Audio Triggered Command Execution via Silent Period Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current speech recognition systems lack the ability to effectively execute commands based on audio triggers, such as detecting specific sounds and responding with actions when those sounds are not followed by others within a certain timeframe, limiting their functionality in scenarios like home automation and user behavior correction.
Innovation Solution
A system that recognizes a first event through audio signals, analyzes further input to detect a second event, and executes a command if the second event is not detected within a threshold period, using a combination of audio detection devices, sound recognition models, and text-to-speech processing to provide responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If speech recognition systems only process continuous speech commands, then the system structure remains simple, but the system cannot detect specific sounds and execute commands based on audio triggers
Solution Approach 1:
The system segments audio processing into distinct functional modules: audio input reception, sound recognition model processing, command detection, threshold evaluation, and text-to-speech output. This modular segmentation enables the system to handle both continuous speech commands and audio trigger events with different processing logic, thereby improving adaptability while maintaining manageable system complexity through organized functional separation
Solution Approach 2:
The system is designed with multi-functionality to handle multiple types of audio inputs: continuous speech commands, specific sound triggers, and silent period detection. The same processing framework accommodates different command types (speech-based and audio-triggered) and response modes (immediate execution vs. delayed execution based on silence threshold), making the system universally applicable to various audio interaction scenarios without requiring separate dedicated systems
2Speed
If the system executes commands immediately upon detecting a sound trigger, then the response time is fast, but it cannot distinguish between intentional triggers and background noise
Solution Approach 1:
The system performs preliminary sound recognition and classification before command execution. The sound recognition model pre-processes audio triggers to identify specific sound patterns, and the system pre-evaluates whether detected sounds match configured trigger criteria before initiating command execution. This preliminary filtering action prevents false triggers from background noise while maintaining fast response for valid triggers
Solution Approach 2:
The system incorporates feedback mechanisms where the sound recognition model continuously monitors audio input and provides classification feedback to the command detection logic. The system compares detected sounds against configured trigger patterns and provides feedback on match confidence, enabling reliable distinction between intentional triggers and background noise while maintaining rapid response capability for confirmed triggers
3Adaptability or versatility
If the system monitors for silent periods to execute commands, then it can detect when actions are not completed, but it increases the complexity of audio signal analysis
Solution Approach 1:
The system applies partial monitoring by focusing audio analysis only on specific frequency ranges and sound patterns relevant to configured triggers, rather than analyzing the entire audio spectrum continuously. The silent period detection is activated selectively based on trigger detection rather than running continuously, reducing overall analysis complexity while maintaining the capability to detect incomplete actions and provide behavior correction feedback
Data Source
AI summary
A system is configured to execute audio-initiated commands. The system detects audio and determines if a first sound is included in the audio. The system then processes further incoming audio to detect a second sound. If the second sound is not detected within a time threshold, the system executes a command. The command may include delivering a message, outputting audio corresponding to synthesized speech, or some other executable command.
