SelfTalker is a family of digital message repeaters designed for point-of-purchase displays and
other general purpose applications. These sound boxes can play natural sounding voice messages, music or sound effects. There are no moving parts in the unit, hence no degradation of voice quality due to mechanical
wear and tear. Each delivery of the message is as good as the first one throughout the product life.
Message announcement is activated by either a built-in motion sensor or a push button. It is ideally suited
for use to unobtrusively bring a passerby’s attention to an article, a service or an event in a promotional campaign or to deliver a message of aution to an apporaching person for possible dangers.
SelfTalkers are available in different styles at different price/performance ratio. Some are built to last for permanent displays, and some are designed for low-cost disposable applications. Some offer high voice
quality for the most demanding projects, and some provide moderate voice quality at bargain prices.
Two kinds of SelfTalkers are available: recorders and players. SelfTalker recorders can record and play
messages for virtually unlimited number of times. A built-in microphone and a line in jack are provided for message recording. Once recorded, the message is kept in the non-volatile internal memory until it’s
re-recorded. The SelfTalker recorders are ideal for applications requiring frequent message change or message recording by end users in the field. However, SelfTalker recorders are generally more expensive than
SelfTalker players.
SelfTalker players can not record any messages on their own, they can only play pre-programmed messages. Some models use interchangeable message cartridges to facilitate message change in
the field. Instead of re-recording the message like SelfTalker recorders, these players’ message can be changed by replacing the message cartridge. SelfTalker players offer slightly better sound quality than the
SelfTalker recorders, and are more cost effective when mass produced.
All SelfTalker units come complete
with plastic enclosure, speaker and battery holder. Some have built-in motion sensor, some have built-in push button, and some have detached push button. They can be powered by batteries or DC adaptors. Different
models are offered with different amount of memory.
