Voice Interaction System Handling Ambiguous User Speech
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice interaction systems face difficulties in responding appropriately to ambiguous user speech, lacking clear intention, which can lead to unpleasant interactions.
Innovation Solution
An information output system comprising a speech acquisition unit, recognition processing unit, and output processing unit that acquires user speech, recognizes its content, outputs questions, and determines guidance information based on the user's positive degree derived from their responses, providing tailored guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system responds to ambiguous user speech using pre-stored interaction scenarios, then the system can provide some level of response, but the response accuracy and user satisfaction deteriorate when user intention is unclear
Solution Approach 1:
The system performs preliminary actions by storing multiple interaction scenarios in advance and preparing clarification questions before being explicitly asked. When ambiguous speech is detected, the system has pre-prepared guidance information and follow-up questions ready to guide the user toward clarifying their intention, rather than responding directly to the ambiguous input.
Solution Approach 2:
The system implements feedback by outputting clarification questions to users when ambiguous speech is detected. The system waits for user responses to these questions, uses the responses to update understanding of user intention, and iteratively refines the response based on this feedback loop until user intention becomes clear.
2Measurement precision
If the system asks clarification questions to resolve ambiguous speech, then user intention recognition accuracy improves, but interaction time and complexity increase
Solution Approach 1:
The system applies partial action by selectively asking clarification questions only when ambiguous speech is detected, rather than asking questions in all interactions. The system balances between direct response and clarification by evaluating speech ambiguity first, thus avoiding unnecessary interaction delays while maintaining accuracy when needed.
3Adaptability or versatility
If the system stores multiple interaction scenarios in advance, then response capability to various user inputs improves, but system complexity and memory requirements increase
Solution Approach 1:
The system achieves universality by designing interaction scenarios that can handle multiple types of ambiguous speech through common clarification question templates. Rather than creating entirely separate handling mechanisms for each ambiguous input type, the system uses universal clarification procedures that adapt to different contexts, reducing overall system complexity while maintaining broad adaptability.

AI summary
An information output system includes a speech acquisition unit configured to acquire a speech of a user, a recognition processing unit configured to recognize the content of the acquired speech of the user, and an output processing unit configured to output a question to the user and to perform processing for outputting a response to the content of the speech of the user who has answered the question. The output processing unit is configured to derive a user's positive degree based on the content of the speech of the user who has answered the question and to determine guidance information to be output to the user based on the derived positive degree.
