The work involves audio segmentation, speaker role tagging, and accurate verbatim transcription. Key Responsibilities Audio Segmentation & Alignment: Segment audio line-by-line based on semantic coherence (average segment length: 5–6 seconds; maximum 8 seconds). Maintain clean silence margins around audio cuts (100ms–150ms) while avoiding speech truncation or sudden noise inclusions.

Verbatim Transcription & Special Tagging: Provide verbatim transcription matching spoken words exactly. Transcribe numbers as full words (no Arabic numerals allowed). 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). Note: Audio entirely in Brazilian Portuguese (BP) is considered invalid for this project. Exceptional listening skills and high attention to rule-based guidelines. Prior experience with audio annotation tools (DataPlus, Audacity, Praat, CVAT, or similar) is preferred. Ability to meet strict quality benchmarks: Word Transcription Accuracy: ≥ 98% Speaker Role Accuracy: ≥ 97% Special Label Accuracy: ≥ 90% How to Apply Please submit your proposal including: Your rate per audio hour.

Hello, I’m very interested in this European Portuguese audio annotation and transcription project. I have experience working with European Portuguese and a strong understanding of the linguistic differences between European and Brazilian Portuguese. I’m comfortable working with detailed transcription guidelines and paying close attention to speaker identification, verbatim accuracy, pauses, background noise, overlapping speech, and special annotation labels. I understand that this project requires European Portuguese specifically and that Brazilian Portuguese audio is not acceptable. I can carefully follow the required rules for segmentation, speaker roles, IDs, and verbatim transcription, including the specific acoustic and structural labels provided in your guidelines. My rate is **$30 per hour of audio**. I’m available for approximately **4–6 hours per day**, depending on the daily workload, and I can start immediately. I’m reliable, detail-oriented, and comfortable working with strict quality benchmarks. I would be happy to complete a sample or qualification test if required. I look forward to the opportunity to contribute to the project.
