A University of Washington team has developed an artificial intelligence system that lets a user wearing headphones look at a person speaking for three to five seconds to “enroll” them. The system, called “Target Speech Hearing,” then cancels all other sounds in the environment and plays just the enrolled speaker’s voice in real time even as the listener moves around in noisy places and no longer faces the speaker.

The team presented its findings May 14 in Honolulu at the ACM CHI Conference on Human Factors in Computing Systems. The code for the proof-of-concept device is available for others to build on. The system is not commercially available.

“We tend to think of AI now as web-based chatbots that answer questions,” said senior author Shyam Gollakota, a UW professor in the Paul G. Allen School of Computer Science & Engineering. “But in this project, we develop AI to modify the auditory perception of anyone wearing headphones, given their preferences. With our devices you can now hear a single speaker clearly even if you are in a noisy environment with lots of other people talking.”

To use the system, a person wearing off-the-shelf headphones fitted with microphones taps a button while directing their head at someone talking. The sound waves from that speaker’s voice then should reach the microphones on both sides of the headset simultaneously; there’s a 16-degree margin of error. The headphones send that signal to an on-board embedded computer, where the team’s machine learning software learns the desired speaker’s vocal patterns. The system latches onto that speaker’s voice and continues to play it back to the listener, even as the pair moves around. The system’s ability to focus on the enrolled voice improves as the speaker keeps talking, giving the system more training data.

The team tested its system on 21 subjects, who rated the clarity of the enrolled speaker’s voice nearly twice as high as the unfiltered audio on average.

This work builds on the team’s previous “semantic hearing” research, which allowed users to select specific sound classes — such as birds or voices — that they wanted to hear and canceled other sounds in the environment.

Currently the TSH system can enroll only one speaker at a time, and it’s only able to enroll a speaker when there is not another loud voice coming from the same direction as the target speaker’s voice. If a user isn’t happy with the sound quality, they can run another enrollment on the speaker to improve the clarity.

The team is working to expand the system to earbuds and hearing aids in the future.

Instructions on the practice: What to do? / How to practice?

Copy the movements! In each final position use any type of power to tense the body and make the posture become strong. It’s no problem to use muscle power in the beginning!

Stay in each posture and slowly deep breath! (Full inhalation – Full exhalation) Minimum should be around 4 breathing cycles (any number above is perfectly fine). 

Try to keep the power / strength in each posture steady, regardless of in- or exhalation. Keep Focus and direct your intent in the proper direction.

For what should I aim for? / What is the goal of the practice?

Easy is: Do it for the pleasure of doing it!

Useful is: Make the postures become more powerful / stronger by every week!

Purposeful is: Observe and become aware of your transformation.

The names of the postures are:

ENGLISH / GERMAN:

Opening · 00:00

1) Pressing up to the Heavens / Beide Hände in den Himmel pressen · 01:30

2) Drawing the Bow / Den Bogen spannen · 02:40

3) Separating Heaven and Earth / Himmel und Erde spalten · 05:05

4) Wise Owl gazes backwards / Die weise Eule starrt zurück · 06:55

5) Big Bear turns from Side to Side / Der große Bär bewegt sich von Seite zu Seite · 08:50

6) Touching the toes and bending backwards / Die Zehen berühren und nach hinten beugen · 11:40

7) Clenching fists with an angry gaze / Die Fäuse ballen und grimmig Schauen · 13:25

8) Stretching the body / Den Körper dehnen · 18:40

Closing · 20:05

Why are there so many variations of this routine?

Practicing without clear intent is useless, no matter which form you choose.

This video is one of the more simple forms that I practice. Easy to remember, clear to execute.

You want more beautiful variations, go ahead. But understand the purpose of simplicity first.

Hill’s concept of “Positive Mental Attitude” (PMA). It is a cornerstone of his philosophy on personal development and success, as outlined in his various works, including the famous book “Think and Grow Rich.” PMA is about maintaining an optimistic, constructive outlook on life, which Hill believed was crucial for achieving one’s goals and overcoming challenges. Here are the key aspects of this concept:

Hill considered a Positive Mental Attitude to be the starting point of all success. He believed that success doesn’t necessarily begin with knowledge, skills, or talent, but with the mindset one adopts. A Positive Mental Attitude shapes how individuals perceive challenges and opportunities. It influences not just thought processes but also actions, leading to more constructive and proactive behaviors. PMA involves not just the presence of positive thoughts but also the absence or management of negative ones. Hill emphasized the importance of controlling one’s mind to prevent negative thoughts from taking root and overshadowing positive ones. Hill was a proponent of the idea that a positive mindset can attract positive outcomes, a concept similar to the Law of Attraction. He believed that by expecting success and maintaining a positive outlook, individuals could draw favorable circumstances and opportunities toward themselves. A Positive Mental Attitude contributes to resilience, enabling individuals to persist in the face of setbacks and failures. Hill argued that setbacks are often stepping stones to success and that a positive attitude helps in navigating through them. Hill also noted that a positive attitude not only benefits the individual who practices it but also positively influences those around them. This can lead to better relationships, more effective leadership, and a more supportive network. Just like the Cosmic Habit Force, Hill believed that a Positive Mental Attitude could be developed and strengthened through habit. Regularly practicing positive thinking and actions reinforces this attitude.

Orcas* live in small pods. Within these family groups they communicate with one another using their own sound dialects. With the help of artificial intelligence, scientists are now looking for repeated patterns which would indicate that orcas have a language model.

A team of researchers headed by Professor Elmar Noeth and Rachael Cheng from the University of Erlangen-Nuremberg spent three years collecting data on the movements and vocalization of various orca pods in the Pacific. Their aim was to investigate a possible connection between the patterns of the orcas* calls and their behavior. Using special microphones, they captured the underwater sounds and behaviors of these marine mammals. Then they tried to determine the orcas* position and classify their calls. It’s a first step towards solving the mysteries of whale song.

Using artificial intelligence to decipher unfamiliar communications systems is not without its difficulties. However, it’s already clear that AI will transform our ideas about highly communicative species in the coming years.

His World Wireless System had the potential to advance technology by nearly a century, while also providing free energy to the globe. Unlike so many of his era, Tesla did not work for financial gain, instead working to advance humanity. Perhaps it is not surprising that a man so far ahead of his time has only found his place in the 21st century, an age shaped by his technological brilliance.
