Transcription System Audio-Text Position Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in reviewing the accuracy of transcribed text reports from audio files, particularly in healthcare settings, where radiologists must repeatedly guess and rewind audio files to verify accuracy, leading to time-consuming and labor-intensive processes.
Innovation Solution
A method and apparatus that correlate positions in the transcribed text report with corresponding positions in the audio file, using voice recognition to identify word matches, and augment the text report with selectable icons to efficiently navigate and playback specific audio segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reviewing radiologist listens to the entire audio file to verify accuracy, then the review is thorough, but the process becomes time-consuming and inefficient
Solution Approach 1:
The audio file is divided into multiple segments, each corresponding to a specific portion of the transcripted text report. The radiologist can selectively review only the audio segments associated with specific text portions that need verification, rather than listening to the entire audio file. This segmentation enables targeted review while maintaining accuracy verification.
Solution Approach 2:
The system pre-processes the audio file by segmenting it and associating each segment with the corresponding transcripted text report portion before the radiologist performs review. This preliminary segmentation and association work is done automatically, allowing the radiologist to directly access specific segments without manual navigation or guessing during the review process.
2Ease of operation
If the radiologist repeatedly fast forwards and rewinds to find specific audio portions, then the desired audio segments can be accessed, but the workflow becomes labor-intensive and inefficient
Solution Approach 1:
The system introduces an intermediary interface that links the transcripted text report with the audio file segments. This interface automatically identifies and presents the relevant audio segment corresponding to the text portion the radiologist is reviewing, eliminating the need for manual fast forwarding and rewinding. The intermediary layer handles the complex task of audio navigation based on text position.
Solution Approach 2:
The manual mechanical process of fast forwarding and rewinding the audio file is replaced with an automated electronic system that uses text position information to directly jump to and play the corresponding audio segment. This substitution eliminates repetitive manual operations and enables efficient navigation.
3Ease of operation
If the radiologist guesses the proper position in the audio file, then navigation to audio segments may occur, but the guesses are not always correct leading to repeated adjustments
Solution Approach 1:
The system provides feedback by automatically identifying and displaying the exact audio segment position that corresponds to the current text portion being reviewed. This feedback mechanism eliminates guessing by showing the radiologist precisely which audio segment will be played, ensuring correct positioning on the first attempt and preventing repeated adjustments.
Solution Approach 2:
The system performs preliminary calculation and identification of the correct audio position based on the text position before the radiologist needs to navigate. This pre-computation of audio positions ensures that when the radiologist interacts with the system, the correct audio segment is already identified and ready for playback without requiring guessing or repeated adjustments.

AI summary
A transcription method, apparatus and computer program product are provided to permit a transcripted text report to be efficiently reviewed. In the context of a method, an audio file and a transcripted text report corresponding to the audio file may be received. For each of a plurality of positions within the transcripted text report, the method correlates the respective position within the transcripted text report with a corresponding position within the audio file. The method also augments the transcripted text report to include a plurality of selectable elements. Each selectable element is associated with a respective position within the transcripted text report. The selectable elements are responsive to user actuation in order to cause the audio file to move to the corresponding position. A corresponding apparatus and computer program product are also provided.
