A Deep Image Recognition-Based Automatic Evaluation Method for English Speaking Interaction Behaviors Enhanced by Attention Mechanisms
Bibliographic record
Abstract
Against the backdrop of globalization and the rapid advancement of intelligent education, English speaking interaction ability has become a core competence in international communication.Traditional manual evaluation methods suffer from low efficiency and strong subjectivity, making them inadequate for large-scale, objective assessments.Therefore, research on automatic evaluation methods for English speaking interaction behaviors is of significant practical importance.Current studies often rely solely on audio features, overlooking critical visual cues such as facial expressions and body movements, which results in incomplete assessments.While some approaches attempt to incorporate visual information, traditional image recognition models struggle to capture key features in complex interactive scenarios and lack effective mechanisms for integrating multidimensional features.To address these challenges, this study proposes an automatic evaluation method for English speaking interaction behaviors by integrating attention mechanisms with deep image recognition.The core contributions of this research are twofold: (1) the development of an interaction behavior recognition model based on an optimized attention mechanism, which consists of a global feature branch for holistic image feature extraction, an improved window-based attention branch for focusing on local key regions, and an enhanced channel attention branch for reinforcing important feature channels; (2) the design of an automatic evaluation framework that utilizes the accurately extracted features from the recognition model in conjunction with established speaking interaction assessment criteria to perform comprehensive evaluations.The innovations of this study lie in: (a) the proposed multi-branch attention model that enables precise extraction of global, local, and channel-specific features, overcoming the limitations of traditional models in feature representation; and (b) the deep integration of visual recognition with evaluation logic, establishing a complete technical pipeline from feature extraction to final assessment.This method significantly enhances the objectivity and accuracy of evaluations and offers a novel solution for intelligent spoken English assessment in the education domain.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
