Labeling Experience

Audio Data Labeling for Fake News Detection

AudioClassification
I participated in analyzing and labeling audio data as part of a fake news detection project. This involved identifying and categorizing elements of misinformation in speech samples. Consistency and accuracy in labeling were essential priorities in this role. • Labeled audio clips for misinformation detection. • Conducted transcription and further annotation as needed. • Validated correctness of labeled audio data. • Supported dataset preparation for machine learning models.
