====== Electronic Announcer ======

===== Overview =====

The Electronic Announcer is a hardware and software solution designed to provide automated public address announcements passengers and non-passengers within airport terminals and surrounding areas.

===== Components =====

The solution consists of both software modules (including modules developed by JetXBit) and hardware components:

  * [[pub:is_airport_resources|JetXBit Airport Resources Information System]] — used to:
    * create and edit announcement zone profiles;
    * create and edit [[ap:информационные_сообщения|message templates]] and manage announcement schedules.
  * [[ap:voiceinformer|VoiceInformer]] — an application that builds the announcement queue, converts text templates into audio announcements using a [[pub:TTS_Еngine|Text-to-Speech (TTS) engine]], and outputs them to the selected audio device.
  * [[ap:voicecontrol|VoiceControl]] — an application for monitoring the announcement queue associated with a selected announcement zone profile.
  * [[pub:web-сервис_с_производственной_информацией|Web Service]] — an intermediary service that connects the database with the client applications used for passenger announcements.
  * [[pub:TTS_Еngine|Text-to-Speech (TTS) Engine]] — a third-party software component or service used to convert text into synthesized speech.

The solution also includes the following hardware components:

  * Audio Station — an IBM-compatible computer equipped with one or more sound cards (audio channels), with the VoiceInformer client installed and configured.
  * Emergency Voice Alarm and Public Address System — the airport's public announcement system used to broadcast announcements and capable of connecting external audio sources (such as an Audio Station).

===== Technologies =====

To deploy the Electronic Announcer, complete the following steps:

  * Configure announcement zone profiles according to the required number of announcement zones.
  * Create message templates and assign them to the appropriate profiles.
  * Deploy and configure the [[pub:web-сервис_с_производственной_информацией|Web Service]].
  * Assemble and configure the required number of Audio Stations based on the number of announcement zones and available sound cards (audio channels):
    * install the [[pub:TTS_Еngine|Text-to-Speech (TTS) Engine]];
    * install and configure [[ap:voiceinformer|VoiceInformer]].
  * Integrate the Audio Stations with the airport's Emergency Voice Alarm and Public Address System.
