iphone - iOS App unknown crash issue - [SpeakCorrections key] unrecognized selector -

i use bwquincymanager log app's crash records. , found there lot of crashes this:

terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[speakcorrections key]: unrecognized selector sent instance 0x1f835a20'

i dont know "speakcorrections" is, it's not in source code, or others thirdparty source code used in project. , not in apple's lib, @ least can't find @ developer.apple.com .

and googled error, seems not many helpful informations. can tell me speakcorrections class is?
