Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current speech recognition systems lack convenience in executing voice commands based on the state of the electronic device, such as silent mode or user context, leading to inconsistent user experiences.

Innovation Solution

An electronic device equipped with a microphone and processor that judges the device's state upon recognizing voice commands, executing different processes based on whether the device is in a predetermined state, such as silent mode, or not, allowing for tailored responses like audio output or display-only interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If speech recognition processing is performed without considering device state, then speech recognition function is provided, but convenience is reduced due to inappropriate process execution

Engineering Contradiction:

Improveconvenience of speech recognitionVSAvoidappropriateness of process execution

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The processor performs preliminary judgment on the device state (silent mode determination) before executing the speech recognition process. This preliminary action ensures that the appropriate process is selected based on the current device state, preventing inappropriate process execution and improving user convenience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts its behavior based on the detected device state. When silent mode is detected, the processor executes a different process compared to when silent mode is not active. This dynamic adaptation allows the speech recognition function to respond appropriately to different operational contexts.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If different processes are executed based on device state, then user convenience is improved, but device complexity increases

Engineering Contradiction:

Improveuser convenienceVSAvoidcomplexity of process selection

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system changes the execution parameter (process type) based on the device state parameter. By determining whether silent mode is active and selecting processes accordingly, the system achieves state-dependent behavior without requiring complex architectural changes. This parameter-based approach simplifies the overall system design.

Inventive Principle:

Principle #35Parameter changes

AI summary

An electronic device includes a microphone configured to receive input of speech and a processor configured to recognize the speech inputted to the microphone. The processor judges whether the state of the electronic device is a predetermined state when a voice command is recognized based on the speech inputted to the microphone. The processor executes a first process corresponding to the voice command when the processor judges that the state of the electronic device is the predetermined state and executes a second process corresponding to the voice command when the processor judges that the state of the electronic device is not the predetermined state. This electronic device improves the convenience of speech recognition.
