APPENDIX A SAMPLE DICTIONARY SESSION
Let us look at an example of how a dictionary file can be used. Suppose we
had a program that used the abbreviation "Mr." a lot by placing "Mr." in the
dictionary, Hearsay Gold can be trained to say "MISTER" instead of trying to
say "MR". The following procedure will show how to create a dictionary file to
accomplish this.
1. Reboot computer to be sure Hearsay is not installed (CTRL-ALT-DELETE or
turn it off then on again) and bring up the DOS prompt (>A: or >C: as
is appropriate for your system). Insert the Hearsay program disk into
drive A (If your DOS prompt is >A:) or (If your DOS prompt is >C:)
change directories to your Hearsay directory.
2. Type SPEECHV2 [ENTER] or SPEECHV3 [ENTER] (As appropriate for your
installation) and wait for the DOS prompt to return.
3. Type SP-EDIT [ENTER].
4. Respond to the Version prompt by indicating whether you are using
Version 2 or Version 3.
5. Enter your port assignment and press [ENTER].
6. If adding to an existing dictionary, press F7 to load the dictionary &
enter the drive and path for the dictionary to be added to if it does
not already appear on the screen. Then use the cursor to select the
dictionary file and press [ENTER].
7. When the Speech Editor menu comes up, press F1 to enter the WORD window.
8. Type "MISTER".
9. Press F2 to convert the word into the appropriate phonomes.
10. Press F4 to hear the phonemes. If it does not sound right to you, then
edit the phonemes using [F3] until it sounds the way you want it to.
11. Press F5 to add these phonemes to the dictionary. Enter [MR.] when
asked for the the name of the word. Now "Mr." is in the dictionary with
the phonemes for "MISTER".
12. Press F3 [CTRL-HOME] to clear the phoneme window.
13. Press F1 [CTRL-HOME] to clear the word window.
14. Type "MR." F2
15. Press F4 to hear how it sounds. If it does not sound right, re-edit the
phonemes with [F3] or press F6 [*] [ENTER] [Y] to erase the dictionary,
press F3 [CTRL-HOME] to clear the phoneme window, press F1 [CTRL-HOME]
to clear the word window, and go back to step 7.
16. To save the dictionary, insert a formatted disk into the disk drive if
saving to floppy disk, then press F8. If saving to the hard drive press
F8, & enter the drive path name, then press [ENTER]. Enter a filename.
17. To exit the editor, press [CTRL-F1], Y.
18. To load the dictionary into the Hearsay Gold's memory, first reboot the
computer and then install Hearsay, then insert the disk containing the
dictionary file into the disk drive.
19. Press the [ALT]+HEARSAY key to bring up the Hearsay Main Menu.
20. If "F7 - Return When DOS Is Not Busy" is displayed on the Hearsay menu,
press F7 and [Y] and wait for DOS to be ready.
21. When the Hearsay Menu returns, press F6, F5.
22. Enter the name of your dictionary file & press [ENTER]. Your dictionary
is now loaded.
The same procedure can be used to add any word, phrase or initials to the
dictionary.

APPENDIX F GENERAL INFORMATION
HOW TO USE THE PC INTERFACE
This section provides technical information for users who have special
interface problems or wish to connect their own microphones, speakers, or other
equipment to the Hearsay Gold board. The first section describes the interface
between the Hearsay Gold and the IBM PC bus. The second section describes the
audio input and output specifications.
PC INTERFACE
The Hearsay Gold circuit board is mapped into the IBM PC I/O bus at one of
sixteen port addresses. If you are using a game interface or another option
board that is also mapped to any of these I/O addresses that the Hearsay Gold
is set to, it will not operate properly.
PORT SWITCHES
The PORT switches on the Hearsay board must be set to values that do not
conflict with other devices you are using for your PC. The Interrupt switches
are for future expansion and should all be set to OFF. We recommend that you
first try setting the PORT switches to 34 (3 and 4 ON, and the others OFF).
Every device used by the IBM PC has a port assignment, & the Hearsay Gold
must be assigned to one that is not used by any other device.
As shown in the following table, only the last three ports are used in
normal operation, and add-on devices usually use lower numbered port addresses.
We have been unable to find any other device using PORT ADDRESSES 0390 and 0397
which is selected by a port setting of 34 (3 and 4 ON) & 1 and 2 OFF), so this
setting will probably work with your PC.
If you find these settings do not work, the tables below show the other
possible port combinations, and any of them will work as long as they do not
conflict with other devices you are using.

INTERFACING MICROPHONES AND SPEAKERS
The microphone connection is the ring (Center) of the mini stereo plug
that plugs into the mini stereo jack located on the back panel of the Hearsay
Gold board. The speaker connection is the tip and the base is ground to both
microphone and speaker. The mini stereo jack is designed to mate with standard
mini stereo plugs such as the ones used for the headphones of personal stereos.
Most powered personal stereo extension speakers can be used directly with
Hearsay Gold by plugging them into a stereo to dual mono adapter. Particularly
useful are the ones that have individual volume controls on the speakers. The
audio jack will only play through one of the speakers. The speaker output jack
is also compatible with any speaker designed for use with a mini phone plug
output such as found on inexpensive cassette recorders although the volume is
relatively low without additional amplification.
NOTE: We do not recommend that you wire your own interfaces for the Hearsay
Gold unless you are experienced in electronics design and construction
techniques. Of course we can not be responsible for the results or damage
of any such interface.
PLUG CONNECTIONS
The headphone and speaker jack are wired as follows:
The tip of the plug to the positive (+) speaker connection.
The ring of the plug (Center) to the positive (+) microphone connection.
The base of the plug (Section of shaft closest to body of plug & cable),
to the speaker ground & the microphone ground.
MICROPHONE INPUT SPECIFICATIONS
Type Electret, close talking, noise cancelling
Pickup pattern Cardoid (Unidirectional)
Impedance load (Nominally 150 ohms)
Open circuit voltage = -47.0 db (4.5 mv)
Power level = -66.0 db
Frequency response 200 Hz - 5,000 Hz
NOTE: The microphone cable must be shielded.
SPEAKER OUTPUT SPECIFICATIONS
Impedance 8 ohms
Power output 500 Mw
APPENDIX G TROUBLESHOOTING GUIDE
INSTALLATION PROBLEMS
To install the Hearsay, it is necessary to install the Hearsay board in
your PC, connect the headset and load the software. Installation instructions
are provided in Book I.
Once the board and headset are installed, you can test them by running the
following test programs.
STEP ACTION
1. Type CD\Hearsay
2. Type RECOGTST
3. Follow the appropriate prompts
If Hearsay does not work, check for the following problems:
1. Wrong Program or Insufficient Memory - Voice Recognition requires 80K
with HSR, 120K with HSRE; speech synthesis requires 160K for Version 2
and 210K for Version 3 beyond what your other software uses.
2. Incorrect Board Installation/Switch Settings - Turn off your PC (Unplug
the monitor and anything else that is plugged into electric (AC power))
open it up again, & check that the Hearsay board is properly installed.
Take it out of the slot and check that the port switch is set properly.
Put the board in again, making sure it is in straight. Make sure the
headset is plugged into the back of the Hearsay board. Put it all back
together, turn it on again and try the test programs again.
3. Conflicting Port Assignments - See Appendix F for an explanation of the
port assignments. If you are using the port assignments described above
for something else, you will get a conflict and Hearsay will not work.
If you have other devices connected to your PC that might be causing a
problem, try changing the port switch settings to one of the other
values shown as described in APPENDIX F.
4. Defective Board or Software - The Hearsay hardware and software are
quality tested before shipment, but defects are still possible. If your
Hearsay package is defective, call the Customer Service Department at
(516) 234-8300 from 9:00 am to 5:00 pm Eastern time, Monday to Friday.
OTHER PROBLEMS
There are two basic types of problems you may encounter after you have
successfully installed Hearsay. They are:
Hearsay no longer does something it used to do.
or
Hearsay does not do something you think it should do
If it used to work but now it does not, check your software first. Could
it have been damaged in some way? Assuming you made backup diskettes when you
first received the product and saved the originals (As directed in the
instructions) you can check this easily. If you are using Hearsay software from
a CD-ROM, just reinstall it. CD-ROM software is virtually impossible to erase.
DO NOT TRY TO RUN HEARSAY FROM THE ORIGINAL DISKETTES. If you are having a
problem with your PC, it is possible that it is damaging your software. Make
another copy of your original diskettes and run those.
If reloading the software does not help, look for what has changed. Did
you add another device to your PC that may have conflicting port assignments?
If your board or headset is damaged, they can be returned to the vendor
you bought them from for exchange. If you can not find the trouble yourself,
you can call Hearsay Customer Service for assistance.
If it doe not do what you think it should, consult the manual. Maybe it is
working it is supposed to. Again, if you have read the manual and you still can
not find the answer, Customer Service will be glad to help you out.
