Locate the sound connections and connect the speaker jack to the computer. Most computers use an internal sound card and often the connections are in the back of the computer. These are a series of connections the same size and diameter as the speaker jack. In many cases there are two sound out connections:
    One will be labeled as a line-out connection. Most speakers that require a separate power supply (such as an electrical (AC) adapter or batteries) should use this connection. It is also used to export amplified sound to recording devices including recordable CDs and tape cassette systems.
    The other connection is for the non-powered speakers. Because the signal is boosted by the computer, powered speakers may be damaged if connected. 
Plug the speaker into the proper connection.
To test the connection, follow these steps:
    Click Start, click Control Panel, and then double-click Speech.
    On the Text-to-Speech tab, click Preview Voice to hear the currently selected voice. The text is spoken and the words are highlighted as they are spoken. If the speakers are working properly, you will hear the spoken words. 
If you do not hear sound after you connect the speakers, see the "Possible Text-to-Speech Problems" section of this article for troubleshooting procedures. 

Click Start, click Control Panel, and then double-click Speech.
On the Text-to-Speech tab, click Audio Output.
Select either Use preferred audio output device or Use this audio output device.
    Use preferred audio device sets the output device as the default for the system. Select this option if you want to use the same output device for speech as all other sound for the system. It is also the default option for Speech properties. Often, computers will have only one output device, such as a pair of speakers. The default device is designated in the appropriate sounds or multimedia properties in Control Panel for each operating system. Additional information for the specific panel is available through the associated Help files.
    Use this audio output device allows you to select another device for speech programs only. The drop-down list is active if other devices are available. In this drop-down list, select the device that you want. This does not change the default device for other audio programs. For example, you may want all speech output to go through your headset rather than the speakers.

A Text-to-Speech voice is closely associated with a particular speech engine. It may not be clear from the displayed name which language a voice is using. After selecting a speech engine or voice, test the voice and language by clicking Preview Voice.
The language or voices supported by a speech engine may not be obvious from the engine's displayed name. Refer to the specific user's guide for detailed information about the engine. This includes not only the language supported, but also the lexicon purpose. The lexicon purpose indicates whether it is a general grammar or jargon specific to a profession such as legal or medical.
Microsoft does not provide additional speech engines (voices), but a number of third-party products are available that support the new Microsoft Speech API. For information on these products, visit the following Microsoft Web site:
