Note for Acapela Infovox3: If a.exe process is not running and all Acapela voices say "Thank you for using this Acapela product" while trying, you have to run crac.exe again.
Note for Liepa TTS voices: If you want to add a new voice for Lithuanian TTS voice, make the same voice's name folder as a copy, go to "Garsu_bazes" with the link provided for completion rar files which it could be used to replace them with your copied folder, you have to create a register/unregister batch file that lets you remove or add SAPI5 voices with regsvr32 and make sure you always run with Administrator or else it won't work.
Note for Cepstral TTS voices: Since Cepstral is a older and free version, you need to find the license keys by yourself to activate them.
Note for CereProc TTS voices: CereVoice Dodo is the only main TTS voice that had a problem which slowly generates and makes a glitch into never-ending generation.
Note for Elan Sayso voices: If your trial period is running out, you have to find the program that lets you reset the demo trial to just use it again without the adapter.
Note for Loquendo 7 voices: Alan, Grace and Roberto TTS voices don't work.
