  Question: What was the current technique and its limitations?
  Answer:
output: Current speech alignment techniques assume that foreground speech must be continuous and, barring some isolated words and backchannels, can not cope with overlapping background speech. Performing adaptations on both the foreground and background speaker produced a new variety of misalignments, a problem resulting, in part, from the fact that background speakers often match better to foreground conditions.
