Solution Overview

Problem

Contact centers face challenges in efficiently searching and analyzing large volumes of audio conversations due to the tedious and time-consuming nature of traditional text searches, which often fail to capture nuanced queries and require extensive human review.

Innovation Solution

The Engagement Intelligence Platform (EIP) provides a flexible search tool that analyzes audio conversations by identifying states and information associated with each state, enabling transition-driven searches and allowing users to tag and annotate conversations using a customizable annotator UI.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If human reviewers listen to conversations manually, then search accuracy is improved, but time consumption and cost increase significantly

Engineering Contradiction:
Improvesearch accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual human review of audio conversations with an automated machine-learning-based system. The EIP transcribes audio to text and uses ML models to automatically identify states, entities, and relationships, eliminating the need for human reviewers to listen to entire conversations while maintaining high search accuracy through intelligent automated analysis.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a textual copy (transcript) of the audio conversation and analyzes this copy using machine learning models. This copying approach allows the system to process conversations quickly without requiring human review of the original audio, significantly reducing time consumption while maintaining search precision through the intelligent processing of the text representation.

Inventive Principle:
Principle #26Copying

2Productivity

If text searches are performed on transcribed conversations, then search speed is improved, but search accuracy for nuanced queries deteriorates

Engineering Contradiction:
Improvesearch speedVSAvoidsearch accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent transforms the search approach by changing from simple text keyword matching to a multi-parameter analysis system. The EIP identifies and extracts multiple parameters including states, entities, relationships, and contextual information using machine learning models, enabling both fast search execution and high accuracy for nuanced queries through sophisticated parameter-based filtering and matching.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system segments the conversation analysis into distinct components: transcribing audio to text, identifying states, extracting entities, and establishing relationships. This segmentation allows each component to be optimized independently, with the text transcription providing speed and the ML-based state/entity/relationship analysis providing precision, achieving both fast and accurate search results.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If traditional text searches are used on conversations, then system complexity is reduced, but ability to capture nuanced information deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoidnuanced information capture
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent introduces machine learning models as intermediary components between the raw audio/text and the search queries. These ML models act as mediators that automatically interpret nuanced information, extract meaningful patterns, and prepare data structures that can answer complex queries, enabling the system to capture nuanced information without requiring overly complex search interfaces or manual processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary analysis by automatically transcribing audio to text and pre-processing the data to identify states, entities, and relationships before actual search queries are executed. This preliminary action prepares the conversation data in an optimized format that enables both simple and nuanced searches to work effectively, reducing the need for complex search mechanisms while maintaining high information capture capability.

Inventive Principle:
Principle #10Preliminary action

AI summary

Methods, systems, and computer programs are presented for searching and labeling the content of voice conversations. An Engagement Intelligence Platform (EIP) analyzes conversation transcripts to find states and information for each of the states (e.g., interest rate quoted and value of the interest rate). An annotator User Interface (IU) is provided for performing queries, such as, “Find calls were the agent asked the customer for their name and the customer did not answer;”“Find calls where the customer objected after the interest rate for the loan was quoted, “Find calls where the agent asked for consent for recording the call, but no customer confirmation was received.” The EIP analyzes the conversation and labels (e.g., “tags”) the text where the conversation associated with the label took place, such as, “An interest rate was provided.” The labels are customizable, so each client can define its own labels based on business needs.
