Google Develops AI Model to Decipher Dolphin Communication
The Intricate World of Dolphin Communication
The intricate clicks, whistles, and pulses echoing through the underwater world of dolphins have long fascinated scientists. The dream has been to understand and decipher the patterns within their complex vocalisations.
Google’s Solution: DolphinGemma
Google, collaborating with engineers at the Georgia Institute of Technology and leveraging the field research of the Wild Dolphin Project (WDP), has unveiled DolphinGemma to help realize that goal. Announced around National Dolphin Day, the foundational AI model represents a new tool in the effort to comprehend cetacean communication. Trained specifically to learn the structure of dolphin sounds, DolphinGemma can even generate novel, dolphin-like audio sequences.
The Wild Dolphin Project
Over decades, the Wild Dolphin Project – operational since 1985 – has run the world’s longest continuous underwater study of dolphins to develop a deep understanding of context-specific sounds, such as:
- Signature "whistles": Serving as unique identifiers, crucial for interactions like mothers reuniting with calves.
- Burst-pulse "squawks": Commonly associated with conflict or aggressive encounters.
- Click "buzzes": Often detected during courtship activities or when dolphins chase sharks.
DolphinGemma: The AI Ear for Cetacean Sounds
Analysing the sheer volume and complexity of dolphin communication is a formidable task ideally suited for AI. DolphinGemma, developed by Google, employs specialized audio technologies to tackle this. It uses the SoundStream tokeniser to efficiently represent dolphin sounds, feeding this data into a model architecture adept at processing complex sequences.
The CHAT System and Two-Way Interaction
While DolphinGemma focuses on understanding natural communication, a parallel project explores a different avenue: active, two-way interaction. The CHAT (Cetacean Hearing Augmentation Telemetry) system – developed by WDP in partnership with Georgia Tech – aims to establish a simpler, shared vocabulary rather than directly translating complex dolphin language.
Google Pixel Enables Ocean Research
Underpinning both the analysis of natural sounds and the interactive CHAT system is crucial mobile technology. Google Pixel phones serve as the brains for processing the high-fidelity audio data in real-time, directly in the challenging ocean environment.
Conclusion
Recognizing that breakthroughs often stem from collaboration, Google intends to release DolphinGemma as an open model later this summer. While trained on Atlantic spotted dolphins, its architecture holds promise for researchers studying other cetaceans, potentially requiring fine-tuning for different species’ vocal repertoires.
