A New AI Can Focus on One Voice in a Crowd
When you are listening to someone in a crowd, you can tune out any background noise to hear that one particular person. A new AI was developed and it has the possibility of picking up one voice in the crowd in order to hear one particular person.
Humans are particularly good at focusing on one specific voice, a phenomenon that’s known as the cocktail party effect. However, programs designed to pick up and list one specific speaker in a noisy environment have struggled to mimic a human’s ability to focus on one voice. The new AI created is designed to use both visual and audio cues, such as mouth movements in order to separate sounds produced by other speakers.
Researchers at Google recently tested their AI on video clips that featured two or multiple people talking over each other. The levels of background noise were various. The new AI was able to distinguish which sounds are coming from which speaker and they were more accurate than a previous algorithm that used only audio.
The AI will be presented in August at the 2018 SIGGRAPH meeting in Vancouver. This type of AI could be helpful to virtual assistants to hear voice commands in a noisy environment.
Scientists Discovered a New Part of Sperm that Could Explain Infertility
The concentration of sperm per ejaculation has been getting lower in the past few years. However, scientists have created an artificial version of sperm that could one day replace regular sperm.
Many things in our environment have a great impact on a quality of sperm, including common household products that we use daily.
According to a new study, we discovered a completely new sperm structure which can be partially responsible for infertility and birth defects. The centriole is a structure placed in the cytoplasm of a cell that has a great effect on cell division. Researchers from the University of Toledo found that there is a second centriole in sperm with a lot of unusual properties. Although the first and second centrioles have the same function they look completely different.
Tomer Avidor-Reiss, from the University of Toledo, Department of Biological Sciences said:
“Abnormalities in the formation and function of the atypical centriole may be the root of infertility of unknown cause in couples who have no treatment options available to them. It also may have a role in early pregnancy loss and embryo development defects.”
Scientists believe that you need two centrioles to make the centrosome working. Still, we can’t get too ahead of ourselves, thinking the other structure can cause fertility.
