Voice Output Unit Automatic Waking Word Trigger for Input-Output Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice recognition systems require users to utter a waking word or press a startup button to initiate the input-output device and voice operation service, limiting functionality unless explicit user input is provided.
Innovation Solution
An information processing apparatus that includes a voice output unit to output a waking word automatically, a reception unit to receive user startup operations, and a control unit to initiate the input-output device startup based on user input, allowing the system to start without explicit voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the input-output device requires explicit user commands (waking word or startup button press) to initiate operation, then the system maintains reliable control over when to activate voice recognition, but the ease of operation deteriorates as users must perform additional startup actions
Solution Approach 1:
The information processing apparatus automatically outputs the waking word to the input-output device without requiring explicit user commands to initiate startup. The control unit autonomously triggers the voice output unit to speak the waking word, enabling the system to start itself rather than requiring user-initiated voice commands or button presses.
Solution Approach 2:
The system performs preliminary actions by automatically outputting the waking word before the user needs to use voice recognition. The control unit is configured to trigger the voice output unit to speak the waking word in advance, so that when the user approaches the device, the waking word is already spoken and the system is ready for voice commands without requiring the user to first press a button or wait for manual activation.
2Productivity
If the voice operation service requires explicit user commands to start, then the service maintains clear activation triggers, but the productivity deteriorates as users experience delays before voice recognition becomes available
Solution Approach 1:
The information processing apparatus performs preliminary startup actions automatically. The control unit triggers the voice output unit to speak the waking word before the user issues voice commands, eliminating the need for users to wait for manual activation. This preliminary automatic startup reduces the time loss between when a user needs voice recognition and when it becomes available.
3Ease of operation
If the system automatically outputs the waking word without user commands, then the ease of operation improves as users don't need to press buttons or wait for manual startup, but the device complexity increases due to additional automatic control mechanisms
Solution Approach 1:
The information processing apparatus implements self-service functionality where the control unit automatically manages the startup process. The control unit triggers the voice output unit to speak the waking word without requiring explicit user commands, enabling the system to initiate itself and eliminating the need for users to press buttons or wait for manual activation.
Solution Approach 2:
The control unit serves multiple functions: it manages the automatic triggering of the voice output unit, coordinates the startup sequence, and prepares the voice recognition system for operation. By consolidating these functions into a single control unit, the system achieves multi-functionality that reduces overall system complexity despite adding automatic startup capabilities.

AI summary
An information processing apparatus communicating with an input-output device that receives an input voice, outputs voice data corresponding to the input voice, and communicates with a server that analyzes the output voice data. The information processing apparatus further includes a voice output unit configured to output a voice, a reception unit configured to receive a user operation for starting the input-output device, and a control unit configured to perform control to, in response to the user operation received by the reception unit, cause the voice output unit to output a waking word for starting the input-output device.
