Hola.
I'm not sure I understand what kind of help you are looking for. If what you want is to add the audio of the translated verses, ScriptureForge will not create the audios, perhaps HearThis is the software you are looking for. This program will make it easy for you to record audio of biblical text from projects that are in progress: https://software.sil.org/hearthis/
Once you have an audio and timming file generated, you can import them into ScriptureForge by clicking on the icon I circled:
If you want to add questions in the form of audio, you can do so by clicking on the option "Add question".
Saludos,
Pepe.
