Research framework operationalizes hypotheses on pre-lexical vocal communication, suggesting new measurement methodologies.

This research aims to establish a framework for testing hypotheses regarding the nature of pre-lexical human vocal communication.
Developed the V-O framework for operationalizing hypotheses in vocal communication.
Introduced linked inference architectures: PLVCR and ABEN for modelling vocal capacities and constraining behaviours.
Incorporated various types of evidence, including archaeological and genetic data, to guide hypotheses.
V-O framework allows for measurement and comparison of diverse vocal communication hypotheses.
Establishes reproducibility and auditability in the research process.
Facilitates empirical testing of hypotheses related to vocal systems and their evolution.
