I've written a rather simple Alexa Skill that play pre-recorded tales for children, recorded by professional actors (long better than mechanical voice of Alexa). Everything works fine, you can chose which kind of story and the story get chosen randomly from an array.
The problem is that I am actually play mp3 using SSML and it that limits the audio file to max 4 minutes.
I could cut the longer stories in multiple .mp3 files, but I don't know how to create a "progressive reply".
Any suggestion?
