Speech recognition requirementsTo use speech recognition, you need the
following hardware and software components:
A high-quality close-talk (headset) microphone. A Universal Serial Bus (USB)
microphone is recommended.
A 400 megahertz (MHz) or faster computer with 128 megabytes (MB) of memory.
Microsoft Internet Explorer 5.0 or later.
The speech recognition engine must be installed. It is available with
Microsoft Office XP, but might not have been installed.
To add speech recognition
Speech recognition is normally added automatically as a text service when it
is installed. Use this procedure only if it you removed it as a text service
and want to add it.
Open Regional and Language Options in Control Panel.
On the Languages tab, under Text services and input languages, click Details.
Under Installed services, click Add.
In the Input language list, click an input language.
Select the Speech check box, and then click an option in the list.
Speech overviewSpeech capabilities for a computer system refers to the
ability to play back text in a spoken voice (referred to as text-to-speech or
TTS), or to convert a spoken voice into electronic text (referred to as
speech recognition or SR). The two capabilities are independent of each
other. Many systems will have only TTS. SR may be installed later either by
loading a speech package, or more commonly, through an application which has
incorporated speech into it. For example, a new word processor or office tool
suite may include speech and it will be loaded at that time.
In general, speech-enabled applications will use Speech properties in
Control Panel to access and control features. In this way, speech may be
customized for your personal preferences or a specific office location. Since
TTS and SR may be loaded at different times, it is possible that not all the
Help will be applicable. In cases where SR is not available, references to SR
help and SR procedures may be ignored.
