When you upgrade to Speechdio Business, you get the following Business features in your Speechdio account:

1. Ability to upload text file instead of pasting script inside Speechdio App.

2. Use virtually unlimited length of text per speech file. *

* Fair Use Policy applies.

* Speechdio Business unlocks unlimited length of speech file but the cloud storage accounts may not support extremely large file creation. So make sure you keep your files within few thousands words. If you enter an extremely long script, file creation may not be successful. In such case, make sure you divide your script into multiple chapters and use those chapter. 

* When you are using longer scripts, make sure you are using a cloud storage like your Google Drive and/or DropBox. Don't try creating large files on the in app local storage.
