• The incredible discovery was made in London
Who would have thought that the singing of birds and human conversation between them have something in common. An incredible discovery was made in London. British researchers, based on the program of recognition of human speech, created a brand new, purpose of which is now recognition of birds' voices.
Special devices, recording birdsong could be in operation for several days. And, what is most remarkable is the fact that the singing of each individual can be recognized individually. Recognize the voice of the singer feathered possible in the case, even if his solo merges with the general chorus! Thanks to this powerful recording system installed in an open space, scientists, ornithologists managed to collect over the past years, literally the whole ocean acoustic recordings. But in practice it turned out that people find it very difficult to understand all of these archives. The new program is computer software, developed and perfected by the University of London Queen Mary, would automatically recognize the voices of birds.
And it would be of great help in monitoring the amount of the individual birds. Dan Stouel, a scientist who was one of the first involved in this research, pointed out that the automatic distribution of the sounds made by birds, is very useful. For it is thus possible to know exactly how much and what kind of birds are found in this region. Also during the research it was found that the methods used previously to recognize human speech turned out to be perfectly suited for working with bird voices. After the singing of birds has much in common with the human voice, in spite of the fact that the evolution of these two groups took place independently of one another. And then, it will help to better understand and to understand how it developed human speech, as well as how to build an organization of animals in the group. Previously developed by ornithologists program demanded by the introduction of human bird trills frequency size. In contrast to the previous one, the new program will distinguish birds by analyzing existing databases that have been made and distributed to scientists. The software itself is currently determines the analysis will be conducted on what criteria.
For example, the rapid surge or drop in the frequency of bird songs. This wonderful program is equipped with the ability to recognize bird songs, which are contained in archival sound recordings of the British Library. This led to participation in an open international competition for recognizing voices of birds. The victory of the creators of the program and ornithologists was deserved. Recognition accuracy birdsong in the percentage was 85.4% and secured the second place. Currently, researchers are bird voices engaged in improvement of the program, making it a new record to the next competition to enter the prize-winning first place!
