A speech synthesizer. Made by TechniMusique et Parole Informatique (TMPI).
The device appeared on the French market and was apparently a ported version from the ORIC one, Oric being a popular machine in France.
Not much is known about this device.

- Caution - As seen in the schematic, only A0..A7 seem to be decoded, but A8..A15 aren't. If that is true, then the device can conflict with almost all other existing hardware, including important internal components: Gate Array, CRTC, ROM Bank, Printer Port, PIO and PSG (for these devices A0..A7 are don't care, so it's perfectly possible that some programs access them with FEh or FFh in lower address bits).

Schematic
This version uses an external unknown frequency oscillator. According to the schematic, speech is not injected to the SOUND pin on expansion port. /RD and /IORQ are decoded differently as in the other version. /WR is not used (instead the chips /W pin is wired to GND).
