$\bigcirc$ Cross checks of meta information

Cross-check meta information in signal files, meta files and annotation files. For example, the speaker ID could be contained in a NIST SPHERE signal file header, in a SAM label file and in a meta data file describing the speaker characteristics. If they are not all the same for the same recording item, something is wrong. Report deviations caused by upper and lower-case spellings. Do signal files and annotation files have exactly the same `length'^5.5?

These checks can be integrated into the other checks on signal and annotation files by simply looking up the corresponding meta data files.
