This Galixa Speech makes use of the Texas Instruments Galaxy 40x instead of the first generation Galixa Speech based on the TI-30 Galaxy.

This Galixa Speech is a scientific calculator with natural voice speech output. Numerical data on the display panel can be spoken digit by digit or as a complete number. It speaks all key functions: e.g. when the [SIN] key is pressed the calculator says "Sine"; these announcements can be repeated. It also has a built-in clock and alarm function. The volume can be adjusted using a knob.

The language of the Galixa Speech could be chosen between:

Swabian German

Main difference is the connection between the calculator and the custom specific speech electronics, instead a flat ribbon cable a flexible circuit board was chosen.

EHG Handy Tech Elektronik GmbH  introduced with the Galixa Braille the first scientific calculator with both speech output and a 10-cell braille display. The first calculator with a refreshable braille cell output was the Braillotron TI-2550 II developed by Mr. Schoenherr.

Don't miss other talking calculators like the TI-66 Calcu-Talk and the Orbit TI-34
