AI Multilingual Dataset Enhancement (Remote)

AppenTextClassification

In the AI Multilingual Dataset Enhancement project, I improved dataset consistency and quality for multilingual NLP systems. My tasks involved complex linguistic processing and data annotation to support more accurate AI models. I focused on ensuring cross-language accuracy and harmonization of labeled data. • Enhanced consistency across text datasets in English, French, Portuguese, German, Spanish, and Russian. • Applied linguistic methodologies to refine semantic structure. • Supported multilingual technology solution development through precise annotation. • Contributed to model training data for real-world language applications.

Speech Recognition QA (Appen Project)

AppenAudioTranscription

During the Speech Recognition QA (Appen Project), I conducted transcription alignment, accent variation labeling, and semantic quality assurance for English and French speech corpora. I carefully validated and corrected transcribed audio data to support the development of speech recognition models. The focus was on accurately capturing linguistic nuances in multilingual audio datasets. • Performed detailed audio-to-text alignment for speech data. • Annotated accent and semantic variations in diverse recordings. • Ensured high-quality, error-free transcriptions for AI training. • Supported both English and French language model improvement.
