Information output system, communication terminal, information output method and computer product

An information output system that outputs at a communication terminal, information provided from an information providing apparatus, wherein

• the information providing apparatus comprises:
• a receiving unit that receives position information of the communication terminal and sequentially receives information related to a plurality of search expressions included in random speech of a user of the communication terminal,
• a searching unit that, based on the position information and the information related to search expressions included in the random speech, searches a wide area network for vicinity-related information related to a vicinity of the communication terminal, the vicinity-related information being searched for each time a search expression is received,
• a converting unit that converts into audio data, the vicinity-related information retrieved each time a search expression is received, and
• a transmitting unit that sequentially transmits to the communication terminal, the audio data converted by the converting unit;
• and
• the communication terminal comprises:
• an extracting unit that extracts the search expressions included in the random speech of the user,
• a transmitting unit that transmits to the information providing apparatus each time the extracting unit extracts a search expression, the position information of the communication terminal and information related to the extracted search expression,
• a receiving unit that sequentially receives from the information providing apparatus, the audio data indicative of the vicinity-related information for the communication terminal, retrieved based on the information related to the search expressions,
• a storage unit that stores therein the audio data sequentially received by the receiving unit,
• a detecting unit that detects a determination expression that is included in the random speech of the user and that is for outputting any one among the audio data stored in the storage unit, and an output unit that if the detecting unit detects a determination expression, outputs from the storage unit, the audio data that is specified based on the timing when the determination expression is uttered and that is indicative of the vicinity-related information for the communication terminal.

A communication terminal used in an information output system and comprising:

• an extracting unit that extracts search expressions included in random speech of a user;
• a transmitting unit that transmits to an information providing apparatus each time the extracting unit extracts a search expression, position information of the communication terminal and information related to the extracted search expression;
• a receiving unit that sequentially receives from the information providing apparatus, audio data indicative of vicinity-related information for the communication terminal, retrieved based on the information related to the search expressions;
• a storage unit that stores therein the audio data sequentially received by the receiving unit;
• a detecting unit that detects a determination expression that is included in the random speech of the user and that is for outputting any one among the audio data stored in the storage unit;
• and
• an output unit that if the detecting unit detects a determination expression, outputs from the storage unit, the audio data that is specified based on the timing when the determination expression is uttered and that is indicative of the vicinity-related information for the communication terminal.

An information output method performed by a communication terminal that outputs information provided from an information providing apparatus, the method comprising:

• extracting search expressions included in random speech of a user;
• a transmitting unit that transmits to the information providing apparatus each time a search expression is extracted at the extracting, position information of the communication terminal and information related to the extracted search expression;
• receiving sequentially from the information providing apparatus, audio data indicative of vicinity-related information for the communication terminal, retrieved based on the information related to the search expressions;
• storing to a storage unit, the audio data sequentially received at the receiving;
• detecting a determination expression that is included in the random speech of the user and that is for outputting any one among the audio data stored in the storage unit;
• and
• outputting from the storage unit, if a determination expression is detected at the detecting, the audio data that is specified based on the timing when the determination expression is uttered and that is indicative of the vicinity-related information for the communication terminal.
