Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional natural language understanding engines in contact centers struggle with accurately recognizing specific subject matter words, such as names with regional origins or industry-specific terminology, leading to incorrect resource allocation and poor user experience.

Innovation Solution

A contact center apparatus equipped with a natural language understanding engine and a language reinforcement engine, where the latter utilizes a phonetic model trained on subject matter terms to refine phonetic text generated by the former, ensuring accurate word recognition and resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a general purpose language model is used for speech-to-text conversion, then the system can handle general conversations, but it produces incorrect recognition for subject matter specific terms

Engineering Contradiction:

Improvegeneral conversation handlingVSAvoidword recognition accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system segments the language model processing into two distinct stages: first, a general purpose language model handles overall speech-to-text conversion, and second, a subject matter specific language model corrects and refines the recognition of domain-specific terms. This segmentation allows each model to specialize in its strength while working together to achieve both versatility and precision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The subject matter specific language model acts as an intermediary between the general purpose language model and the final text output. It receives the initial transcription, identifies subject matter specific terms, and applies corrections using domain-specific vocabulary and context, thereby mediating between general speech recognition and accurate domain-specific interpretation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If phonetic equivalence is used for text conversion, then the system can process speech input, but it creates misinterpretations of names and terminology

Engineering Contradiction:

Improvespeech input processingVSAvoidtext interpretation accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary phonetic transcription using the general purpose language model to convert speech to text, then applies subject matter specific language modeling in a subsequent step to correct phonetic misinterpretations before final output. This preliminary action allows speech processing to proceed efficiently while enabling later correction of accuracy issues.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The subject matter specific language model provides feedback correction to the phonetic transcription. By comparing the initial transcription against domain-specific vocabulary and context, it identifies and corrects phonetic misinterpretations, creating a feedback loop that improves accuracy without requiring complete redesign of the speech processing pipeline.

Inventive Principle:

Principle #23Feedback

3Device complexity

If a general purpose natural language understanding engine is used, then the system architecture remains simple, but user experience deteriorates due to incorrect resource allocation

Engineering Contradiction:

Improvesystem architectureVSAvoidresource allocation accuracy

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The natural language understanding engine is segmented into two processing layers: a general purpose layer that maintains simple architecture and handles overall speech-to-text conversion, and a subject matter specific layer that adds targeted correction capabilities. This segmentation improves resource allocation accuracy without requiring complete system redesign.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The dual-language model system achieves multi-functionality by combining general purpose speech recognition with subject matter specific term correction in a single integrated pipeline. This allows the system to handle both general conversations and domain-specific terminology accurately, improving reliability across different use cases without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

In a contact center apparatus, a method for generating recognized text based upon verbal data, comprising: receiving verbal data from a user; applying a natural language understanding engine the verbal data to generate phonetic representation text, the phonetic representation text configured as a phonetic representation of the verbal data; applying a language reinforcement engine to the phonetic representation text to generate recognized text, the recognized text identifying a word associated with the verbal data; and directing the user to a contact center resource based upon the recognized text.
