AUDIO DATA PROCESSING METHOD AND ELECTRONIC DEVICE SUPPORTING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18466318 titled 'AUDIO DATA PROCESSING METHOD AND ELECTRONIC DEVICE SUPPORTING SAME
Simplified Explanation
An electronic device is described in this patent application. It includes a wireless communication circuit, a microphone, an audio circuit, a processor, and a memory.
- The device is capable of executing a designated application.
- When the application is executed, the device sends a trigger signal to the audio circuit.
- The trigger signal is also transmitted to an external electronic device through the wireless communication circuit.
- The device then captures a response signal from the external electronic device using the microphone.
- By comparing the trigger signal with the response signal, the device calculates a path delay time using the audio circuit.
- Finally, the device performs an echo canceling operation based on the calculated path delay time.
Potential Applications
- This technology can be used in telecommunication devices to improve call quality by canceling echo.
- It can be utilized in voice-controlled devices to enhance voice recognition accuracy.
- The technology can be applied in conference systems to eliminate echo during remote meetings.
Problems Solved
- Echo is a common issue in telecommunication devices, which can degrade call quality and cause inconvenience to users.
- Accurate voice recognition is crucial for voice-controlled devices, and echo can interfere with the recognition process.
- Echo during remote meetings can disrupt communication and make it difficult for participants to understand each other.
Benefits
- The device can effectively cancel echo by calculating and compensating for the path delay time.
- Improved call quality leads to better user experience and clearer communication.
- Accurate voice recognition enhances the performance of voice-controlled devices.
- Eliminating echo in conference systems improves the overall meeting experience and productivity.
Original Abstract Submitted
An electronic device comprising a wireless communication circuit, a microphone, an audio circuit, a processor, and a memory operatively connected to the processor are provided. When a designated application is executed, the electronic device transmits a trigger signal to the audio circuit, transmits the trigger signal to an external electronic device through the wireless communication circuit, acquires a response signal corresponding to the trigger signal by using the microphone from the external electronic device, calculates a path delay time by comparing the trigger signal with the response signal by using the audio circuit, and performs an echo canceling operation based on the path delay time.
