Training speech recognition systems using word sequences

A method comprising:

• obtaining first audio data of a communication session between a first device of a first user and a second device of a second user, the communication session configured for verbal communication;
• obtaining, during the communication session, a text string that is a transcription of the first audio data from an automatic transcription system;
• selecting, during the communication session, a contiguous sequence of words from the text string as a first word sequence;
• comparing, during the communication session, the first word sequence to a plurality of word sequences obtained before the communication session, each of the plurality of word sequences associated with a corresponding one of a plurality of counters;
• in response to the first word sequence corresponding to one of the plurality of word sequences based on the comparison, incrementing, during the communication session, a counter of the plurality of counters associated with the one of the plurality of word sequences;
• after incrementing the counter of the plurality of counters, deleting the text string and the first word sequence, wherein the first word sequence is deleted during the communication session;
• and
• training, after deleting the text string and the first word sequence, a language model of the automatic transcription system using the plurality of word sequences and the plurality of counters.
