Speech Prompt Query for Smart Device Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart devices require high user dependency for speech interaction, leading to low probability of correct speech instruction input and uncontrolled situations due to the lack of real-time speech prompts during the interaction process.
Innovation Solution
A speech interactive method and device that detect user operations during application interface display, query and set applicable speech instructions, and provide prompts based on these instructions to facilitate real-time speech interaction, reducing user dependency and guiding users through available functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the smart device provides speech prompts only after user input, then the device complexity is reduced, but the user dependency increases and speech recognition failure probability increases
Solution Approach 1:
The system queries and displays applicable speech instructions before the user inputs speech, during the interface display process. This preliminary provision of speech prompts enables users to know what instructions are available before attempting speech input, reducing recognition failure probability without significantly increasing device complexity
Solution Approach 2:
The system provides real-time feedback by displaying speech prompts that are relevant to the current interface state. This feedback loop allows users to adjust their speech input based on the displayed prompts, improving speech recognition success rate while maintaining manageable device complexity
2Reliability
If the smart device provides comprehensive speech prompts in advance, then the speech recognition success rate improves, but the device complexity increases
Solution Approach 1:
Instead of providing all possible speech prompts uniformly, the system queries and displays only the speech instructions that are locally relevant to the current interface and application state. This selective provision of prompts improves recognition success rate for context-appropriate commands while avoiding the complexity of managing comprehensive prompt databases
Solution Approach 2:
The speech prompt system is segmented into application-specific instructions and system general instructions. The query process separately retrieves relevant prompts from different sources based on the current context, reducing the complexity of managing a single comprehensive prompt system while maintaining high recognition success rates
3Ease of operation
If the user must remember speech prompts in advance, then the ease of operation decreases, but the information processing load on the device decreases
Solution Approach 1:
The system automatically queries and displays the relevant speech instructions based on the current interface state, without requiring users to remember prompts in advance. This self-service approach improves ease of operation by providing context-relevant prompts automatically, while the information processing load is managed through selective querying based on interface context
Data Source
AI summary
The present disclosure provides a speech interactive method and device. The method includes: during a process of displaying an interface of an application, detecting a first user operation; in response to the first user operation, querying a speech instruction associated with the application based on the application containing the interface and querying a system general speech instruction; setting the speech instruction and the system general speech instruction as applicable speech instructions for the application; and providing a prompt based on the applicable speech instructions to perform a speech interaction.
