Location-Based Conversational Understanding System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speech recognition systems lack the ability to leverage environmental contexts and user-specific data to improve query accuracy and results, particularly in noisy or location-specific scenarios.
Innovation Solution
A location-based conversational understanding system that analyzes and adapts to acoustic and environmental characteristics of a user's location, using a combination of acoustic models, Hidden Markov Models, and semantic models to filter out irrelevant noise and improve speech-to-text conversion accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional speech recognition systems process queries without environmental context, then the system complexity remains low, but the query accuracy and noise filtering capability deteriorate
Solution Approach 1:
The system performs preliminary actions by pre-processing acoustic signals to extract environmental characteristics and noise profiles before formal speech recognition. Environmental context data is gathered and stored in advance, allowing the speech recognition system to leverage pre-analyzed context information rather than processing everything in real-time, thus improving accuracy without proportionally increasing complexity
Solution Approach 2:
The patent introduces environmental context data as an intermediary element between the acoustic signal and speech recognition processing. This intermediary layer analyzes and characterizes the environment (noise profiles, acoustic properties) separately, then feeds this processed information to assist the speech recognition system, improving accuracy while keeping the core speech recognition module relatively simple
2Measurement precision
If speech recognition systems use generic processing without location-specific adaptation, then the ease of operation is maintained, but the query accuracy in diverse locations deteriorates
Solution Approach 1:
The system applies local quality by tailoring speech recognition processing to specific environmental conditions and locations. Different locations have their own acoustic profiles, noise characteristics, and context data that are used to optimize recognition performance for that particular environment, rather than using a one-size-fits-all approach
Solution Approach 2:
The system changes processing parameters based on environmental context. Acoustic models, noise filtering thresholds, and recognition sensitivity are adjusted according to the detected environmental conditions and location-specific characteristics, allowing the system to adapt to diverse locations while maintaining ease of operation
3Reliability
If environmental context analysis is integrated into speech recognition, then noise filtering capability improves, but the processing time and computational load increase
Solution Approach 1:
Environmental context analysis is performed in advance and stored for later use. Noise profiles, acoustic characteristics, and environmental data are pre-processed and cached, so that during actual speech recognition, the system can quickly retrieve and apply pre-analyzed context information rather than performing full environmental analysis in real-time
Solution Approach 2:
The system applies partial environmental context analysis based on the specific needs of each query and situation. Not all environmental factors are analyzed to the same depth for every speech query - the system selectively applies context information appropriate to the current situation, reducing unnecessary processing while maintaining effective noise filtering where needed
Data Source
AI summary
Location-based conversational understanding may be provided. Upon receiving a query from a user, an environmental context associated with the query may be generated. The query may be interpreted according to the environmental context. The interpreted query may be executed and at least one result associated with the query may be provided to the user.
