Yes Survey Voices is a legit company and they do payout the money once you reach the threshold to be paid out.
You can make money taking online surveys but don't expect to replace your job with taking online surveys for money as it can take awhile to make the payout and they're not that easy to do and sometimes there's no surveys available.
Most people give up on taking surveys before ever reaching the payout but if you stick with it and even take surveys in your spare time when you're not doing anything else then you can earn some extra income taking online surveys.
