Speech Evaluator – TTS MOS-8 French Speech Evaluation

Audio
In the TTS MOS-8 French Speech Evaluation project, I assessed AI-generated French speech samples for clarity, naturalness, and pronunciation using Mean Opinion Score (MOS) methodologies. I identified and documented instances of robotic tone and provided recommendations to improve voice naturalness. This work directly supported the improvement of French synthetic voices. • Evaluated a wide set of TTS samples for speech quality • Scored audio based on established MOS criteria • Identified and cataloged issues with pronunciation and naturalness • Contributed to enhancing the human-likeness of AI-generated speech.

Writing Specialist – Airplane_Gearshift Writing Development Project

TextText Generation
Within the Airplane_Gearshift Writing Development Project, I created and refined AI-generated written content to improve output clarity, coherence, and relevance. I performed comparative analysis of various generations and enhanced the quality of selected outputs. The work helped align AI outputs to high editorial standards. • Authored and corrected multiple AI-generated drafts • Validated language, logic, and writing structure • Conducted in-depth comparative evaluations of text outputs • Implemented high-quality linguistic benchmarks.

Evaluator – Cypher_Eval_C Certified Evaluation Project

Text
During the Cypher_Eval_C Certified Evaluation Project, I evaluated and compared AI model text responses. This included applying structured scoring systems, selecting optimal answers, and ensuring evaluation rigor. My efforts contributed to the consistency and reliability of model improvements. • Used certified evaluation frameworks for model outputs • Applied task-specific scoring and selection rules • Ensured adherence to strict evaluation criteria • Optimized the evaluation process for reproducibility and clarity.
