About AI Training Work

AI training is the human work behind modern artificial intelligence. Contributors transcribe and review audio, label data, and prepare examples that help AI systems understand real-world language and speech.

This fully remote contract work offers a flexible way to contribute to cutting-edge technology. Many projects can be completed without prior AI experience, especially when you bring strong language skills, careful attention to detail, and reliable independent work habits.

The Role

OpenTrain AI is seeking a Brazilian Portuguese Audio Transcriptionist to create high-quality transcriptions for AI training datasets. You will listen to real-world recordings in Brazilian Portuguese and apply detailed conventions to capture natural speech, including crosstalk, multiple speakers, informal language, and non-verbal sounds.

This is an entry-level, part-time contractor role for candidates in Brazil. The work is fully remote and asynchronous, with a time requirement of 20 or more hours per week. Compensation is $10-$35 USD per hour.
