Voice Command Unit Automatic Speech Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses require manual operations to start and end voice input, leading to potential continuous voice input issues and noise contamination, as they rely on user-initiated commands rather than automatically detecting speech output.
Innovation Solution
The apparatus includes a voice command unit that automatically detects speech output by analyzing voice information and image data from a microphone and camera, determining speech periods based on sound volume and image recognition, allowing for seamless voice command execution without additional user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operations are required to start and end voice input, then user control over voice input timing is improved, but ease of operation deteriorates due to additional user interactions needed
Solution Approach 1:
The voice input system automatically detects speech periods and executes voice commands without requiring manual start/stop operations from the user. The system serves itself by autonomously identifying when speech occurs and processing the voice input, eliminating the need for additional user interactions to control voice input timing
Solution Approach 2:
The system performs preliminary detection of speech periods before executing voice commands. By detecting the presence and duration of speech in advance, the system prepares to process voice input automatically, enabling seamless operation without waiting for manual user commands
2Reliability
If voice input continues without automatic detection, then ease of operation improves by allowing continuous input, but noise contamination increases due to inclusion of non-speech sounds
Solution Approach 1:
The system continuously monitors voice information and provides feedback to determine whether speech is currently occurring. Based on this feedback, the system dynamically adjusts voice input processing, activating only during detected speech periods and remaining inactive during non-speech periods, thereby maintaining high accuracy while excluding noise
Solution Approach 2:
The voice input system operates periodically based on detected speech periods rather than continuously. It activates during speech periods and deactivates during non-speech periods, creating a rhythmic on/off pattern that ensures voice input is captured only when relevant speech occurs, preventing noise contamination
3Productivity
If automatic speech detection is implemented, then productivity improves by reducing user interactions, but device complexity increases due to additional detection mechanisms
Solution Approach 1:
The voice recognition unit serves multiple functions: it both recognizes voice commands and detects speech periods. By making this component multi-functional, the system achieves automatic speech detection without adding separate dedicated detection hardware, thereby improving productivity while limiting the increase in device complexity
Solution Approach 2:
The patent combines the voice recognition function with the speech period detection function into a unified process. The same voice recognition unit that processes commands also identifies when speech occurs, merging two functions into one integrated system that improves efficiency without proportionally increasing complexity
Data Source
AI summary
An information processing apparatus includes an acquiring unit, a detecting unit, and a voice command unit. The acquiring unit acquires voice information of a speaker. The detecting unit detects operation related to speech by the speaker. The voice command unit performs a voice command in accordance with the voice information acquired by the acquiring unit after the detecting unit detects the operation.
