Multimodal Data Annotation Contributor – Audio Annotation & Transcription

AudioTranscription
As an audio annotator, I worked on Bengali speech datasets for AI training. I transcribed audio clips with attention to dialects and nuanced pronunciations, ensuring accurate representation of spoken language. I also labeled audio for speech recognition tasks and speaker intent classification. • Transcribed Bengali speech data into text. • Labeled clips for clarity (clean vs noisy) and intent. • Managed linguistic diversity across dialects. • Enhanced audio dataset quality for ASR models.

Multimodal Data Annotation Contributor – Image Annotation

ImageBounding Box
I contributed to multimodal AI dataset creation as an image annotator. My duties included labeling objects in images using bounding boxes and content-based tagging. I helped produce high-quality visual datasets for AI training and evaluation. • Labeled objects such as cars, people, and roads using bounding boxes. • Categorized images by content for dataset structuring. • Ensured labeling accuracy and adherence to project guidelines. • Assisted in quality assurance of labeled image data.

AI Data Specialist – Text Annotation & Classification (Bangla NLP)

TextClassification
I worked as an AI Data Specialist focusing on Bengali and Banglish text data. My work included data annotation, labeling, and evaluating AI-generated content for NLP research and abusive comment detection. Using context-aware approaches, I labeled and classified a large volume of Bangla social media comments for AI model training. • Collected and processed 10,000–15,000 Bangla comments from online platforms. • Labeled data into categories such as Not Abusive, Threat, Hate Speech, and Religious Hate. • Performed quality checking and context-sensitive interpretation. • Supported creation of accurate datasets for language modeling.
