+Subject: [PATCH] Fix audio choppiness on some systems
+
+Commit a41d46e816d2 ("Fix cancellation snappiness") made espeak unusable
+on the RaspberryPi due to extreme audio choppiness. This can sometimes
+be observed on some PC-type systems as well, albeit much less
+prominently.
+
+Relax the timing to the smallest value that makes it work again on the
+RaspberryPi.
