About AI Training Work

AI training is the human side of building artificial intelligence. People prepare and review examples such as transcripts, translations, images, and model responses so AI systems can better understand and produce useful language.

In this role, your careful listening and Brazilian Portuguese expertise will help improve the quality of speech data used to train AI.

• Fully remote work using a computer, web tools, and audio playback interfaces
• Flexible, asynchronous scheduling that can fit around other commitments
• Direct contribution to how modern AI systems understand spoken language

The Role

OpenTrain AI is seeking a Brazilian Portuguese Audio Transcript Editor to review machine-generated transcripts against audio recordings. You will correct transcription, punctuation, and formatting errors, verify word-level accuracy, and ensure timestamps and timing alignments are precise.

You will also identify unclear audio, overlapping speakers, and other quality concerns that could affect the reliability of speech data. This is an entry-level role, and no prior AI background is required.

• Contract, part-time role
• Fully remote and asynchronous
• Expected commitment: 10 to 40 hours per week
• Pay: $10 to $35 per hour
• Role description specifies Lisbon or elsewhere in Portugal

What You’ll Do

You will work independently through web-based tools and audio playback interfaces, applying detailed style and formatting standards consistently across transcript tasks.

• Listen to Brazilian Portuguese audio recordings and compare them with existing transcripts
• Correct missing, misspelled, or incorrectly transcribed words
• Fix punctuation and formatting problems
• Check word-level timestamps and timing alignments
• Flag unclear passages, overlapping speakers, and other audio quality issues
• Maintain high accuracy across transcript data

Requirements and Helpful Background

You should have native or near-native Brazilian Portuguese proficiency with excellent written command of the language. Success requires strong listening skills, careful attention to fine details, and the judgment to interpret speech accurately when audio quality varies.

Experience is helpful but not required. Background in transcription, language work, audio quality assurance, or annotation can make the workflow familiar.

• Native or near-native Brazilian Portuguese and excellent writing ability
• Ability to accurately understand spoken Portuguese when audio quality varies
• Strong judgment when correcting missing, misspelled, or incorrect words
