Cross-Device Call Audio Routing for Better Voice Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing call methods in terminal devices result in poor audio quality due to the use of different devices for audio collection and playback, leading to suboptimal call effects.
Innovation Solution
A method that allows users to select different devices for audio data collection and playback, utilizing a combination of terminal and external devices for improved audio processing, including synthesis processing to align audio data and enhance call quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device uses the same device for both audio collection and playback, then the device configuration is simple, but the call effect is poor
Solution Approach 1:
The patent divides the audio processing function into two separate devices: one device (first device) is dedicated to audio collection, while another device (second device) is dedicated to audio playback. This segmentation allows each device to be optimized for its specific function, thereby improving overall call quality without requiring a single complex device to perform both functions simultaneously.
2Reliability
If the terminal device uses different devices for audio collection and playback, then the call effect is improved, but the device selection and configuration becomes complex
Solution Approach 1:
The patent performs preliminary actions by pre-establishing connection relationships between multiple devices and pre-configuring their audio collection and playback capabilities. Before the actual call, the system has already determined which devices are available and suitable for audio collection and playback, so during the call, the terminal device can directly select from pre-validated device combinations, simplifying the user's decision-making process.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal device provides information about available devices and their audio capabilities to the user interface. This allows users to see what devices are available for audio collection and playback, making the selection process more transparent and easier to manage, thereby improving ease of operation while maintaining improved call effects.

AI summary
Embodiments of this application provide a call method and a call apparatus, applied to the field of terminal technologies. The method includes: A terminal device collects audio data by using a first device, and sends the audio data collected by the first device to a call peer end, where the first device includes one or more of a plurality of devices, and the plurality of devices include the terminal device and an external device that has established a connection relationship with the terminal device; and the terminal device receives audio data from the call peer end, and plays the audio data from the call peer end by using a second device, where the second device includes one or more of the plurality of devices, and at least one device in the first device and at least one device in the second device are different devices in the plurality of devices. According to the technical solutions provided in this application, audio data may be collected and audio data may be played by using different devices, so that call effect can be improved.
