Previous studies on the perception of language prosody and dialectal prosody have shown that languages and regional dialects can be identified by prosodic cues alone. This pilot study tests this for 4 Swiss German dialects. 70 participants were presented with filtered speech material devoid of segmental cues. The filter was applied for frequencies between 250 Hz.7000 Hz. Despite this filtering, 3 of 4 dialects were recognized by the participants. Identification rates were considerably higher for dialects which present distinct prosodic features, in this case relatively slow speech rate in one instance and high pitch range in the other.
