While populations may wax and wane, it is rare for an entire population to be replaced by a completely different set of individuals. We document the large-scale relocation of cultural groups of sperm whale off the Galápagos Islands, in which two sympatric vocal clans were entirely replaced by two different ones. Between 1985 and 1999, whales from two clans (called Regular and Plus-One) defined ...

Listeners can explicitly categorize unfamiliar talkers by regional dialect with above-chance performance under ideal listening conditions. However, the extent to which this important source of variation affects speech processing is largely unknown. In a series of four experiments, we examined the effects of dialect variation on speech intelligibility in noise and the effects of noise on percept...

Many local or regional dialects exist in China. In case of mismatch between the dialect used to train the system and the dialect of the user, poor recognition accuracy is obtained. In this paper, we therefore investigate the development of a dialectspecific recognition system in Mandarin Chinese using standard adaptation techniques: a speaker-independent (SI) model trained on a source dialect (...
