TTSMaker conversion history is what you previously converted from text to
speech. It can be used to view and redownload previously generated audio
files.
For the sake of user privacy, all user conversion records have a validity
period of only 30 minutes, allowing users to download the files to their
local devices within that time.
Conversion records are stored in the cache of the user's browser to ensure
user privacy and data security.
You can find the "History" or "Conversion History" link on TTSMaker's main
page, and clicking on it will allow you to view your conversion history.
TTSMaker's conversion history doesn't have a storage limit, but it
automatically deletes expired content to make space for new ones.
There are two possible reasons. Firstly, your conversion records may have
expired and were automatically deleted by the system. Secondly, you may not
have performed any conversions yet. You can return to the homepage to
perform text-to-speech conversions and then refresh the current page.
