Cepstral is the text to speech (TTS) software used in Freedom Fone. Our software will work without a licence but before it reads each line of text, Cepstral will play a reminder that you need to buy a licence. We are using the Allison 8 Khz voice for Linux.
You will be hearing this voice because you have entered text in the large text box labeled Description in your Voice menu. If this is not what you want, you can remove this text and it will stop this problem.
A licence for the Allison 8 Khz voice for Linux can be bought from https://www.cepstral.com/. Once you get the licence you can register the voice by running the swift executable from the command prompt as follows:
Follow the instructions to enter the details associated with your licence. You will be asked for Name, Organisation and Licence key
If you use your own audio files you do not need to use text to speech at all!
The chances are that the file you tried to upload was larger than the maximum file size of 10MB allowed. Downsize the audio file by shortening its duration and/or ensuring it has been created as a WAV or MP3 file that is mono with a sampling rate of 8Khz.
Characters other than a-z, 0-9 or - and _ can create problems in filenames when you upload the files. If you see the File not found message when you try to play uploaded audio content, try re-uploading the content with a filename that follows the about rules.
There has been error in communication with Booktype server. Not sure right now where is the problem.
