CrowdGen is seeking native German speakers in Germany aged 18 and older who own an iPhone 17 series device to record short, one-sided phone calls for AI voice training. Participants must improvise natural customer service calls using fictional details across 4 to 10 sessions in a quiet indoor space. The remote project pays $4.30 per QA-approved session, with total earnings ranging from $17.20 to $43.00.
