Just as most smartphone cameras now allow users to focus on a single object among many, it may soon be possible to pick out individual voices in a crowd by suppressing all other sounds, thanks to a new Artificial Intelligence (AI) system developed by Google researchers.
This is an important development as computers as not as good as humans at focusing their attention on a particular person in a noisy environment. Known as the cocktail party effect, the capability to mentally “mute” all other voices and sounds comes natural to us humans.
However, automatic speech separation — separating an audio signal into its individual speech sources — remains a significant challenge for computers, Inbar Mosseri and Oran Lang, software engineers at Google Research, wrote in a blog post this week. In a new paper, the researchers presented a deep learning audio-visual model for isolating a single speech signal from a mixture of sounds such as other voices and background noise.
“In this work, we are able to computationally produce videos in which speech of specific people is enhanced while all other sounds are suppressed,” Mosseri and Lang said. The method works on ordinary videos with a single audio track, and all that is required from the user is to select the face of the person in the video they want to hear, or to have such a person be selected algorithmically based on context.
The researchers believe this capability can have a wide range of applications, from speech enhancement and recognition in videos, through video conferencing, to improved hearing aids, especially in situations where there are multiple people speaking. “A unique aspect of our technique is in combining both the auditory and visual signals of an input video to separate the speech,” the researchers said.
“Intuitively, movements of a person’s mouth, for example, should correlate with the sounds produced as that person is speaking, which in turn can help identify which parts of the audio correspond to that person,” they explained.
The visual signal not only improves the speech separation quality significantly in cases of mixed speech, but, importantly, it also associates the separated, clean speech tracks with the visible speakers in the video, the researchers said. IANS
South Korean game developer has introduced a new initiative for Battlegrounds Mobile India (BGMI) which will enable a new level of parental control via time limitations and OTP confirmation. The 'Game Responsibly' initiative will also show warning messages along with break reminders, game limits and more. "Every player, below the age of 18, needs to register a parent or a guardian before they start playing for the first time. An OTP will be sent to the registered person's number, post which the minor is allowed to play the game," the company said in a statement.
Some games can get intense and make players lose track of time. However, with timely break-time reminders, the developer has made sure players get the required downtime. These reminders will help them look up from their game and get back to real life, maintaining a healthy game-life balance. In addition, with a strict gameplay limit in place players below 18 years must not indulge in gaming for more than 3 hours per day. This automatically helps them treat gaming as an activity performed in moderation.
The brand has also set an in-game daily spend limit of Rs 7,000 that automatically stops them from overspending and overgaming. Krafton recently announced that it has removed 25 lakh accounts in just over a month to eradicate cheating on Battlegrounds Mobile India (BGMI). Since the last announcement, between October 1 and November 10, Krafton banned 25,19,692 accounts permanently and 7,06,319 temporarily. "The company has cleaned out most of the cheaters in the game, making BGMI a much more fun experience, and will continue to take whatever step is necessary to keep BGMI fair and fun," it claimed.

The rise in air pollution, coupled with lousy lifestyle habits, is causing a spike in respiratory diseases. According to a Lancet report, the contribution of chronic respiratory diseases in India increased from 4.5 per cent in 1990 to 6.4 per cent in 2016. With respiratory issues on the rise, there is an increased demand for natural solutions to treat such issues. Instead of conventional medicine, people are turning to alternative medical therapies to find cures for ailments.
Common Lung Disorders
Bronchitis is a health condition that causes inflammation in the airways of the lungs. This leads to narrowing of the air pathways and excess mucus causes wheezing, coughing and difficulty breathing. It is a chronic condition that interferes seriously with daily life.

Chronic Obstructive Pulmonary Disease (COPD)
It is a chronic inflammatory lung disease that obstructs the airflow to the lungs. Symptoms of COPD include breathing difficulty, mucus (sputum) production, coughing, and wheezing. It can result from long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Those affected by COPD are at an increased risk of developing lung cancer, heart disease, and a variety of other conditions.

This is another variation of COPD. Bronchitis causes a similar build-up of mucus that can cause inflammation and coughing. The lungs' airways are constantly inflamed as chronic bronchitis often lasts for months on end. Symptoms of chronic bronchitis include incessant coughing, whistling sounds while breathing, wheezing and a tightening of the chest. It is said that the cure for all ailments is available the natural way. Here are some of the alternative medicine approaches to treat respiratory disorders.

Alternative Medicinal Approaches to Treat Respiratory Disorders
Asthma is one of the most common lung diseases. One of the primary causes of asthma is allergies, which often result from the food consumed. It is crucial, therefore, to first prepare a diet that is suitable for an individual. Often, dairy products, meats, and certain nuts can increase the production of mucus. Foods like these must be avoided. Also, antioxidants can prevent damage resulting from chronic obstructive pulmonary disease. Diet is important in this regard, as fruits and vegetables high in Vitamins A, C, and E can improve the condition of COPD patients.

Yoga and Exercise
Treatment of lung disorders often involves the use of the lungs to promote healthy breathing habits. Exercises like cycling, swimming, yoga etc. that create a need for full capacity breathing are of great importance. Exercising the diaphragm is important and simple activities can go a long way in the treatment of the same. Pranayama, the practice of controlled breathing, is an integral part of alternative treatment for people suffering from respiratory issues. This extensive breathing practice helps to expand the lungs and improve the capacity of the lungs, which helps an individual breathe more freely.

The traditional Chinese practice of acupuncture involves inserting thin needles into the skin to stimulate certain parts of the body. According to a study published in the journal Annals of Allergy, Asthma and Immunology, people with allergic rhinitis who were given acupuncture treatments twice a week for eight weeks had fewer symptoms than those administered placebo.

It is important to remember that no one complementary or alternative therapy works well for everyone with respiratory issues. Therefore, a proper assessment is done before deciding on the approach to the treatment plan. For those considering alternative medicine for their respiratory problems, it is recommended to speak to an expert first and discuss the approach that may work best.

Did you know that over 40-year-olds might lose up to 8 per cent of their muscular mass every decade? After the age of 70, the pace of decrease may double. Sarcopenia, or advanced muscle loss, affects roughly one-third of persons over the age of 50. Muscles are crucial for organ function, skin health, immunity and metabolism, as well as for common physical acts like picking things up, reaching for something, opening a jar or getting out of a chair. To put it another way, keeping muscle mass as you become older is critical to living a happy and healthy life. "Muscle loss is an ageing factor that is rarely discussed, and people accept its signs, such as a loss of strength and energy, as a natural part of ageing," says Ganesh Kadhe, Associate Director Medical and Scientific Affairs at Abbott Nutrition. "However, muscle fitness can often predict how we will age and remain active and independent."

The good news is that you may assist, prevent or delay muscle loss by taking the appropriate precautions. While muscle loss is unavoidable as we age, it does not have to be.
To stay strong as you age, start following the tips below to fuel and keep muscles fit for years to come!
1. Engage in regular exercise, including resistance training, to maintain muscles and strength.
2. Eat good source of protein from lean meats, eggs and beans; aim for 25-30 grams of protein at every meal.
3. Choose a balanced diet full of veggies, fruits, whole grains, proteins, healthy fats and key vitamins and minerals like calcium and vitamin D.
4. Consider taking other muscle health ingredients, like HMB.
5. Talk to your healthcare provider about nutrition, especially if you are ill, hospitalised or recovering from surgery, to manage illness-related muscle loss.
