Mixed Language Translation System Using Segmentation and Entity Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Speech recognition and translation systems face challenges when handling mixed multilingual communication, as they are often designed to assume input is in a single language and struggle to accurately translate when foreign language elements are present, leading to potential misinterpretation or failure in translation.
Innovation Solution
The implementation of language detection and processing techniques that isolate and preserve named entities from both the primary and secondary languages during the translation process, allowing for accurate translation of primary language content while maintaining or translating secondary language elements as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If speech recognition and translation systems assume input is in a single language, then the translation accuracy for pure monolingual input is maintained, but the system fails or misinterprets when foreign language elements are present in mixed multilingual communication
Solution Approach 1:
The system segments the input speech stream into distinct language segments using language detection. Each segment is identified as belonging to a specific language (primary language or foreign language), allowing the system to process them differently. This segmentation enables the system to maintain high translation accuracy for the primary language while appropriately handling foreign language elements, thus resolving the contradiction between adaptability to mixed languages and reliability of translation accuracy.
Solution Approach 2:
The system applies different processing qualities to different parts of the input. Foreign language segments are preserved as-is (local quality: no translation), while primary language segments undergo full translation processing. This localized differentiation allows the system to adapt to multilingual input without compromising the translation accuracy of the target language content.
2Productivity
If the system translates all input text, then complete translation coverage is achieved, but foreign language named entities and proper nouns are incorrectly translated or lost
Solution Approach 1:
The system extracts foreign language named entities and proper nouns from the translation process. After language detection identifies foreign language segments, the system extracts these elements and preserves them in their original form rather than translating them. This extraction prevents loss of information about foreign language named entities while maintaining translation coverage for the primary language content.
Solution Approach 2:
Instead of translating everything and then attempting to preserve foreign elements, the system inverts the approach by first identifying and preserving foreign language elements, then translating only the remaining primary language content. This inversion ensures that foreign named entities are not incorrectly translated while maintaining complete translation coverage for appropriate content.
3Adaptability or versatility
If the system uses a database trained on two different languages, then the system can handle basic multilingual translation, but it cannot accurately process mixed language utterances with foreign language elements embedded in primary language speech
Solution Approach 1:
The system dynamically adjusts its processing mode based on real-time language detection. Rather than using a static database trained on fixed language pairs, the system continuously detects the language of each speech segment and adapts its translation behavior accordingly. This dynamic approach enables accurate processing of mixed language utterances by switching between translation and preservation modes as needed, improving both adaptability and measurement precision.
Data Source
AI summary
A translation between a source language and a target language is disclosed. The source language items are divided, with primary and secondary source language items or named entities being identified, where the primary and secondary source languages being different from each other and from the target language. The entities in the second source language are translated in a different way. For example, they may be copied into the target language, or translated in a special way that is based on their meaning, e.g, into a term that has a more descriptive meaning in the target language.
