No
The original VecVoice used the GI SPO256. The SpeakJet (in the AtariVox) has the same allophone set (and a few extras), so the microcontroller (in the AtariVox+) uses a lookup table to selects them in real time (during the serial data stream).

Correct
If you flash the interface with CTS not inverted, it will not work in Phrasalator (with hardware flow enable). I used this as a 'normal serial' test.
-
Check if the USB interface has the attached settings.
You'll need this utility - https://www.ftdichip.com/Support/Utilities/FT_Prog_v3.8.128.448 Installer.exe

I remember the USB interface failing on really long phrases in Phrasealator. But a conventional serial port interface (powered by an external PSU) worked fine.
AAMOI I've always found USB-serial interfaces not to be as reliable as actual serial ports.
-
I set the FTDI_RL CTS to inverted (firmware is flashable through the USB).
Also, CBUS0 and CBUS1 (connected to the AVox's EEPROM) are set to I/O mode. I was hoping someone would one day code an EEPROM util.
-
This is the schematic for the interface. AVox buffer full is connected to serial Clear To Send (CTS) pin.

There's a possibility this could be because of a faulty / different variant sound chip in the Vec.

Did you PM me here ? (it's not come through)

PM'd

A multicart with a fixed number of games on is pretty much out of date as soon as you buy it.

FYI this is what the cart looks like now (new PCB / label / LED)

It requires re-programming the microcontroller.

That would be cool

I can do it for you if you send me the EEPROM's (it's in a socket).

Just built another batch if anyone wants one ?

Perhaps you had a bad copy.

Here's a different version of the case with built-in speaker.

The current version (that AA sells) looks like the PCB below and uses the DIP settings (below)
