Abstract
The invention provides a digital bidirectional intelligent voice explanation system that comprises a PC server and terminal devices and is based on a TTS. The PC server is used for management and configuration of corresponded files as well as all the terminal devices can work independently; therefore, the system has good stability. According to the current explanation system, pronounced explanation only can be carried out according to a prestored pronunciation text. However, the provided system is different from the current explanation system. All the terminal devices in the system can select to carry out pronunciation according to a prestored pronunciation text or directly carry out voice amplification on on-site sounds of a narrator; and the pronunciation explanation is not influenced by a machine; therefore; demand maximization can be realized; and when there is a fault on the equipment, an emergent measure can be taken. Pronunciation files are stored and managed in a test mode; occupied resources are small; application flexibility and maintainability are strong; and a pronunciation content can be changed by modifying a text. And voice identification key words are stored and managed in a text mode as well as configuration modification can be carried out on the key words according to different demands of venues; and even when exhibits in the venues are changed, rapid configuration can also be carried out by the server and thus the flexibility is strong.

Step 3, pickup unit receive narrator's voice control command;
Step 4, voice recognition unit find corresponding pronunciation text according to recognition result after the voice control command that receives is discerned in storage unit, and the text storage address of will pronouncing passes to TTS pronunciation unit;
Step 5, TTS pronunciation unit become the pronunciation text-converted of correspondence audio digital signals and pass to the D/A converting unit to convert analog voice signal into;
Step 6, judgement trigger receiving element and whether receive trigger pip: carry out local public address if there is the voice control command that then by the audio frequency switch unit pickup unit is received directly to be sent to power amplifier unit; If do not have and then switched analog voice signal to be passed to power amplifier unit and carry out power amplification, and send loudspeaker to and play by the D/A converting unit;
The terminal monitoring unit of step 7, PC server is monitored all end devices constantly; The timed sending querying command is given each end device; Wait for the return command of counterpart terminal device then, and the presence and the running status of counterpart terminal is kept in the terminal equipment database;
Beneficial effect of the present invention is:
1, native system is based on TTS, and wherein the PC server only supplies management and configuration corresponding document, and each end device can work independently, and possesses better stability.
2, can only pronounce to explain different according to the pronunciation text that prestores with existing introduction system; Each end device of native system can be selected by the pronunciation voicing text that prestores; Perhaps direct on-the-spot sound with the narrator amplifies; Not disturbed by machine, with maximization and the emergency measure when equipment breaks down of satisfying the demands.
3, the pronunciation file is deposited and managed with the form of text, and it is little to take resource, and application flexibility is strong, and is maintainable strong; Can change the sounding content through revising text.
4, the speech recognition key word is deposited and is managed with textual form, can be configured modification according to the different demands of venue, even when showpiece changes to some extent in the pipe then and there, can dispose fast through server equally, and dirigibility is very big.
