File 16.0, 16.3-16.5: Language and computers (F) Flashcards
Word spotting
Program focusses on words it knows and ignores the ones it doesn’t
Limited domain
Programs perform better when their use is restricted to a limited domain
Spoken-language dialogue system
Make use of less complex types of systems such as interactive systems that produce but don’t understand speech, or systems that present options verbally but require the user to answer by pressing buttons.
Isolated speech
The user speaks the input clearly and without extraneous words
Continuous speech
The input can be more like normal speech
Barge-in
The user interrupts and talks over the computer. Systems differ as to whether they can deal with this.
Automatic speech recognition
Involves the use of computers to transform spoken language into written (or computer-understandable) language
Language processing and understanding
Often a deep analysis is required, including building syntax tress tonfigure out the inputs structure
Parsing
Analyzing sentences syntactically is known as parsing
Dialogue management
The system needs to understand the intentional structure of the conversation
For example, the main intention is to schedule a travel itinerary, but this goal can be achieved by accomplishing certain subtasks.
Error recovery
Getting the conversation back on track after a misunderstanding
Text generation
Involves the use of computers to respond to humans using natural language by creating sentences that convey the relevant information
Speech synthesis
The words that make up the generated text must be converted into a sequence of sounds
Wizard of Oz simulation
In which users think they are interacting with the actual computer system, but in fact, a hidden human controller simulates some aspects of the system
This is used to test the system and change any defaults.
Translation
The task of converting a text written in one language (source language) into a text in another language (the target language)
