1. A voice/non-voice determination device comprising:
processing circuitry configured to:
receive signal data as acoustic signal;
include a first model which receives input of the acoustic signal and outputs acoustic scene information which is information regarding, represented in a sequence of a plurality of vector data, a scene where the acoustic signal is collected and configured to receive input of the acoustic signal and a parameter of the first model learned in advance and output the acoustic scene information;
include a second model which receives input of the acoustic signal and outputs speech enhancement information which is information regarding the acoustic signal after enhancement and configured to receive input of the acoustic signal and a parameter of the second model learned in advance and output the speech enhancement information;
include a third model which receives input of the acoustic signal, the acoustic scene information and the speech enhancement information and outputs a voice/non-voice label which is information regarding a label of either a speech section or a non-speech section and configured to receive input of the acoustic signal, the acoustic scene information, the speech enhancement information and a parameter of the third model learned in advance and output the voice/non-voice label;
include a fourth model which receives input of the acoustic signal and outputs phoneme recognition information which is information regarding a phoneme recognition result of the acoustic signal and configured to receive input of the acoustic signal and a parameter of the fourth model learned in advance and output the phoneme recognition information;
wherein the third model is a model which receives input of the acoustic signal, the acoustic scene information, the speech enhancement information and the phoneme recognition information and outputs the voice/non-voice label;

receive input of the acoustic signal, the acoustic scene information, the speech enhancement information, the phoneme recognition information and the parameter of the third model learned in advance and output the voice/non-voice label; and
cause outputting a result of speech recognition data associated with the acoustic signal according to the voice/non-voice label as output from the third model and the phoneme recognition information as output from the fourth model.
