You have to Construct a Polly Audio object and pass this into the Request information before calling “Synthesize Speech“
You must now call “Destroy Polly Audio” to mark the audio object for deletion, otherwise it will not be garbage collected
You can now get the duration of the audio in seconds using “GetDuration” function
Polly Client Objects are now constructed asynchronously, projects should no longer “hang” for several seconds due to slow DNS resolving. However, you must wait until the Client object has been constructed!
