We have recently tagged a 300,000 word corpus of spoken French. Strategy
and evaluation and reported here:

Campione, E., Véronis, J., & Deulofeu, J (2005). 3. The French corpus.
In Cresti, E. & Moneglia, M. (Eds.), /C-ORAL-ROM, Integrated Reference
Corpora for Spoken Romance Languages,/ (pp. 111-133). Amsterdam: John
Benjamins.

The good surprise is that we achieved results as good as those we get on
written corpora (ca. 98% precision). This is probably due to the fact
that, on one hand, spoken corpora are more difficult because of
disfluencies (repetitions, repairs, etc.), but on the other hand, their
lexicon is much smaller and sentence complexity much lower.
