Solution Overview

Problem

Current voice translation technologies face challenges in accurately translating voice inputs due to differences in language expressions and sentence structures, leading to variations in recognition and translation outcomes, even for similar or identical meanings.

Innovation Solution

An automated interpretation method that encodes a voice signal in a first language to generate a feature vector, decodes it to produce a sentence in the first language, encodes this sentence to generate a feature vector for a second language, decodes it to produce a sentence in the second language, and selects a final translation from a candidate list based on various feature vectors and sentences, enhancing translation accuracy by considering multiple candidate sentences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If direct translation method is used, then translation speed is improved, but translation accuracy deteriorates

Engineering Contradiction:
Improvetranslation speedVSAvoidtranslation accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by generating multiple candidate translations before selecting the final translation. The translation engine produces several candidate sentences, which are then evaluated using similarity calculations against the original voice signal and intermediate representations. This preliminary generation of multiple options allows the system to maintain high speed while ensuring accuracy through subsequent selection based on similarity metrics.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by calculating similarity between the original voice signal, intermediate voice/sentence representations, and candidate translations. The similarity calculation results feed back into the selection process, allowing the system to iteratively evaluate and choose the most accurate translation from multiple candidates, thereby resolving the contradiction between speed and accuracy.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If multiple candidate sentences are considered, then translation accuracy is improved, but processing complexity increases

Engineering Contradiction:
Improvetranslation accuracyVSAvoidprocessing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system introduces intermediary representations (encoded voice features and decoded sentence features) as mediators between the original voice signal and candidate translations. These intermediaries serve as reference points for similarity calculation, enabling the system to evaluate multiple candidates efficiently without excessive complexity. The intermediaries act as a bridge that simplifies the comparison process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes parameters by transforming the voice signal into different feature space representations (encoded voice features, decoded sentence features) and evaluating candidate translations based on similarity in this transformed space. This parameter transformation allows for efficient comparison and selection among multiple candidates while managing processing complexity through mathematical operations in feature space.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If voice signal encoding and decoding is performed multiple times, then translation robustness is improved, but computational cost increases

Engineering Contradiction:
Improvetranslation robustnessVSAvoidcomputational cost
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary encoding of the voice signal into feature representations before the translation process. These pre-encoded features are then reused multiple times during candidate evaluation and similarity calculations, avoiding the need to re-encode the voice signal from scratch. This preliminary action reduces computational cost while maintaining robustness through multiple uses of the encoded features.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates copies of the encoded voice features and decoded sentence features, which are then used as references for evaluating multiple candidate translations. Instead of re-processing the original voice signal multiple times, the system copies and reuses the intermediate feature representations, significantly reducing computational cost while maintaining translation robustness through multiple evaluation points.

Inventive Principle:
Principle #26Copying
