More and more phoneticians, as I do, rely on measures of experience, such as frequency of occurrences, in their investigations. I have been struggling with these for the last three years and ended up with a fairly easy accessible data base of frequencies for word forms and phones and biphones (phonotactic frequencies) for German. It is based on CELEX and the SDEWAC corpus.
The database can be accessed here and a description here. How to cite the database is included in the description. Thanks for sharing and citing.
