B: Speech Engines and Devices
This chapter contains the following topics:
Software Speech Engines.
Hardware Speech Synthesizers.
Software Speech Engines
When you run Kurzweil 1000, it automatically detects the presence of any software speech engines you may have on your system, and lists all of the supported voices for each engine. 
Supported Software Speech Engines
Kurzweil 1000 supports the proprietary interface used by DECtalk™ Access 32.
Microsoft SAPI (Speech Application Programming Interface) versions 4 and 5, which enables you to use the growing number of next-generation SAPI-compliant speech engines as they become available.
However, because SAPI is a complex and evolving standard, we cannot guarantee flawless support for every engine while in the Kurzweil 1000 environment.
Hardware Speech Synthesizers
The following is a list of the hardware speech synthesizers Kurzweil 1000 supports. We expect the list to grow. Please contact us if you want to use one that may not be part of this list.

Supported Hardware Speech Synthesizers
SSIL-Compliant Devices
If you are using the Microsoft Windows 95, Windows 98 or Windows ME operating system, the Kurzweil 1000 installation process lets you choose an SSIL-compliant engine. Simply follow the instructions you hear as the installation proceeds. Refer to the Installation and New Features Guide.
Important Notes: 
	You should have a software speech engine correctly installed before performing the SSIL installation for Kurzweil 1000. This lets you use Kurzweil 1000 even if the SSIL device fails.
	You must have the device connected correctly before installing Kurzweil 1000.
DECtalk™ Express, DoubleTalk™, TripleTalk™ and DECtalk USB
DECtalk Express, DoubleTalk and TripleTalk support is available for Kurzweil 1000 on Microsoft Windows NT, Windows 2000, Windows XP operating systems.
If you are using TripleTalk, you may need to upgrade TripleTalk firmware to version 0x0201 or later. Use the program that comes with the TripleTalk called TTUInfo to find the version number. If it isn't current, contact Access Solutions (www.axsol.com) for a free upgrade. Speech will not work reliably with older versions. Note that you will need to update the DLLs, go to Access Solutions’ Web site (www.axsol.com) for details.
For DECtalk USB, once the device is connected to your system, it will be available from the Engine list in the Voices Settings tab page. Note: For the DECtalk USB device to work properly with Kurzweil 1000, the firmware version must be dated 11/19/2004 or later. Updates are available from Access Solutions.
For both DECtalk Express and DoubleTalk, you must configure the device connection once in Kurzweil 1000. TripleTalk users do not have to do this, as Kurzweil 1000 is able to get this information automatically. 
To configure DECtalk Express or DoubleTalk in Kurzweil 1000:
Before you proceed, be sure:
	You have installed and connected the device.
	There is a screen reader on your system.
	You know which communication port the synthesizer is plugged into.
1.	Navigate to C:\Program Files\ Kurzweil Educational Systems\Diags and open the HWSpeech program icon.
2.	Specify the device you have installed. 
3.	Select the COM port it's on, then press the ENTER key.
