Audio Playback Delay Mitigation via Waveform Modification Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems experience delays in receiving and processing audio waveforms, leading to unintelligible or inaccurate sound production, characterized by 'choppy' or 'skipping' issues, which degrade the quality of sound and affect worker acceptance in speech-directed work environments.
Innovation Solution
An apparatus and method that utilize transceiving circuitry to receive audio streams, with processing circuitry analyzing the waveform to identify modification segments where sound production can be adjusted to mitigate delays, such as pausing or extending sound at natural language pauses or quasi-stationary segments, ensuring smooth audio playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If audio playback waits for complete reception of audio waveform into buffer, then sound production accuracy is improved, but playback time is delayed
Solution Approach 1:
The system performs preliminary actions by buffering audio waveforms in advance before playback is needed. The audio waveform is received and stored in a buffer memory prior to the actual playback moment, allowing the playback to start without waiting for complete data reception. This resolves the contradiction by preparing the audio data ahead of time.
Solution Approach 2:
The system dynamically adjusts the buffering strategy based on network conditions and playback requirements. The buffer management is flexible, allowing the system to optimize between waiting for complete audio data versus playing back immediately. This dynamic approach resolves the contradiction by adapting the timing strategy to current system state.
2Speed
If audio playback starts before subsequent audio stream is fully received, then playback speed is improved, but sound production quality deteriorates due to choppy or skipping issues
Solution Approach 1:
The system buffers audio waveforms in advance so that playback can start before the entire audio stream is received. This preliminary buffering action enables early playback while maintaining quality by ensuring sufficient buffer capacity is prepared beforehand.
Solution Approach 2:
The system monitors buffer status and playback progress to provide feedback control. When the buffer is depleted or playback quality degrades, the system adjusts buffering behavior accordingly. This feedback mechanism ensures playback quality is maintained while allowing early start.
3Manufacturing precision
If the system waits for complete audio waveform reception before playback, then sound intelligibility is improved, but worker acceptance decreases due to delays in audio feedback
Solution Approach 1:
The system performs preliminary buffering of audio waveforms so that playback can begin before complete reception. This preliminary action maintains intelligibility by ensuring adequate buffer capacity is prepared while reducing perceived delay for the worker.
Solution Approach 2:
The system manages its own buffering and playback timing autonomously without requiring worker intervention. The self-service buffer management optimizes the balance between intelligibility and responsiveness, improving worker acceptance while maintaining quality.

AI summary
A communication component modifies production of an audio waveform at determined modification segments to thereby mitigate the effects of a delay in processing and/or receiving a subsequent audio waveform. The audio waveform and/or data associated with the audio waveform are analyzed to identify the modification segments based on characteristics of the audio waveform and/or data associated therewith. The modification segments show where the production of the audio waveform may be modified without substantially affecting the clarity of the sound or audio. In one embodiment, the invention modifies the sound production at the identified modification segments to extend production time and thereby mitigate the effects of delay in receiving and/or processing a subsequent audio waveform for production.
