At present, in the process of speech recognition research, it is found that the speech database established by adults cannot well understand children’s speech, and many problems exist in recognition errors.
Because children’s language has different voice and language characteristics from adults due to its voice and articulation, children’s speech recognition has natural technical difficulties. In addition, children are not good at interacting with machines in a way that they can understand. Whether it is a more friendly interface or a more intelligent voice assistant, the recognition effect is not satisfactory.
In order to solve this problem, Nexdata has developed over 10,000 hours children speech data. It’s is recorded by children, and the recording contents conforms to the characteristics of children’s speech.
