Labeling Experience

English Singing Voice Corpus Annotator

OtherAudioClassificationTranscription

As an English Singing Voice Corpus Annotator, I annotated audio at the phoneme level with detailed timestamping for a singing voice synthesis dataset. My work included labeling pitch and musical notes aligned with vocal segments to facilitate model training. I ensured consistency and reference to open-source standards in preparing a high-quality audio corpus. • Performed phoneme-level annotation with precise timing for each vocal segment • Labeled pitch, musical notes, and ensured temporal-musical alignment • Used Praat, sGTSinger, Audacity, ELAN, and Sonic Visualiser in annotation tasks • Reviewed annotations for consistency and dataset integrity
