Device, method and system for generating utterance verification critical value

The invention discloses a device, a method and a system for generating an utterance verification critical value. When an identification target to be processed is determined, a suggest clinical value can be obtained according to the expected utterance verification effect, and besides, extra collection for linguistic data and training model can be avoided. The method comprises the following steps: firstly, calculating one or more numerical data corresponding to at least one speech unit; secondly, when at least one speech unit sequence is received, receiving the numerical data corresponding to each speech unit in the speech unit sequence and combining the numerical data into the numerical distribution corresponding to the speech unit sequence; and finally, generating a suggest clinical valueaccording to the expected utterance verification effect and the numerical distribution and outputting the suggest clinical value.
