Context-based phonetic corrections for entities referenced in audio transcriptions

A transcription error correction system comprising:

• a context-based entity list compiler stored in memory that:
• receives a transcribed utterance pertaining to a conversation;
• accesses conversation context data associated with the conversation;
• based on the conversation context data, determines a contextually relevant entity list identifying entities with contextual relevance to the conversation;
• and
• a phonetic similarity model stored in memory that receives an input including both the transcribed utterance and the contextually relevant entity list, the phonetic similarity model being trained to recognize phonetic similarities between entities and phonetic data;
• and
• a context-based phonetic corrector stored in memory that:
• receives a phonetically relevant entity list generated by the phonetic similarity model, the phonetically relevant entity list including one or more entities from the contextually relevant entity list that have been determined to satisfy a phonetic similarity metric with the transcribed utterance;
• and
• identifies and corrects a transcription error in the transcribed utterance based on the phonetically relevant entity list.

One or more tangible computer-readable storage media encoding processor-executable instructions for executing a computer process comprising:

• obtaining conversation context data associated with a conversation or participants of the conversation to compile a contextually relevant list of entities with contextual relevance to the conversation;
• providing a phonetic similarity model with an input that includes both a transcribed utterance from the conversation and a biasing parameter that identifies the contextually relevant list of entities, the phonetic similarity model being trained to recognize phonetic similarities between entities and phonetic data;
• receiving, from the phonetic similarity model, a phonetically relevant entity list including one or more entities from the contextually relevant list of entities determined to satisfy a phonetic similarity metric with the transcribed utterance;
• and
• correcting a transcription error in the transcribed utterance using an entity name included on the phonetically relevant entity list.
