Baidu’s text-to-speech AI can replicate hundreds of accents

Virtual assistants give our smart devices seemingly human personalities, but despite their efforts to sound like real people, programs such as Apple Inc.’s Siri and Microsoft Corp.’s Cortana still sometimes sound a little robotic. Chinese web giant Baidu Inc. aims to change that with Deep Voice, an artificial intelligence designed to convert text into believable human speech. Today, Baidu announced the release of Deep Voice 2, the second iteration of its text-to-speech AI that uses deep learning to accurately replicate human speech. According to the company, in just three months its AI has rapidly expanded from generating only 20 hours of speech in one voice to generating hundreds of hours of speech using hundreds of different synthetic voices. Baidu said that unlike similar TTS neural nets, Deep Voice 2 generates speech in real time, “as fast as it needs to be played.” The company also boasted that the AI can learn from relatively short recordings of many different voice sources. In a paper outlining the methodology behind Deep Voice 2, Baidu explained that this is a major breakthrough for TTS technology. “Most TTS systems are built with a single speaker voice, and multiple speaker voices are provided by having distinct speech databases or model parameters,” the company said in its paper. “As a result, developing a TTS system with support for multiple voices requires much more data and development effort than a system which only supports a single voice.”

"What exactly is dark data? Our connected, digital world is producing data at an accelerated pace: there were 4.4 zettabytes of data in 2013, and that’s projected to grow to 44 zettabytes by 2020, and IBM estimates that 90 percent of the data in existence today was produced in the last two years.

But between 70 and 80 percent of that data is unstructured — that is, “dark” — and therefore largely unusable when it comes to processing and analytics. Lattice uses machine learning to essentially put that data into order and to make it more usable."
Apple acquired Lattice Data, "a company that applies an AI enabled inference engine to take unstructured, 'dark' data and turn it into structured (and more usable) information." According to rumor, the prices was around $200 million.

"Apple buys smaller technology companies from time to time and we generally do not discuss our purpose or plans."

Researchers build artificial synapse capable of autonomous learning

Researchers from France and the University of Arkansas have created an artificial synapse capable of autonomous learning, a component of artificial intelligence. The discovery opens the door to building large networks that operate in ways similar to the human brain. The results were published April 3 in the journal Nature Communications. "People are interested in building artificial brain networks in the future," said Bin Xu, a research associate in the University of Arkansas Department of Physics. "This research is a fundamental advance." The brain learns when synapses make connections among neurons. The connections vary in strength, with a strong connection correlating to a strong memory and improved learning. It is a concept called synaptic plasticity, and researchers see it as a model to advance machine learning. A team of French scientists designed and built an artificial synapse, called a memristor, made of an ultrathin ferroelectric tunnel junction that can be tuned for conductivity by voltage pulses. The material is sandwiched between electrodes, and the variability in its conductivity determines whether a strong or weak connection is made between the electrodes.
