Reproducibility assurance procedures

   

Reproducibility means the ability to reproduce a signal under the same conditions. The requirement of ensuring the reproducibility of speech recordings can, above all, be motivated by the following factors:

• For speech database production:
  • to enable adequate data selection for a specific task (i.e. for evaluation of speech recognisers ) from a huge pool of different speech corpora, based on a complete specification of the speech recordings, and
  • to enable future extensions of the database (i.e. with different speakers or languages).

• For the production of speech data to be exploited as test stimuli in speech assessment procedures:
  • to ensure that the tests may be repeatable with similar data for reasons of extension or verification,
  • to ensure that the test results may be interpretable correctly, considering all information about source and channel  characteristics, and
  • to allow making comparisons with experimental results gained from other test procedures. 

These two goals of common database production and test stimuli generation are not further differentiated. While in Section 8.7.1 some features are suggested to describe the recording conditions, standardised methods and data are proposed in Section 8.7.2.
