Google DeepMind built DolphinGemma, a version of its system trained on dolphin and whale sounds.

True if, by 23 July 2025, Google DeepMind (alone or with partners such as Georgia Tech and the Wild Dolphin Project) had built DolphinGemma, a Gemma-based model trained on recordings of dolphin and whale sounds. Mostly true if DolphinGemma exists and was built by Google DeepMind but its training data were dolphin sounds only, with no whale sounds, or Google DeepMind's role was shared with others. Mixed if a model named DolphinGemma exists but Google DeepMind's involvement or the training on cetacean sounds is substantially different from the claim. Mostly false if the model was built mainly by others, with only minor involvement from Google. False if no such model existed by that date.

Set before the research began.

   “Trained extensively on WDP’s acoustic database of wild Atlantic spotted dolphins, DolphinGemma functions as an audio-in, audio-out model”

   “Enter DolphinGemma. Developed by Google, this AI model makes use of specific Google audio technologies: the SoundStream tokenizer efficiently represents dolphin sounds”

   “While trained on Atlantic spotted dolphin sounds, we anticipate its potential utility for researchers studying other cetacean species, like bottlenose or spinner dolphins.”

   “Today, on National Dolphin Day, Google, in collaboration with researchers at Georgia Tech and the field research of the Wild Dolphin Project (WDP), is announcing progress on DolphinGemma: a foundational AI model trained to learn the structure of dolphin vocalizations and generate novel dolphin-like sound sequences.”

Georgia Tech's independent news release (E4) confirms that by April 2025 Google had announced DolphinGemma, a foundational AI model trained on dolphin vocalizations. It describes the work as a collaboration with Georgia Tech researchers and the Wild Dolphin Project. Google's announcement (E2) says Google developed the model. It also says the model was trained on the Wild Dolphin Project's recordings of Atlantic spotted dolphins and does not mention whale sounds. So the model existed and Google had the central role in building it, but the training data appear to be dolphin-only and the work was shared with partners, which fits the 'mostly true' criterion.
