English Call Audio Annotation Specialist

Human Audio Annotation Specialist (hourly, start immediately). Listen to recorded English customer-support phone calls and annotate them manually, without using any AI tools: mark the exact start and end time of each stretch of speech (to the millisecond), transcribe it word for word, and label who is speaking and whether they finished their turn, following a provided guideline. Attention to detail and strong listening skills required. Worldwide, $8-15/hr, under 30 hrs/week, 1 to 3 months. Please share any audio transcription or annotation experience.
