the audio sounds like it has an extra vowel or "ee" sound between the λ and the μ. is this a misrecording or is there some pronunciation principle at work here that i'm missing?
I can hear a "ee" sound too. CAN it be a case of anaptyxis, that is to say the addition of a vowel sound to consonant cluster (in this case λμ) to make it easier to pronounce?
I also hear the "ee" sound, and I hear it in google translate as well. But I think it is an artifact of articulation, not an actual anaptyxis. I can more or less reproduce it by changing the way I form the 'L' consonant. In my native English I use only the tip of my tongue against the roof of my mouth right behind my upper teeth to enunciate "L". This makes what I would describe as a "hard L" sound. The preceding double g ("γγ") in "-άνγγελμα", however, positions my tongue at the back of my throat and encourages me to make a "soft L" sound by putting the middle of my tongue against the roof of my mouth further from my teeth. When I do this relaxedly, I produce a similar 'ee' sound to what I am hearing.
