Delexicalizing Speech Segments for Prosodic Learning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional language teaching methods focus on grammar and vocabulary, neglecting prosodic characteristics like pitch, duration, and rhythm, which are crucial for fluent language communication, and fail to replicate the natural learning process of children who immerse themselves in interactive contexts.
Innovation Solution
A system and method that delexicalizes speech segments to provide prosodic speech signals, stores them, plays them for students, and records their responses to focus on intonation and rhythm, using MIDI encoding for musical resynthesis and comparison with native speech to improve language learning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional language teaching methods focus on grammar and vocabulary memorization, then students can learn language rules and translations, but they fail to develop fluent pronunciation and natural speech patterns
Solution Approach 1:
The patent extracts and isolates the prosodic characteristics (pitch, duration, rhythm, intensity) from the lexical content of speech. By delexicalizing speech segments and creating prosodic templates that contain only suprasegmental features, the system separates pronunciation patterns from vocabulary and grammar, allowing students to focus exclusively on mastering natural speech rhythms without the complexity of simultaneous language rule learning.
Solution Approach 2:
The patent creates prosodic templates that are copies of native speech patterns, preserving the acoustic characteristics of natural language. Students learn by imitating and comparing their speech against these stored prosodic templates, enabling them to replicate authentic pronunciation and rhythm patterns without needing to understand the underlying linguistic rules.
2Ease of operation
If students learn by translating from their native language, then they can understand grammar and syntax rules, but they produce halting and stilted recitation
Solution Approach 1:
The patent segments speech into distinct prosodic features (pitch contours, duration patterns, rhythm sequences, intensity variations) that can be independently analyzed and learned. By breaking down fluent speech into these manageable components stored as prosodic templates, students can progressively master each aspect of natural pronunciation rather than attempting to translate entire sentences, thereby improving speech fluency while maintaining learning accessibility.
3Quantity of substance
If language learning systems stress vocabulary and grammar, then students can build language foundation, but they neglect prosodic characteristics essential for fluent communication
Solution Approach 1:
The patent introduces prosodic templates as an intermediary between vocabulary/grammar learning and fluent speech production. These templates serve as a bridge that captures and preserves the prosodic information (pitch, duration, rhythm, intensity) that would otherwise be lost in traditional translation-based learning. Students use these templates to internalize natural speech patterns while building their vocabulary and grammar knowledge, ensuring neither aspect is neglected.

AI summary
A method and system for teaching non-lexical speech effects includes delexicalizing a first speech segment to provide a first prosodic speech signal and data indicative of the first prosodic speech signal is stored in a computer memory. The first speech segment is audibly played to a language student and the student is prompted to recite the speech segment. The speech uttered by the student in response to the prompt, is recorded.
