20220314 The recognise command can verify if a speaker matches a previously enrolled voice. Three audio samples are required to enrol a voice. The same passphrase is said for each of the four samples and the phrase must be chosen from a set of supported passphrases.
For this command the three samples are provided to the model and the fourth will be verified. The output consists of a result which is one of Accept or Reject and a score which is a measure of the similarity with a range 0-1. The Accept or Reject response is a result combining both the speaker verification result and speech recognition result, while the similarity score only measures the voice similarity.
