About AI Training Work
AI training is the human side of building modern artificial intelligence. People prepare and review examples such as transcriptions, recordings, annotations, and model responses so AI systems can understand language and real-world communication more effectively.
Audio transcription work is especially important for teaching AI to recognize natural speech, regional accents, multiple speakers, background noise, and informal language.
The Role
OpenTrain is seeking a Brazilian Portuguese Audio Transcriptionist to create accurate transcriptions of spoken Brazilian Portuguese audio for AI training. You will listen to real-world recordings and follow detailed style guides to capture speech precisely, including challenging audio with crosstalk, background noise, filled pauses, and informal expressions.
This is a fully remote contractor role with flexible scheduling and task-based work. The role description provides a 10 to 40 hour weekly range, while the structured listing indicates 20+ hours per week. Compensation is listed as $15 to $35 per hour based on experience and assignment, with a structured pay range of $10 to $35 per hour.
