In general, I would not suggest using the output of another AI or CV model as an identification for iNaturalist observations if it isn’t based on your own expertise. iNat asks for observations to be based on user’s own knowledge/experience. For the iNat CV, this input is denoted in the observations, and identifiers can take this into account, but this isn’t the case for other machine learning approaches. There are other discussions about this approach on the forum in relation to Merlin as well.
If you do use another machine learning approach and use its suggestion as your own ID, please be explicit about the process in your notes/descriptions. Other machine learning approaches can definitely generate erroneous suggestions in many cases.
Additionally, as @lappelbaum noted, you should not post spectrograms as images (even though they can be helpful for IDs). Each image on iNat needs to contain the organism observed. One important reason for this rule is that images are used for training the CV model, so including spectrograms could lead to errors in the CV model. You could post external links to an image hosting service like imgur or others if you want identifiers to have access to a spectrogram.
