When do we know les is interpreted as "the" and not thrown out the window as "some"?
"Le banane" sounds exactly like "les bananes", but it is not accepted as a transcription. Bad Duo.
Le sounds similar to "luh" and les sounds about like "lay". They don't sound exactly alike!
Also, it is la banane.
The recording is really poor. I had to listen to 'singe' so many times that I forgot that it was 'la' and not 'les', so got it wrong anyway! 'la' is clear to me but 'singe' is not.
