REU Site: Animal Language Processing and Understanding
What animals are talking about is a fascinating research topic. Previous work in bio-acousitics studied a handful of species and has suffered from limited scale and high cost. Furthermore, no previous research has attempted to adopt a systematic approach to associate animal vocal sounds with written symbols, and meanings like we do with human languages.
Our REU Site projects are based on the leading hypothesis that animal languages are similar to human languages to some degree, including that the languages of animals evolve through their interaction with other creatures and that animals are able to express their unique feelings to the outer changes of surroundings by differentiating their sounds. Considering this, two hypotheses are put forward:
Structural Similarities to Human Language: We hypothesize that animal communication may possess structures akin to human language, including phonemes, lexicon, and syntax, indicating the presence of a language-like system.
Contextual Semantics: We propose that animals employ consistent communication patterns in specific contexts, reflecting semantics. This suggests that animal vocalizations are associated with distinct activities or intentions.
In our preliminary study, we have built a pipeline (see above figure) of acquiring dog videos from YouTube, cleaning and segmenting the audio and video tracks of the animals, and transcribing the vocals into a sequence of predefined phonetic symbols. Based on this pipeline, the undergraduate participants of REU site will make two research thrusts: i) to collect high quality, partially annotated multimedia animal communication data; and ii) to experiment on this data using our animal language processing pipeline to gain insights about the language of a new species.
To achieve these goals, we will recruit student animal lovers with computing or biology backgrounds. Each year, participants will spend 10 weeks away from UTA learning the basics and collecting data on a part-time basis (Phase 1), and 10 weeks summer full-time at UTA doing experiments, validating their findings and improving the pipeline (Phase 2). Our work eventually will develop into an open-source web-based animal language study platform called AniVoice.
