This makes two bookings, not one
The two studies are run for two different companies, under two separate agreements, so signing up here creates two bookings. You receive two confirmation emails, one per study, and each booking is managed and cancelled on its own.
Before you book
- You are a native US English speaker and can come to Berlin three times
- Your accent is California, Michigan, Colorado or Texas, which is what the Acapela study records
- The two Altavo appointments are recorded with sensors, video and audio
- The Acapela appointment is audio only, and nothing is filmed
- You record a short voice sample after booking, and Acapela confirm your place in their study
- You receive 130 EUR for the Altavo study and 70 EUR for the Acapela study, 200 EUR in all
- You can reschedule or cancel either study on its own
