1. How long: Babel publishes no review time, and no acceptance rate. After the sample, its team reviews each application by hand, so a week is not unusual by what we know. Some applicants report staying "under review" with no decision. Keep your email and phone active, since that is where Babel contacts you. Whether you can chase it, only Babel can say.
2. If selected: you pass an ID check (a selfie step with limited attempts; reviewers say a failure is final, so use good light and a valid ID). Then you connect PayPal, Venmo or a bank through Dots and pick projects. New projects start with a lower daily limit that rises as your work meets quality standards.
3. Pay: the Bengali transcriber role posts up to $110 per audio hour transcribed. That is a ceiling, not a typical rate, and an audio hour takes several hours of work. The Bengali voice actor role posts $60–$150 per hour, but it asks for professional voice-acting experience and an external mic. Babel says voice-acting rates outside the US are location-based and shown on the dashboard before you record, so the posted range may not apply to you. Pay comes every Tuesday for the week before, with no minimum and no fees.
If you are not accepted, the job list has a General Application.
