The sense and significance of meta data have already been discussed before (see chapter , p. ). It is advisable to include at least the contents - perhaps also the formats - of the meta data files of your speech corpus into the specification because this might be a point of interest for your partners or client.
Basically your specified meta data should reflect more or less the variable parameters in your specifications of the speaker profiles, of the recording setup and the technical specifications. Constant parameters do not need to be included in the meta data because they will already be written into the corpus documentation. However, it might be a good idea to include even such redundant information into the meta data as well with respect to the possibility to browse speech corpora as mentioned before.
