Mit ( Massachusetts institute of technology ) has just developed a low-power chip designed for automatic speech recognition. The most outstanding feature of this chip is that it can reduce the power consumption of speech recognition by 99 %.
 
Regarding this function of this chip, foreign media gave extremely high evaluation, saying that this chip can make voice commands almost everything. ( foreign media title: new chip couple voice command to almost anything ) although some exaggeration, this progress is still very exciting.
 
Now, we are more and more used to talking with our equipment instead of operating it manually. Amazon echo and Google home have both achieved great success in the market. Siri, apple's voice assistant, is also widely used ( no way, apple's mobile phone sales are too large ). Voice recognition devices are everywhere. Mit researchers believe that voice recognition technology is the trend in the future, which encourages them to make a decision to make such a low-power chip.
 
Researchers at MIT said that compared with common products on the market, this chip will save 99 % energy. The power consumption for speech recognition on a typical mobile phone is about 1 watt, while the power of this chip is as low as 0.2 - 10 milliwatts. In this way, the endurance of related devices will be greatly improved.
 
If such a chip can be mass produced and commercialized, its application range will be very broad.
 
Besides mobile phones, wearable devices will also use speech recognition extensively. Because of this, the problem of narrow interaction interface of wearable devices will be solved. A team led by Anan tha chandrakasan, professor of electrical engineering and computer science at MIT, developed the chip. he said: " voice input will become a natural interface for many wearable applications and intelligent devices. "
 
There will also be a large number of voice equipment used in the internet of things. Baidu's chief scientist Wu enda once said that voice recognition will push forward the revolution of the internet of things, including automotive interfaces, household equipment, and wearable devices. However, the internet of things has always been worried about excessive energy consumption. the emergence of energy-saving chips is also a rigid demand for the development of the internet of things.
 
How does this chip save energy?
 
First, it will conserve energy. It will judge whether it is noise or not by detecting the surrounding sound. only when it is determined that someone is actually talking to the device will it start the energy. However, the common speech recognition chip will always run a neural network in the background to detect all kinds of sounds, whether it is human voice or noise, which will release energy.
 
Secondly, it compresses data and reduces power consumption by evaluating only a small portion of audio in onboard memory at a time.
 
Marian ver helper, a professor of microelectronics at the Catholic university of Leuven in Belgium, is also studying how to make equipment and sensors more efficient. He thinks: " for the next generation of mobile and wearable devices, it is very necessary for speech recognition to run at ultra-low power consumption. Because the trend of miniaturization of equipment is very obvious. "
 
Since the power consumption of this chip is very low, it can make the battery smaller, expand the endurance and reduce the size of the device at the same time.
 
If ultra-low power chips can realize large-scale commercial use, the expectation of " let voice command everything" may one day become a reality.
