Acoustic and auditory properties of r were examined in nine Swedish dialects. The sounds were produced in intervocalic position by several upper middle aged male speakers. Approximant r variants outnumbered fricatives and taps. Trills occurred just marginally. Acoustical analysis of the approximants suggested a fair amount of overlap between dialects in the F2/F3 space, but some dialects were relatively well separated. Auditorily, four place categories (prealveolar, postalveolar, retroflex and back) could be discerned fairly reliably. These were separated to some extent in the F2/F3 space, but retroflex and back r could not be separated solely in terms of F2 and F3. This acoustic similarity may contribute to explaining the notorious articulatory variability of r.
