To hear the pronunciation of the Greek,
open any reference work that contains actual Greek (not the transliteration).
For example, click on Greek/Hebrew > By Verse > Interlinear Bible
The Verse Reference dialog opens.
Enter a New Testament verse, e.g. Matt 5:5
Interlinear opens to Matt 5:5
Double-click on the Greek for the first word (its Strong's number is 3107)
The Word Information panel appears in the lower left, at the bottom of the navigation panel
Click on the speaker/microphone button in that panel
In 10-15 seconds, you will hear the pronunciation over your computer's speakers.
(1) The pronunciation given is for the general form of the word, not its specific form in this verse. To illustrate "general form" in English, let's say that the verse contains the form "looked", then the general form that is pronounced would be "look".
