Recording mode

The RECORDING MODE defines the exact method of controlling transfer of speech samples to the storage medium. It is defined in terms of the TAKE, SEGMENTS and SPEECH FILES. It is concerned with the stopping and starting of the sampling process and the way the recording system treats any possible speaking errors.

MODE 1
A TAKE is recorded in one complete SEGMENT, errors are not excised.
(Explanation - this means that the sampling and transfer process is started at the beginning of the TAKE, all the acoustic signal, including breath noise, speaking errors are recorded and the sampling and transfer process is only stopped at the end of the TAKE.)

MODE 2
A TAKE is recorded in one complete SEGMENT, except when a speaking error is detected during the TAKE, and then that error is excised from the storage medium. If there have been no speaking errors there will be no DISCONTINUITIES in the SPEECH FILE. For each section of speech removed due to a speaking error there will be one DISCONTINUITY.

MODE 3
A TAKE is recorded in a number of SEGMENTS. There will be one SEGMENT per utterance, and speaking errors will be included in the SPEECH FILE.
(Explanation - in general this means that an endpoint detector is used to start and stop the sampling and transfer process. Apart from the ``back-off'' time no inter-utterance acoustic signal will be stored in the SPEECH FILE.)

MODE 4
A TAKE is recorded in a number of SEGMENTS. Speaking errors will be excised from the storage medium, and so there will be one SEGMENT per required utterance. This MODE is the same as MODE 3 except that the resulting file will contain no errors.
