Speech recognition
Automatic conversion of spoken language into text Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also known as automatic speech recognition (ASR), computer speech recognition or speech to text (STT). It incorporates knowledge and research in the computer science, linguistics and computer engineering fields. Some speech recognition systems require "training" (also called "enrollment") where an individual speaker reads text or isolated vocabulary into the system. Speech recognition applications include voice user interfaces such as voice dialing (e.g. The term voice recognition[3][4][5] or speaker identification[6][7][8] refers to identifying the speaker, rather than what they are saying. From the technology perspective, speech recognition has a long history with several waves of major innovations.
Army, Air Force ‘Squarely Focused’ on Project Convergence 21 Wargame: Generals
JADC2, Lockheed Martin image WASHINGTON: Army and Air Force generals said Tuesday the two branches are closely collaborating and “squarely focused” on delivering capabilities for Project Convergence 21. PC21 is the second annual Army-hosted exercise focused on digitally connecting and tactically coordinating (“converging”) disparate cutting-edge technologies in harsh real-world domains. While PC20 was largely about coordinating different Army Futures Command projects, with some participation by the Marines and Special Operations, PC21 is all about “joint mission threads” across the different US services. Army Maj. The task ahead for PC21 and future PC exercises is mammoth and entails integrating “millions of lines of code,” according to Air Force Brig. A key Air Force component of PC21 and the broader JADC2 vision is its Advanced Battle Management System, which is designed to demonstrate technology to underpin the Air Force’s implementation of JADC2.
Lionel Naccache, Le Nouvel Inconscient. Freud, Christophe Colomb des neurosciences
1Voici un ouvrage qui bousculera bien des certitudes. Celles des spécialistes des disciplines de l’esprit, au premier chef, mais par ricochet, les croyances naïves des anthropologues. Lionel Naccache propose au lecteur de suivre cette odyssée à travers son expérience de jeune clinicien, neurologue à l’hôpital de La Pitié Salpêtrière à Paris et chercheur en neurosciences cognitives à l’inserm. Rompu aux méthodes de l’imagerie cérébrale fonctionnelle, il réfute une « inquiétante » néophrénologie, mais aussi la neuropsychologie clinique standard, en effectuant des allers et retours entre patients neurologiques ou psychiatriques et sujets « sains », pour décrypter la vie mentale et en restituer l’inépuisable richesse. 2L’ouvrage se divise en trois parties. 3Existerait-il alors une représentation mentale qui serait spécifique des pensées conscientes ? 4La troisième partie est consacrée à « Freud, Christophe Colomb du mental ». 7Quel livre !
Computer Weekly - Cities worldwide band together to push for ethical AI
From traffic control and waste management to biometric surveillance systems and predictive policing models, the potential uses of artificial intelligence (AI) in cities are incredibly diverse, and could impact every aspect of urban life. In response to the increasing deployment of AI in cities – and the general lack of authority that municipal governments have to challenge central government decisions or legislate themselves – London, Barcelona and Amsterdam launched the Global Observatory on Urban AI in June 2021. The initiative aims to monitor AI deployment trends and promote its ethical use, and is part of the wider Cities Coalition for Digital Rights (CC4DR), which was set up in November 2018 by Amsterdam, Barcelona and New York to promote and defend digital rights. It now has more than 50 cities participating worldwide. He said that by sharing best practice in particular, cities will be able to avoid repeating previous mistakes when deploying AI systems.

Speech synthesis
Artificial production of human speech A synthetic voice announcing an arriving train in Sweden. Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products. A text-to-speech (TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic transcriptions into speech.[1] The reverse process is speech recognition. The quality of a speech synthesizer is judged by its similarity to the human voice and by its ability to be understood clearly. History[edit] Long before the invention of electronic signal processing, some people tried to build machines to emulate human speech. In the 1930s Bell Labs developed the vocoder, which automatically analyzed speech into its fundamental tones and resonances.

Arts de la mémoire : les principes de la mémorisation – Formation 3.0
Quels sont les principes de mémorisation utilisés dans les arts de la mémoire ? Comment mémoriser des quantités d’informations sans se tromper ? Quel rôle peuvent encore jouer les arts de la mémoire à l’ère numérique ? Ce sont quelques questions que je me pose depuis quelques années. Les arts de la mémoire ont connu une longue éclipse avant d’être remis à l’honneur par les livres de Dame Frances Yates. Mais quels sont les principes qui ont été utilisés par les « mnémonistes » au cours des 3 derniers millénaires pour mémoriser tant des discours que des poèmes ou des formules de mathématiques ? Trois principes fondamentaux En fait, ces principes sont au nombre de 3.
