Claim 14:
15. A system for correcting automatic speech recognition (ASR) errors comprising:
one or more processors; and
a memory in communication with the one or more processors and storing instructions that, when executed by the one or more processors, are configured to cause the system to:
receive a transcription comprising one or more transcribed words;
determine that at least one transcribed word of the one or more transcribed words does not exceed one or more respective predefined confidence levels;
generate, using a first machine learning model, a first predicted word;
generate, using the first machine learning model, a first numerical representation of the at least one transcribed word and a second numerical representation of the first predicted word;
calculate a distance between the first and second numerical representations;
determine that the distance exceeds a predefined threshold;
retrieve a first list comprising a plurality of predefined red flag words;
determine that at least one of the plurality of predefined red flag words corresponds to a context of the transcription by iteratively substituting each predefined red flag word of the plurality of predefined red flag words for the at least one transcribed word; and
classify the transcription as being associated with a first category.
