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
- 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
- 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,
- 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.
