A line connection switching apparatus performs connection switching of a communication line used both for speech communication performed by a telephone set and data communication performed by a facsimile apparatus and is inserted between the telephone set and the facsimile apparatus, and the communication line. When predetermined speech command information is input from a caller side through the communication line, a speech signal is detected by a switching unit. When a voice/silence discriminator discriminates that the speech signal represents voice, a voice interval monitor monitors a duration of the speech signal. If the duration of the speech signal falls within a predetermined range, the speech signal is stored in a speech signal storage unit. A pattern matching unit verifies whether a standard speech pattern of a speech signal registered in standard pattern dictionary unit matches with a speech pattern of the input speech signal stored in the speech signal storage unit. In accordance with a verification result, if the speech pattern of the input speech signal coincides with the standard pattern, the switching unit switches connection of the communication line to the facsimile apparatus.

In an intelligent work station of this invention, map information for a target is stored in a database. Word speech data input through a telephone line is recognized and analyzed, and the database is retrieved accordingly, so that map information specified by the speech input is extracted from the database. The map information is transmitted to a destination communication terminal. When the destination communication terminal does not have an image output function, the map information is analyzed, and document data representing the content of the map is created. The document data is speech-synthesized, and is output to the destination communication terminal via the telephone line.

Intelligent work station

In order to generate a series of speech parameters from a series of phonemic symbols extracted from a series of input characters, parameters for given syllables or phonemes are read from corresponding parameter files according to the types of immediately preceding vowels or consonants of the given syllables or phonemes in the series of phonemic symbols. The syllable or phoneme parameters ar combined to produce a series of speech parameters.
