Abstract
A method is described for operation of a dialog system (1) with a speech input interface (2) and an application (3) co-operating with the speech input interface (2). The speech input interface (2) detects audio speech signals (AS) of a user and converts these into a recognition result (ER) in the form of binary data which can be used directly by the application. This recognition result (ER) is provided by the application (3). A method and a system for production of a corresponding speech input interface (2), a speech input interface (2) and a dialog system (1) with such a speech input interface (2), are also described.
Claims25
A method for operation of a dialog system (1) with a speech input interface (2) and an application (3) co-operating with the speech input interface (2) in which the speech input interface (2) detects audio-speech signals (AS) from a user and converts these directly into a recognition result (ER) in the form of binary data which can be used directly by the application (3).
A method for production of a speech input interface (2) for a dialog system (1) with an application (3) co-operating with the speech input interface (2) and comprising the steps:
- specification of valid speech input signals (AS) by a formal grammar (GR), where the valid vocabulary of the speech input signal is defined in the form of terminal words of the grammar (GR),
- provision of binary data representing the semantics of valid audio speech signals (AS) and comprising data structures which are directly usable by the application (3) at system run time and generated by a program part of the speech input interface (2) and/or program modules (PM) directly executable by the application (3), and/or the provision of program parts which generate the binary data
- allocation of the binary data and/or program parts to individual or combinations of terminal words or non-terminal words to reflect a valid audio speech signal (AS) in appropriate semantics,
- translation of the program parts and/or program modules (PM) into machine language such that on operation of the dialog system (1), the translated program parts generate data structures directly usable by the application (3) or on operation of the dialog system (1), the translated program modules (PM) can be executed directly by the application (3).
A speech input interface (2) for a dialog system (1) for voice control of a device or method by a user, which with co-operates with an application (3) of the dialog system (1) and detects audio speech signals (AS) and converts these directly into a recognition result (ER) in the form of binary data which can be used directly by the application (3).
A system for production of a speech input interface (2) of a dialog system (1) comprising a syntax specification tool with which valid audio signals (AS) of the dialog system (1) are specified by a formal grammar (GR), where the valid vocabulary of the audio speech signal (AS) is defined in the form of terminal words of the grammar (GR), and a semantic definition tool for provision of program modules (PM) and allocation of the program modules (PM) to individual or combinations of terminal words such that after translation into machine language, on operation of the dialog system (1) the translated program modules (PM) can be executed directly by the application (3).
