During the study at Queen’s University, the researchers changed the vowel sounds that the participants heard over headphones as they talked. They found that while the adults and young children changed their vowel sounds in response to this altered feedback, the toddlers did not.
“We were very surprised to find that the two-year-olds do not monitor their own voice when speaking in the same way as adults do,” says Ewen MacDonald, a former Queen’s research associate and now associate professor at the Technical University of Denmark. "As they play music, violinists will listen to the notes they produce to ensure they are in tune. If they aren't, they will adjust the position of their fingers to bring the notes back in tune. When we speak, we do something very similar. We subconsciously listen to vowel and consonant sounds in our speech to ensure we are producing them correctly.”
The researchers have proven that toddlers use a different strategy to control speech than adults. They still have not pinpointed the exact method children under two use when learning to control speech. Future studies are being developed to determine what strategy toddlers are using.
“Understanding the development of speech is a complex and challenging problem. Using novel techniques, such as the ones used in this experiment, we can isolate and better understand how the different components of speech develop,” says Dr MacDonald. One possibility is that toddlers rely on the interaction with the person they are talking to in order to judge the accuracy of their speech sounds.
Other researchers on the study include Queen’s psychology professor Kevin Munhall and Elizabeth Johnson, an assistant professor in the department of psychology at the University of Toronto.
The research was recently published in Current Biology.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
