Voice messages
Contents
Voice messages can be used during call alerting and telephone operation. Wave files which already exist can be imported or voice messages can be created in Expert with Text-to-Speech.

1.Text-to-Speech

Voice, Speaking speed and Volume can be selected in the Program settings of Expert for generation with Text-to-Speech. The generation takes place once before the transfer of the data. When the voice, speaking speed or volume is changed, all texts are regenerated.
Note
Microsoft(tm) Speech API 5.1 or higher is required to generate voice messages.

The Expert does not supply any languages of its own for the generation. A help function for the installation can be found here.

Note
Each voice message requires a unique key in the project.
