Artificial intelligence already has a human voice




Neural networks allow Google to interpret a text and apply similar intonations to a person




Siri, Alexa, Cortana; they are some of the virtual assistants of the American technological giants. One of these names was added a few years ago: the Google Assistant. Paa the search giant has put many resources to get unseat Apple as the king of the audience.

Through the Deepmind laboratory, responsible for the Artificial Intelligence (AI) of the company, Google has managed to develop a synthetic voice with a precision almost identical to that generated by a human being.

This technology is called Tacotron 2, whose operation is based on two neural networks capable of interpreting the text and applying the effects, pauses and intonations that are present in it.

From the American portal Quartz indicate that one of the novelties of this version is the ability to pronounce names and difficult words, as well as distinguish punctuation marks or if a part of the text requires to be pronounced with a different intonation.

This system allows you to transform the text into speech first, recreating the text in a spectrogram, that is, graphically forming the words in the form of waves so that the Google Wavenet software interprets them and then transforms them into a voice.

So far, Tacotron 2 is in the testing phase, available only in English and played by a female voice. Although, the company intends to train other versions in different languages ​​and interpreted by a male voice.

The dog-robot Aibo of Sony devastates in the presale This intelligent animal is capable of creating emotional connections with humans | It's an update that Sony launched in 1999 and costs 1,480 euros    The domestic robot Aibo, an intelligent dog capable of creating emotional connections with humans launched today by the technological giant Sony, sold out all its stock during the early sale. The first series of artificial pets has been delivered to their owners, after three rounds of pre-orders were exhausted last year, explained a spokesman for the company, who declined to disclose the number of units sold.    The first 30 owners of the Aibo received their dog-robot at a special ceremony at the Sony headquarters in Tokyo, in which the company wanted to celebrate its return to the world of domestic robotics after 12 years. Aibo, an update of the pioneering dog-robot that Sony launched on the market in 1999 , maintains the name of its predecessor, but incorpor...

Artificial intelligence is able to pre-empt medical diagnoses The Alphabet project can predict when a patient will get worse Alphabet, the parent company of Google, and the US Department of Veterans work hand-in-hand to take the technology to the patients' rooms to monitor and monitor possible changes in the health status of the elderly. However, this union is not about electronic devices to monitor the heartbeat or to control blood pressure or tension, but both companies work on the deployment of DeepMind, the artificial intelligence of Alphabet. According to several medical studies, one out of ten deaths in hospitals occurs after obviating any change in the patient's health status. The Alphabet project and the US administration will analyze patterns of 700,000 anonymous medical records to see if Artificial Intelligence from DeepMind can identify which patients will get worse during admission to the hospital and find out their future doctor DeepMind and its engineers say that ...

The technology that will allow to save the Tables of Daimiel

The technology that will allow to save the Tables of Daimiel A project by WWF and Coca-Cola creates tools for saving millions of liters of water per year    Las Tablas de Daimiel is a wetland that spans more than 3,000 hectares of La Mancha. They once occupied ten times more territory, but the overexploitation of the water that nourishes this treasure of biodiversity has left them at a minimum. Cereal crops such as corn and barley, melons, eggplant orchards, onions and garlic and, of course, the vineyard of La Mancha still competes for water from the aquifer 23, a key part of the hydrological system of the Upper Basin of the Guadiana River and essential contribution for the Las Tablas wetland.     To reverse this situation, WWF and Coca-Cola launched the Mission Impossible project, which since 2012 seeks to return this immense bag of water of more than 5,500 square kilometers to a healthy state. Since then, the participating farms have saved around 2,500...
