… Andrea Ravignani Proposal (250 words): Introduction: Language emerges from iterated learning: generations learn then teach the next generation. Over generations, speech patterns and pronunciation can change, especially in multilingual environments where dialects may form. Temporal and acoustic structures can emerge from this process. We examine whether the sound systems of languages can emerge from this process when speech sequences are learned by participants, then reproduced by following generations. Native speakers of English, German, Hindi, and Chinese have been recorded speaking nonsense sentences in several emotions. We examine how subsequent … subsequent generations and adapt to the native language of the speaker. We also expect that the individual’s prior exposure (i.e., culture) will determine how much features converge or diverge. Setting and Methods: The method uses iterative learning whereby the speech reproductions of one generation becomes the stimuli for the next generation. Acoustic features are extracted from speech recordings and we test how the distribution of various acoustic features changes over generations. Time series …
