English Singing Voice Corpus Annotator
Estimated Total Earnings: $1,200.00OtherAudioFixed Price
Project Overview
Contributors will be responsible for annotating a corpus of English singing voice recordings at the phoneme level using ARPABET, including marking the start and end of each phoneme with millisecond accuracy. In addition, each segment will require precise annotation of the pitch or note being sung. You will use reference materials such as GTSinger for accurate and consistent labeling across the dataset. Qualified contributors should have prior experience with audio annotation, familiarity with phonetics and pitch/note recognition, and strong attention to detail. Experience with singing voice data or music technology is a plus. Ability to follow scripted guidelines and produce accurate, high-quality labels is essential.
