Some problems on real sequences.

I tried to reproduce your results, but I found that there are two phenomena (bad results) in some real sequences, both of which also appear in the model you provide.
- may be that the filter diverges (the estimated echo energy is unusually high);
- the estimated echo have a howling-like sound (which doesnt exist in the reference signal);
Most of these two happens at the beginning of the sentence(but not necessarily at the beginning of the sequence).
Did you find anything like this?

sry i cant provide them because of privacy reasons. its just some real captured audio. But the audio itself is not special. I blame it on the lack of stability of the filter, maybe some post-processing.
