Abstract
A method may include obtaining first audio data of a communication session between a first device and a second device, obtaining a text string that is a transcription of the first audio data, and selecting a contiguous sequence of words from the text string as a first word sequence. The method may further include comparing the first word sequence to multiple word sequences obtained before the communication session and in response to the first word sequence corresponding to one of the multiple word sequences, incrementing a counter of multiple counters associated with the one of the multiple word sequences. The method may also include deleting the text string and the first word sequence and training and after deleting the text string and the first word sequence, training a language model of an automatic transcription system using the multiple word sequences and the multiple counters.
