Informatique affectiveL’informatique affective ou informatique émotionnelle (en anglais, affective computing) est l'étude et le développement de systèmes et d'appareils ayant les capacités de reconnaître, d’exprimer, de synthétiser et modéliser les émotions humaines. C'est un domaine de recherche interdisciplinaire couvrant les domaines de l'informatique, de la psychologie et des sciences cognitives qui consiste à étudier l’interaction entre technologie et sentiments.
Speaker recognitionSpeaker recognition is the identification of a person from characteristics of voices. It is used to answer the question "Who is speaking?" The term voice recognition can refer to speaker recognition or speech recognition. Speaker verification (also called speaker authentication) contrasts with identification, and speaker recognition differs from speaker diarisation (recognizing when the same speaker is speaking).
Hartley (unit)The hartley (symbol Hart), also called a ban, or a dit (short for decimal digit), is a logarithmic unit that measures information or entropy, based on base 10 logarithms and powers of 10. One hartley is the information content of an event if the probability of that event occurring is . It is therefore equal to the information contained in one decimal digit (or dit), assuming a priori equiprobability of each possible value. It is named after Ralph Hartley.
PsycholinguistiqueLa psycholinguistique est un domaine d'étude scientifique interdisciplinaire, auquel collaborent psychologues expérimentaux et linguistes théoriques qui désirent comprendre la nature fondamentale du langage. Elle s’intéresse aux processus cognitifs mis en œuvre dans le traitement et la production du langage. Fondée dans les années 1950, elle fait appel à de nombreuses disciplines, telles la linguistique, la neurologie et la neurobiologie, la psychologie et les sciences cognitives.
Plasma speakerPlasma speakers or ionophones are a form of loudspeaker which varies air pressure via an electrical plasma instead of a solid diaphragm. The plasma arc heats the surrounding air causing it to expand. Varying the electrical signal that drives the plasma and connected to the output of an audio amplifier, the plasma size varies which in turn varies the expansion of the surrounding air creating sound waves. The plasma is typically in the form of a glow discharge and acts as a massless radiating element.
Shannon (unité)Le shannon est une unité de mesure logarithmique de l'information. L'unité est égale à l'information contenue dans un bit dont la valeur est imprévisible et les deux valeurs également probables. 1 Sh ≈ 0,693 nat ≈ 0,301 . La quantité d'information contenue dans un message est ainsi le nombre de bits minimal pour le transmettre ; soit le logarithme en base 2 du nombre de possibilités de messages différents dans le même code. La compression de données consiste à rapprocher le nombre de bits du nombre de shannons.
SemEvalSemEval (Semantic Evaluation) is an ongoing series of evaluations of computational semantic analysis systems; it evolved from the Senseval word sense evaluation series. The evaluations are intended to explore the nature of meaning in language. While meaning is intuitive to humans, transferring those intuitions to computational analysis has proved elusive. This series of evaluations is providing a mechanism to characterize in more precise terms exactly what is necessary to compute in meaning.
Invoke (smart speaker)Invoke (stylized as INVOKE) is a smart speaker developed by Harman Kardon and was powered by Microsoft's intelligent personal assistant, Cortana. Voice interaction with Cortana provides features such as setting alarms, facts, searches, weather, news, traffic, flights, and other real-time information. Additionally, the speaker's Cortana integration with one's Microsoft Account enabled calendars, reminders, commutes, to-do lists, and home automation features, among others.
