Generating phrases with Python Wizard

[Lateralleap]

I believe I followed the instructions correctly for installing and running the wizard gui

When I run it, it seems to ignore the "-f arduino" parameter and starts in python format. I then change it manually to arduino format

I record a .wav file using Microsoft Sound Recorder in medium (lowest) quality mode

When I load the .wav file with the gui, it generates a byte sequence

However when I copy that sequence into a sketch that is successfully synthesising text from the large vocab example, all i get is a high pitch squeak for the new phrase I recorded

Here is the byte stream it generated:

I then trie using Auacity. I set it for mono recording and experimented with different audio settings but still just got garbled audio

Any ideas?

Thanks
