Yup, that is the current version. Can you let me know the sentence with which you are getting pops, so I can check it out? The recordings on the page are also made from the Simulator with version 1.1, so it could be something restricted to particular words which I can investigate and hopefully fix.
Please let me know your Xcode version, target SDK, and Simulator version with which you’re hearing issues along with the sentence so I can set up a test. Thanks!
