Inside the PX

The PX shipped with a 2048 word vocabulary twice the original design amount this "firmware"

This vocabulary is phonetic, and the PX can actually load new files right from your computer.

We plan to release some alternate vocabulary files in the months to come.

Equipped with an internal  speaker the PX also has an external audio jack as well.

This  jack is for NON-Amplified speaker only 8 to 32 ohms with a 1/8 inch stereo jack.

Plugging in an amplified speaker will shut down the audio output of the PX.

The PX voice is driven by a SpeakJet TM speech synthesizer.  Powered by two AA batteries

We recommend Lithium or Lithium rechargeable batteries .  The Heart of the PX is a

Pic  Microprocessor  running at 16 MHz .  The Internal speaker is Mylar to be moisture resistant.

The main System board is double sided  smt / and thru hole

The PX has no user servicable parts or adjustments inside the PX
