Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If professional recording equipment and indoor recording conditions are used, then voice intelligibility and audio quality are improved, but device complexity and recording conditions requirements increase
Solution Approach 1:
The patent replaces physical acoustic treatment and professional recording equipment with signal processing algorithms. The voice enhancement is achieved through transcript-based processing that works on recorded audio signals, substituting the need for controlled acoustic environments and expensive equipment with computational methods that can run on standard devices.
Solution Approach 2:
The system changes the parameters of the audio signal through transcript-based enhancement. By using the transcript information to guide signal processing operations, the system modifies spectral characteristics, temporal features, and amplitude parameters of the audio signal to improve voice intelligibility without requiring changes to the physical recording environment.
2Measurement precision
If professional recording conditions are required, then audio quality is improved, but ease of operation and accessibility decrease
Solution Approach 1:
The system performs automatic transcript-based voice enhancement without requiring user intervention for manual audio processing. The transcript is automatically generated or provided, and the enhancement process is automatically applied to the audio signal, making the system easy to operate and accessible to non-professional users.
Solution Approach 2:
The voice enhancement processing is performed as a post-processing step after recording, allowing users to capture audio in casual settings and then enhance it automatically. This preliminary enhancement action removes the need for users to understand or control complex recording parameters during the actual recording process.
3Measurement precision
If transcript-based voice enhancement is implemented, then voice intelligibility is improved without professional equipment, but processing time and computational requirements increase
Solution Approach 1:
The transcript is generated or obtained before the voice enhancement processing begins. This preliminary preparation of the transcript information allows the enhancement algorithm to work efficiently by having the reference data ready, reducing the overall processing time compared to generating the transcript during the enhancement process.
