Apply specific structural and acoustic tags: [N] for background noise [OVERLAP/][/OVERLAP] for simultaneous speech [LAUGHTER] for non-verbal laughter [PIL] for sensitive private information (addresses, phone numbers, IDs) [OIVS] for non-recording human background voices (TV, radio, background chatter) * for inaudible/unclear words Requirements & Qualifications Native or high-level proficiency in European Portuguese (EP).
