for the alphabet. Is that standard vocabulary in Greek preschool? Crazy
Actually, in preschool, it's much easier to teach the children how to read. The learners may be young but their level of Greek comprehension is higher than the average non-Greek speaker. The preschool child already understands and uses a great many words and knows by basic syntax through using the language.
We must assume that those who are learning Greek as a second language do not know any words or even the alphabet. However, they do have experience in at least their native language which will be a foundation for the new language.
Thus we are trying to teach the alphabet in the first skill using simple words.
Before the word "megaphone" is introduced there have been exercises with"
LESSON 1 α,ανανάς, άλφα, το, ο, όμικρον, ν, γραμμα,
LESSON 2 κ, κακό, δάδα, μαμά, μ,
μι, δ, δέλτα, κάππα LESSON 3 λ,, λάμδα, καλό, ε, ελένη, η, έψιλον, ταυ,τ LESSON 4 γ, γεγονός, ιλιάδα, ήδη, ήτα, γάμα, γεγονός, μπαμπάς, ι γιώτα LESSON 5 λουλούδι, π, και, ποπ κορν, ξυλόφωνο, ξ, ντουντούκα
