Voice Interface Modality Selection for Information Delivery
Solution Overview
Problem
Conventional smart assistant devices face inefficiencies in delivering information via voice output, as users struggle to recognize and remember large amounts of information provided auditorily, leading to degraded efficiency in information delivery.
Innovation Solution
An electronic device equipped with a processor that determines whether the result of a voice command is visually or auditorily appropriate based on the information amount, and accordingly selects the output device as either a screen or speaker, optimizing information delivery by using the most suitable modality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the smart assistant device provides a considerable amount of information via voice output at a single given time, then the information delivery capacity is increased, but the user's ability to recognize and remember the information deteriorates
Solution Approach 1:
The patent segments information delivery into two distinct channels: voice output for concise auditory information and screen device output for detailed visual information. The processor divides the result information based on its nature, presenting key points verbally while directing users to screens for comprehensive data, thereby preventing information overload in the auditory channel while maintaining high information delivery capacity
Solution Approach 2:
The patent transitions from a single-dimensional voice-based information delivery to a multi-dimensional approach by incorporating both auditory (voice) and visual (screen) dimensions. This allows information to be delivered through appropriate channels based on the type and amount of information, with voice handling temporal/sequential data and screens handling spatial/complex data structures
2Device complexity
If the electronic device uses only voice output for all types of information, then the system complexity is reduced, but the ease of operation and user experience deteriorates due to information overload
Solution Approach 1:
The patent implements dynamic selection of output devices based on real-time analysis of information characteristics. The processor dynamically determines whether to use voice or screen output by evaluating the nature and amount of information, adjusting the information delivery modality adaptively rather than using a fixed approach, thereby optimizing user experience without requiring complex manual configuration
Solution Approach 2:
The patent creates complementary copies of information in different formats: voice provides a verbal copy of key information while screen devices display visual copies of detailed information. This allows users to receive concise auditory summaries while having access to comprehensive visual representations when needed, enhancing ease of operation through format-appropriate information presentation

AI summary
According to an embodiment of the disclosure, an electronic device may include a speaker, a microphone, a wireless communication circuit, and at least one processor connected to the speaker, the microphone, and the wireless communication circuit. The at least one processor may be configured to: in response to a user's voice command received through the microphone, perform a task corresponding to the voice command, based on an information amount contained in a result of the task, determine a type of the result to be visually appropriate or auditorily appropriate, and based on the type of the result, determine a device for providing the result as a screen device or a speaker.
