Speech engines

A speech engine is software that gives your computer the ability to play back text in a spoken voice (referred to as text-to-speech or TTS).

MapPoint supports TTS and includes a speech engine that is compatible with the Windows XP and Windows Vista operating systems. You can use a different speech engine as long as it is compatible with Speech Application Programming Interface (SAPI) version 5.1.

To view and change settings for most speech engines, in Control Panel, open Text to Speech (or Speech). By using the Text-to-Speech feature, you can control the voice properties, speed, and other options for text-to-speech translation.

To determine whether TTS is working properly in Windows 7:

  1. In Control Panel, click Ease of Access.

  2. Click Speech Recognition.

  3. On the left side, click Text to Speech.

  4. Click Preview Voice.

To determine whether TTS is working properly in Windows Vista or Windows XP:

  1. In Control Panel, open Text to Speech (if you use Windows Vista) or Speech (if you use Windows XP).

  2. Click Preview Voice.

Note   If the text in the box above Preview Voice is spoken audibly, with each word highlighted in turn, TTS and the speakers are working. If you cannot hear the preview voice and see the words highlighted as they are spoken, see Troubleshoot navigation.
