Dr. Henry L. Gray, Charles F. Frensley Professor of Statistics and Mathematics
Southern Methodist University ,Vice-President, Metroplex Voice Computing, Inc.


Metroplex Voice Computing, Inc. (MVC) continues to be the leader in speech recognition mathematics products for the physically challenged.

ArithmeticTalk™, MathPad™ by Voice™, VoiceEZ™MathType™, MathBrailleTalk™, MathTalk™ Scientific Notebook™ , VoiceEZcalc,Ô and VoiceEZcad™ are all proven hands/mouse free products. They currently use the Dragon Systems’ DragonDictate™ speech engine.

The current mission of MVC, along with updating and improving existing products, is the research and development of new educational products that take advantage of new speech recognition.

This presentation will demonstrate our new products in development, as well as our existing products. Some discussion will be given to the application of DragonDictate and NaturallySpeaking™.

We will now demonstrate our NEW PRODUCT:

MathTalk™ For Visually Impaired (MT/VI) – working with Mathematics Accessible to Visually Impaired Students (MAVIS) at New Mexico State University and several teachers/counselors of the visually impaired, a concept for a voiced mathematics program for the visually impaired was prepared. This program uses DragonDictate™ and Scientific Notebook™.

That concept has been beta tested and is now a reality.

The following will demonstrate features of this product:

  1. The "echo" of each voiced math command. ( User voices the math)
  2. An exclusive corrections feature for any misrecognitions. (User can correct)
  3. An exclusive technique that reads back math expressions/equations. ( User can select math on the screen for read back)
  4. An exclusive technique for saving and retrieving files. (User can manage files)
  5. Using the MAVIS Nemeth Braille Converter© (NBC) to convert the voice math into Braille.
  6. Use a refreshable Braille device to read the converted math and display as Braille. (This allows the user a final proof read of the math on the computer screen)

We will now demonstrate our existing products:


The beginning of mathematics is arithmetic. ArithmeticTalk was developed in response to educators' comments that higher mathematics programs were useless unless the student understood the basics. ArithmeticTalk meets this basic need. Dr. Gray wrote it to match the textbooks for grades two through five/six. The program utilizes MSWord (R)97 and DragonDictate(R)

The following is a live presentation of ArithmeticTalk showing how to do addition, subtraction, multiplication and division with voice. Notice how the voice commands make the student "voice" arithmetic language such as carry the 1, one's place, ten's place, dividend and divisor. Students can do arithmetic, and the program can assist teachers in preparing lessons/homework.

MathPad by Voice:

This is a presentation using MathPad™ with voice commands.

VoiceEZ™MathType™ (VE/MT):

VE/MT was created for students in grade 6 through Ph.D. With over 3,000 voiced math commands, users can voice from beginning algebra, advanced algebra, calculus and to Ph.D. and professional levels.

Numerous frequently used formulas such as quadratic formula, binomial formula, three d wave equation , Bessel function can be executed by just saying a SINGLE COMMAND.

The program uses Word97, MathType(TM), and DragonDictate. Mathematics is voiced in MathType and a toggle command allows movement to Word for text insertion and back to MathType for mathematics. The user can do math lessons and/or prepare complex papers/presentations.

We will now show a demonstration of VE/MT.


This program was specifically designed for a sighted person to very easily and rapidly voice math lessons/papers for a visually impaired person. Then just say "translate to braille" and "emboss this".

The program uses the Duxbury Braille Translator(R) (DBT) for Microsoft Windows® ,version 10.2, and DragonDictate.

The teacher does not have to remember hundreds of keystrokes or the Nemeth Math Code. Voice over 2,000 math commands , translate to Braille, and emboss. Users have said the time saving is about 50% over manual methods. Voice complex math such "quadratic formula", "3 x 3 matrix", and "binomial formula" with a SINGLE COMMAND.

We will now demonstrate Math Braille Talk.

MathTalk™/Scientific Notebook™ :

MathTalk/Scientific Notebook voices Scientific Notebook (TM) and Scientific WorkPlace (TM) . These are two powerful companion mathematics programs which contains a Maple (TM) feature. Do math grades 6 through graduate school levels. Professionals will find the Maple feature indispensable.

These programs will solve, factor, equate, and more. from beginning algebra to advanced calculus. Additionally, the programs also have GRAPHING CAPABILITIES. 2D polar, 3D polar, and 3 D rectangular are examples of voicing graphs.

We will now demonstrate MathTalk/Scientific Notebook .

Our web page has demos of all of our products – www.mathtalk.com

VoiceEZvb™ - a voiced version of Microsoft VisualBasic™ 6.0 – program in VisualBasic™ 6.0 with voiced commands

VoiceEZsounds™ - use non-standard sounds to access with the computer.

MathTalk/ScientificNotebook NSV- using Dragon Systems NaturallySpeaking™ to voice mathematics and text in Scientific Notebook. A Spanish Version is also being developed.

MathBrailleTalk NSV - using Dragon Systems NaturallySpeaking™ to voice mathematics and text in the Duxbury Braille Translator™.
