I have a question regarding the audio. Is the intonation natural for Greek language? The way it sounds to my non-Greek ears now, the question almost expresses surprise/judgement. "Seriously, you have six (!!!) children?!".
Since the audio is all computer generated (TTS) there may be unnatural sounding sentences. This seems like she realized towards the end that she should make it sound like a question. No, it's not a very good example of any kind of question...simple or surprised.
