A method for voice recognition, wherein a diagram method with integrated unequivocal syntax restriction is combined with an N-gram voice model with statistical word sequence evaluation in such a way that alternative recognition methods can be used in different segments of a word sequence.

Voice recognition using a grammar or N-gram procedures

A speech dialog system wherein a process for automatic control of devices by speech dialog is used applying methods of speech input, speech signal processing and speech recognition, syntatical-grammatical postediting as well as dialog, executive sequencing and interface control, and which is characterized in that syntax and command structures are set during real-time dialog operation; preprocessing, recognition and dialog control are designed for operation in a noise-encumbered environment; no user training is required for recognition of general commands; training of individual users is necessary for recognition of special commands; the input of commands is done in linked form, the number of words used to form a command for speech input being variable; a real-time processing and execution of the speech dialog is established; and the speech input and output is done in the hands-free mode.

Process for automatic control of one or more devices by voice commands or by real-time voice dialog and apparatus for carrying out this process

In a method for real time speech input of a destination address into a navigation system, the speech statements that are entered by a user are recognized by a speech recognition device and classified in accordance with their recognition probability. The speech statement with the greatest recognition probability is identified as the input speech statement, with at least one speech statement being an admissible speech command that activates the operating functions of the navigation system associated with this speech command. (All the admissible speech statements being stored in at least one database.) According to the invention, at least one operating function of the navigation system comprises an input dialogue. Following activation of that operating function, depending on the input dialogue, at least one lexicon is generated in real time from the admissible speech statements stored in at least one database, and the generated lexicon is loaded as vocabulary into the speech recognition device.
