Audio transcription sentence tokenization system and method

Abstract

A system and method for tokenizing sentences in transcriptions of electronic communication audio files includes one or more electronic data storage systems coupled in electronic communication with an audio receiver. A collection of audio files is stored in the electronic data storage system(s). The audio receiver is configured to receive one or more audio files from the electronic data storage systems. The system also includes a speech-to-text processing engine configured to transcribe the one or more audio files received by the audio receiver to produce input transcriptions. In addition, the system includes a call tokenization engine that stores a list of candidate expressions and expression pairs that are indicative of turn taking and change of context in phone conversations. The call tokenization engine also receives input transcriptions of the one or more audio files from the speech-to-text processing engine, scans each input transcription for the one or more candidate expressions and expression pairs, inserts a punctuation marker adjacent a detected expression when the detected expression is one of the one or more candidate expressions and expression pairs, and outputs a tokenized transcription when the call tokenization engine reaches an end of the input transcription.
