Dual-Device Voice Wake-Up for Cleaning Robot Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice control methods for devices, such as cleaning devices, suffer from low sensitivity due to the inability to accurately pick up voice control instructions, often due to environmental factors like noise or blockages.
Innovation Solution
A voice control method and apparatus that acquire voice features from both the cleaning device and the base station to determine which device should be woken up for accurate voice instruction recognition, enhancing the sensitivity of voice control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice control is implemented using only the cleaning device's voice module, then the device structure remains simple, but voice control sensitivity is low due to environmental noise and blockages
Solution Approach 1:
The base station acts as an intermediary device that receives voice instructions when the cleaning device cannot pick them up. The base station has its own voice module and can process voice commands independently, then relay them to the cleaning device. This mediator approach solves the problem of voice control failure in noisy or blocked environments without requiring the cleaning device itself to have enhanced voice pickup capabilities.
Solution Approach 2:
The base station is designed with multi-functionality: it serves as both a charging station and a voice control receiver. By giving the base station the capability to receive and process voice instructions, the system achieves universal voice control functionality that works regardless of the cleaning device's position or environmental conditions.
2Measurement precision
If the base station is equipped with a voice module to improve voice pickup, then voice control accuracy improves, but the base station complexity and cost increase
Solution Approach 1:
The voice control function is segmented between two devices: the cleaning device and the base station. Each device has its own voice module, allowing them to independently pick up voice instructions. This segmentation distributes the functional burden and allows each component to be optimized for its specific role without requiring either device to be overly complex.
3Reliability
If multiple devices are used for voice recognition, then voice control reliability improves, but the system complexity increases
Solution Approach 1:
The system implements feedback mechanisms where the cleaning device and base station continuously monitor their voice pickup status. When the cleaning device detects it cannot pick up voice instructions (due to noise or blockage), it feedbacks this status and the base station takes over. This feedback loop ensures seamless transition and maintains voice control availability without requiring complex manual intervention.
Data Source
AI summary
A voice control method and apparatus for a device, a storage medium, and an electronic apparatus are provided. The method includes: acquiring a first voice feature of first voice data collected by a cleaning device, where the first voice data correspond to a first wake-up instruction sent by a use object, and the first wake-up instruction is used to wake up at least one of the cleaning device and a base station; acquiring a second voice feature of second voice data collected by the base station, where the second voice data correspond to the first wake-up instruction; and selecting a first device to be woken up from the cleaning device and the base station according to the first and second voice features, and waking up the first device, where the first device in a wake-up state is configured to respond to a voice instruction sent by the use object.
