You can use
Text Speaker's Talking Reminders feature to read your file at a scheduled time. You can also set a repeat interval, so that the file will be read every day.
To add a reminder, go to Tools >> Talking Reminders. Next, click on the Create button and enter a start date and time. Set the repeat interval of 1 day. Select the ‘Text File Containing Message’ option and click the add file icon to choose the file. Select the file on your network path. Click the OK button to save the reminder details.
A reminder will start at your selected time and your file on the network drive will be read aloud.
