Sum: Interdental /l/ Part 2


Interdental laterals also occur in the Italian dialects of Calabria
(M.  Loporcaro e A. Mancuso, Interdentale ma anche laterale: /l/
prevocalica nei dialetti della (Pre)Sila, in P. M. Bertinetto e
L. Cioni (a cura di), Unità fonetiche e fonologiche: produzione e
percezione, Pisa, Scuola Normale Superiore 1998, pp.77-90). Professor
Loporcaro was kind enough to supply a hard copy of the paper, which
can be very briefly summarised as follows: Interdental /l/
(transcribed as IPA voiced (inter)dental fricative symbol edh with
superscript l) has been recorded in three towns (Casole, S. Giovanni
in Fiore, Bisignano) within an area east of Cosenza in Southern Italy
which shows [DH] realisations of Latin singleton /l/ in pre- and
intervocalic positions. The interdental realisation has not been
remarked upon in previous literature.

Loporcaro and Mancuso (1998: 80) describe the articulation as
involving a neutral position of the tongue body, with the tongue tip
protruded between the teeth (they refer to a brushing motion in the
articulation, presumably as the tongue tip is withdrawn). Airflow
occurs on either side of the medial constriction and there is some
light and barely perceptible frication.  Acoustically, interdental /l/
has a low F1 (300-380 Hz) with F2 between 900 and 1050 Hz where
visible. Higher formants are not consistently visible. Frication is
light.

Loporcaro and Mancuso (1998: 81) attribute the low F2 in the
interdental lateral relative to geminate non-interdental /l/ either to
the larger lingual cavity arising from the interdental articulation,
or due to velarisation. The latter explanation is excluded by a
kineasthetic study of one speaker from Casole, but Loporcaro and
Mancuso remark that no detailed articulatory studies have been
conducted. Relatively low F2 provides an acoustic parallel to dark
laterals (cf. American English interdental /l/, the presence of dark
laterals in neighbouring Italian dialects). An acoustic quality of
darkness seems likely to have played a part in the diachronic
development of these sounds, whether the low F2 is attributable to
velarisation/pharyngealisation or to a larger oral cavity (or both).

Interdental /l/ seems to crop up due to coarticulation to interdental
/TH/ in Castillian Spanish (see
http://www.unibuc.ro/eBooks/filologie/spaniola/2.htm#2623), and Jim
Fidelholtz and Rudy (see below) also reported this possibility for
words like 'health'. My own interdental /TH/ (apparently the
minority realisation for British English speakers) coarticulates to my
(dental) /l/, not the other way round.

To conclude: this realisation of /l/ occurs in some people's speech as
an idiosyncrasy, perhaps mainly for dark coda and syllabic /l/'s , and
in Calabrian dialect. It may also occur after speech therapy or as an
exaggerated realisation of /l/. It occurs in Hawai'i and the two
respondents who claimed to use it in 'normal speech' were both from
the West Coast. The possibility that this is a native feature for
Britney Spears and Reese Witherspoon, both from Louisiana, cannot be
discounted. Whether it is a truly regional feature is impossible to
say on the basis of this very limited data, but it could be. It seems
there is much still to learn about this.
