SAPI comes with several free voices from Microsoft. Other voices (from NeoSpeech) may be purchased and installed separately.
You need to select a default voice for speech. To select the voice, open the Speech tab in e-Speaking and press the Speech Properties button.
Click on the Text-To-Speech tab and look at the Voice Selection box. Change the selected voice to Microsoft Mary and press the Apply button.
If you have downloaded another voice to your computer, you may select that voice from the list. The "bla bla bla" voice is the Sample TTS voice.
