I entered what I thought was my Google Speech API Key into the dialog box that appears when using Method->"GoogleSpeech" with SpeechSynthesize. I also clicked the box to save the information. Thus, the wrong information was saved, but I cannot figure out how to delete or overwrite it.
I'm guessing SystemDredential will be involved, but I can't find any information specifically about the Google Speech API Key.
Any thoughts?
Thank you.
