TOPIC

    This article discusses PlainTalk Speech Recognition 1.5 compatibility with Power Macintosh G3 computers, as well as solutions to known issues.


DISCUSSION

    PlainTalk Speech Recognition 1.5 can be used with platinum colored Power Macintosh G3 computers. It cannot be used with Power Macintosh G3 (Blue and White) computers. PlainTalk 1.5.4 is compatible with the Power Macintosh G3 (Blue and White), iMac, and the Power Macintosh G3 with the DVD drive.

    Refer to article 60339: " PlainTalk: Using Speech Recognition 1.5.4 " for additional information.

    There are some issues you should be aware of before installing the Speech Recognition component of PlainTalk 1.5 on a Power Macintosh G3 desktop or minitower computer.

    Note: These issues do not apply to the PowerBook G3 or PowerBook G3 Series computers.

    PlainTalk 1.5 includes the following components:
    • English Speech Recognition
    • English Text-to-Speech
    • Mexican Spanish Text-to-Speech

    The English and Mexican Spanish Text-To-Speech software came with the Power Macintosh G3 (beige) minitower and desktop computers. Both installers can be found on the Apple Macintosh CD, which allows you to reinstall your computer's system software. These components have been tested, and are supported on Power Macintosh G3 computers. Please read the "Using English Text-to-Speech" and "Using Mexican Spanish TTS" documents included with these installers for detailed information on how to use this software.

    English Speech Recognition 1.5 does not come with the Power Macintosh G3 desktop or minitower computers. It has not been tested and is not supported on these computers. PlainTalk version 1.5.4, combined with Mac OS 8.6, are compatible with the Power Macintosh G3 (Blue and White), iMac, and Power Macintosh G3 computers with DVD drive. Refer to the following Knowledge Base article for additional information:

    Article 60339: " PlainTalk: Using Speech Recognition 1.5.4 "


    Here are solutions to known issues.

    Issue: MacinTalk 3 Voices Break Up With Virtual Memory On

    Description
    When Virtual Memory is turned on, you may hear stuttering or broken speech when using MacinTalk 3 voices.

    Workaround
    Turn off Virtual Memory in the Memory control panel and restart your computer. You can also prevent this issue by using a MacinTalk Pro voice (Victoria, Bruce or Agnes) from the Speech control panel. You can install the MacinTalk Pro voices using the English Text-to-Speech installer on the Power Macintosh G3 CD. MacinTalk 3 voices and MacinTalk Pro voice have different icons. The Voices folder in the Extensions folder contains all the voices used by Text-to-Speech and Speech Recognition. MacinTalk 3 voices have a "3" in their icon. MacinTalk Pro voices have a "P" in their icon.


    Issue: Audio Feedback From Built-in Monitor or External Speakers

    Description
    On both desktop and minitower Power Macintosh G3 computers, you may hear feedback if the monitor's built-in speakers or external speakers are too close to the PlainTalk microphone.

    Workaround
    Increase the distance between the PlainTalk Microphone and any external speakers. If you have a monitor with built-in speakers, turn the speaker volume down, or use headphones.

    Issue: Microphone Disconnected Error When Speakable Items is Starting Up

    Description
    On desktop Power Macintosh G3 computers with the audio card option, you may see an error message that says: "Speakable items could not run because the microphone is disconnected" while Speakable items is starting up.

    Workaround
    Select any sound input option other than the mic (like the CD-ROM) before turning Speakable Items on. Reselect the mic after Speakable Items has started up to use Speech Recognition.


    Power Macintosh G3 Computers With DVD Drive Are Incompatible With Speech Recognition

    Description
    Power Macintosh G3 computers (both the original beige and Blue and White models) that have a DVD drive are incompatible with Speech Recognition 1.5. These computers only record sound at 44.1 KHz. Speech Recognition 1.5 is incompatible with the 44.1 KHz setting.

    Workaround
    PlainTalk version 1.5.4, combined with Mac OS 8.6, are compatible with the Power Macintosh G3 (Blue and White), iMac, and Power Macintosh G3 computers with DVD drive. Refer to the following Knowledge Base article for additional information:
