swirec_waveform_logging_index_digits

The number of digits used in filenames when Recognizer saves waveform files.

Value

One of these integers: 2, 3, 4.

Default

2 (limit of 99 files per session)

How to set

In Management Station set on the Nuance recognition service. If not using Management Station, set in a Recognizer configuration file (User-nrsxx.xml).

Usage

Occasionally used to expand the number of possible log files written by a single application.

Performance

The only cost is the disk space for any files that remain on the system after the call. In addition, there are more files for any file transfer, log merging, and cleanup operations.

Indirectly, this parameter determines how many utterances can be saved for a single session.

When saving waveforms during a session, the Recognizer increments digits in the filenames. For example:

NUAN-14-28-host-mmm-utt01-PLAYABLE.wav
NUAN-14-28-host-mmm-utt02-PLAYABLE.wav
NUAN-14-28-host-mmm-utt03-PLAYABLE.wav

By default, two digits defines a limit of 99 waveforms during the session. After writing utt99, the counter restarts at 01 and overwrites the first files. Setting this parameter to 3 defines a limit of 999 waveform files. A value of 4 is seldom needed.

Another way to control usage of the index digits is to set swirec_waveform_logging_uniform_name.
