Voice Detection System for Image Processing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice operation systems in image processing devices face issues with misrecognition of voice instructions to stop jobs, leading to unnecessary job interruptions and decreased productivity, as the timing for accepting voice instructions to stop processing is not adaptable to the specific nature and progress of different job types.
Innovation Solution
An image processing device with a controller and voice detection system that identifies predetermined target voices during specific setting periods defined for various job types, allowing for precise stopping of job execution based on the job's progress stages and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice instruction acceptance is continuous during job execution, then user can stop operation when noticing error, but misrecognition of voice increases causing useless stops
Solution Approach 1:
The patent applies dynamics by making the voice instruction acceptance period variable rather than fixed. The acceptance period dynamically adjusts based on the job execution stage, being longer at the beginning when errors are more likely and shorter or closed later when errors are less likely to be noticed, thus adapting to the changing reliability needs during job execution
Solution Approach 2:
The patent changes the parameter of voice instruction acceptance timing based on job type and execution progress. Different job types (copy, print, fax) have different acceptance periods defined, and the system selects appropriate parameters dynamically, resolving the contradiction between continuous acceptance and misrecognition
2Ease of operation
If voice instruction acceptance period is fixed for all job types, then system operation is simple, but user cannot stop operation at appropriate timing for specific job types
Solution Approach 1:
The patent segments the voice instruction acceptance period into job-type-specific periods. Instead of a single unified acceptance period, the system divides acceptance timing rules into separate segments for different job types (copy jobs, print jobs, fax jobs), allowing each segment to be optimized independently while maintaining overall system simplicity through automated selection
Solution Approach 2:
The patent creates a universal voice instruction processing system that handles multiple job types through a single integrated mechanism. The same voice recognition system serves multiple functions by adapting its acceptance period based on the current job type, eliminating the need for separate voice processing systems for each job type

AI summary
An image processing device capable of executing a plurality of jobs that differ in kind, the image processing device includes: a controller that controls execution of an input job; and a detection part that, on the basis of a voice detected by a voice detector, detects that any of a plurality of predetermined target voices has been emitted, wherein in a case where it is detected that the target voice has been emitted during a target setting period corresponding to a job that is being executed, among setting periods that are defined beforehand according to kinds of jobs respectively, the controller stops the execution of the job.
