SP-3

Speech Processor Module

1. INTRODUCTION

The SP-3 speech processor is an advanced electronic
record/playback module for short voice messages, up to 20
seconds long. Designed for manual recording and electronically
triggered playback, the SP-3 provides 1 Watt of audio output.

The primary application of the SP-3 is an inexpensive, easy-to­install automatic announcer, triggered by motion detectors or any
type of momentary switch. The module is suitable for automatic
transmission of verbal warnings, announcements, guidance and
advertisements in elevators, stairwells, corridors, exhibitions, etc.

A miniature microphone and an easily accessible RECORD
pushbutton are included in the module. Loudspeaker output
terminals are provided for direct connection to an external
loudspeaker. An audio input header permits the installer to choose
(by the corresponding jumper, as shown in Figure 1) between
recording a message with the internal microphone (INT) and
recording a message from an external audio source (EXT).

When triggered by a short pulse, the speech processor plays the
recorded message once and then stops. With continuous
triggering, the message is repeated over and over again, until the
trigger voltage is removed.

The module is suitable for mounting within a host system cabinet or
inside the loudspeaker housing. The SP-3 may be supplied
mounted in a small plastic cabinet with a built-in 63 mm / 1 W (2­1/2" / 1W) loudspeaker.

Installation Instructions

Operating power is drawn from the host system or from an
external 12 VDC supply.

3. INSTALLATION

Use the 3 mounting holes of the SP-3 (Figure 1). Remember to
leave adequate clearance between the bottom of the PCB and
any metal surface.

3.1 Triggering with a Motion Detector's
Normally Closed Switch

To operate the speech processor as an automatic announcer
triggered with a motion detector’s N.C. terminals or with any
momentary N.C. switch, proceed as follows:

A. Connect an 8-ohm / 1 Watt loudspeaker across the SIG and

12V (–) terminals.

B. Connect the motion detector's N.C. terminals or the

momentary N.C. switch between the voice processor's ST+
and 12V (–) terminals.

C. Use the jumper provided with the unit to short the two ST pins

permanently together (these pins are clearly identified in
Figure 1).

D. Connect the 12 VDC supply to the 12V (+) and (–) terminals,

taking care not to reverse the positive and negative leads.

E. Record a message as explained in Section 4.

3.2 Triggering with a Normally Open
Switch

To operate the speech processor as an automatic announcer
triggered with any momentary N.O. switch, proceed as follows:

A. Connect an 8

terminals.

B. Connect the momentary N.O. switch between the speech

processor ST+ and 12V (+) terminals. A second method is to
connect the N.O. switch between the ST– and 12V (–)
terminals. A third method is to connect the N.O. switch across
the two pins of the ST header on the printed circuit board.

C. Connect the 12 VDC supply to the 12V (+) and (–) terminals,

taking care not to reverse the positive and negative leads.

D. Make sure that the jumper is removed from the two ST pins. A

good practice is to mount the jumper on a single pin, to
prevent it from getting lost.

E. Record a message as explained in Section 4.

4. RECORDING AND TESTING

Note: Make sure that a jumper is mounted across the two INT
pins of the audio input header. If you intend to record from an
external audio source, remove the INT jumper and connect the
external audio source across the EXT (+) and (–) pins.

A. Complete all connections as explained in Section 3 and power

up the system.

B. Push and hold down the REC button, and after approximately

one second start to speak, at normal voice level at the
distance about 25 cm (10") from the microphone. When
through, release the pushbutton. Remember that message
duration is limited to 20 seconds.

Note: It is advisable to make the recording in a quiet

environment. Turn off nearby radio receivers and noisy
machines, and ask people in your immediate vicinity to keep
silent while you record. If the background noise is too high,
speak closer to the microphone.

C. If you exceed the 20 second limit, the last part of the message

will overwrite its first part, making the message incoherent.
Initiate playback (see step D below) to verify that this has not
occurred. If the message proves too long, rephrase it to
reduce its duration and record again.

D. To initiate playback for testing purposes, momentarily short

together the two ST pins on the PCB. The message will be
played back once. Repetitive playback will result if the pins
are kept shorted together.

E. The speech processor is now ready for regular service, and

will play back the last recorded message whenever triggered.
