S-SYN-PT (Speech Synthesis Port)
The TN725B Speech Synthesis circuit pack provides four independent Speech
Synthesis Ports which may be connected to any of the voice time slots on the
Time Division Multiplex (TDM) Bus. Each Speech Synthesis Port consists of a
speech synthesizer device (SSD) and is managed by a custom-coded
programmable speech synthesizer (PSS) controller. The PSS controller is, in turn,
controlled by the on-board microprocessor via a command interface specifically
designed for this application. The PSS controller’s main function is the orderly
transfer of encoded speech from the speech vocabulary read-only memory
(ROM) to the SSDs. The SSDs decode it and produce 64 kb/s 5-255 PCM (Pulse
Code Modulation) speech. The encoded speech is stored in up to 512K bytes of
on-board ROM. In addition, each Speech Synthesis Port has an associated
dual-tone multifrequency receiver (DTMR) to receive touch-tone digits from a
station set connected to the port via a voice time slot. The station set may be
connected to the Speech Synthesis Port through either a line or trunk circuit.

When there is an incoming call to a port, the ‘‘listen’’ network time slot is
connected to the DTMF receiver input and the ‘‘talk’’ network time slot is
connected to the SSD output. This enables the Speech Synthesis Port to support
speech synthesis features or touch-tone input with voice response features.
Some of the features that use the Speech Synthesis Port’s capabilities include
Leave Word Calling, Automatic Circuit Assurance, Automatic Wakeup
(hotel-motel), and Do Not Disturb (hotel-motel).

The Speech Synthesis circuit pack should not be confused with the
Announcement circuit pack. Different voice features are supported by each
circuit pack.
