Data Annotator – Audio Annotation

RemotasksRemotasksAudioAudioTranscriptionTranscription

As part of my audio annotation responsibilities, I transcribed speech data, performed speaker diarization, and tagged environmental and audio events. My annotations supported audio processing, speech recognition, and speaker identification systems for AI applications. Quality assurance reviews and adherence to guidelines were integral to my workflow. • Transcribed speech audio with high accuracy • Identified and separated speakers in recordings • Tagged sound events and environmental cues • Upheld strict data protection and confidentiality protocols
