Labeling Experience

Freelance Data Annotator

OtherAudioTranscription

I contributed to machine learning applications by performing audio data transcription and annotation. My tasks included listening, identifying, and tagging audio elements as per project guidelines. I ensured that each transcription met quality benchmarks for use in speech recognition models. • Transcribed and labeled audio clips for speech data analysis. • Utilized annotation software suitable for audio labeling. • Verified accuracy of all transcriptions against source audio. • Followed strict project timelines and protocols.
