IBM ASI (Accessibility Speech Interface) version 1.20
This Web page contains installation programs for each language and platform specific version of the IBM ASI (Accessibility Speech Interface). After reading and agreeing to the copyright information which describes limitations on the distribution and use of the ASIs, download and install one or more of the ASIs.
Note: On AIX, all non-US English ASIs will include the installation of the US English TTS component.
If you need assistance with ASI installation you must contact the product support group for the product that uses the ASI. The IBM Human Ability and Accessibility Center provides this Web page as a convenient download location.
The system requirements for running on Microsoft® Windows® are:
- Windows 2000, Windows XP Home Edition, or Windows XP Professional.
- Intel® Pentium® 266MHz processor and 256K L2 cache or equivalent (including AMD-K6® with 256K L2 cache).
- 64MB RAM.
- Microsoft Windows-supported sound device.
The following information may be helpful if you encounter problems when installing or using an ASI.
No TTS (text-to-speech) engine installed
If you receive a message that says no TTS engine is installed when you start an ASI enabled application, you may have uninstalled ViaVoice TTS or some other speech program that uses ViaVoice TTS. To reinstall ViaVoice TTS, reinstall the ASI.
You may also receive this message if you do not have your sound card and its device driver installed and working. To determine if your sound card device driver is installed, try playing a .wav file using the Windows Media Player. Use Control + Escape to open the Start menu. Type P to open the Programs menu. Type A to open the Accessories menu. Type E to open the Entertainment menu. Type W to open the Windows Media Player. Using File, Open select a .wav file. The Windows Media Player should open the .wav file and play it. If it does not, check that the sound card device drivers are installed and at the latest level.
If you uninstall an ASI and then try to reinstall without restarting your system, you may get an error message during installation about problems replacing a .DLL. Restart your operating system and then reinstall the ASI.
The ASI removal procedure is platform dependent. The examples below describe uninstalling ASIs from a system containing US English and German ASIs, and in this scenario German was installed first.
For Windows, go to Start, Settings, and Add/Remove Programs. Remove the following entries from the Add/Remove Programs folder:
- IBM ViaVoice TTS Runtime v6.740 - US English.
- IBM ViaVoice TTS Runtime v6.740 - Deutch. (Note: On Windows, the last TTS Runtime you uninstall should be the one you installed first.)
- IBM Accessibility Speech Interface v1.20. (Note: Remove this item last, after uninstalling all the TTS Runtimes.)
For AIX, open the Application Manager window, then open the IBM ASI v1.20 window, then activate the "Uninstall Deutch" icon followed by the "Uninstall Base plus English" icon. Remove the base component last.
Note: If you uninstall an ASI, other applications that use text-to-speech may no longer work.
Problems when a speech product using ViaVoice TTS is installed after an ASI
If you receive an error message indicating the application which uses an ASI has errors, it may be due to installing a product using an older version of ViaVoice text-to-speech after installing an ASI. In many cases, the remedy to this problem is to uninstall all of your ViaVoice text-to-speech based products and any ASIs, reinstall your ViaVoice text-to-speech based products and then reinstall your ASIs.
Uninstalling an ASI does not remove ViaVoice TTS
When you uninstall an ASI, you do not automatically uninstall ViaVoice TTS. We recommend that you do not uninstall Via Voice TTS because other speech products may be using it for speech output.
Choppy or stuttering speech along with keyboard response problems
If you experience speech quality problems such as choppy or stuttering speech, one or more of the following may be true:
- You may not have enough processor speed, memory, or disk space. On Windows, ensure that you have at least a 266MHz Pentium® processor and at least 64MB of RAM. Additional processor speed, memory, and disk space can increase your speech quality and performance.
- If your sound card is a Sound Blaster 16, you may have an application called WaveSynth running. To reduce stuttering, disable this application by bringing up the Control Panel from the Settings menu that is on the Windows Start menu. Select the System icon and then the Device Manager tab. Find and select the WaveSynth application under the Sound, Video and Game Controllers device. Select the Properties button to bring up the device profile, and then check the box that says Disable in this hardware profile.
- You may have a down-level sound card device driver on your system. To check the device driver version, bring up the Control Panel from the Settings menu that is on the Windows Start menu. Select the System icon and then the Device Manager tab. Select the Sound, Video and Game Controllers device and then select your sound card device. Select Properties and the Driver tab. If the driver date is not within the last year, select the Driver File Details button to obtain additional information about your sound card provider and the device driver versions. Then you should call or find the Web site for your sound card vendor to verify that you have the latest device driver for your sound card. If you do not have the latest version, download or obtain the latest device driver and install it on your system.
