If there is no recording associated with a user's name, then the system checks the user's mailbox or Data Source entry and translates the "Name" text into speech. Sometimes, especially when names contain accented characters, the playback may not provide an accurate pronunciation. (For example, the name "L'Abbé" may be pronounced as "Lab".)
For this reason, we strongly recommend you encourage users to record their names (either through a tutorial, or using the SAA "name recording" command.)
