Waveform Truncation

If a waveform file was truncated due to a recording error by the system or by the failure of the speaker to press the record button at the proper times, the following notation in the corresponding transcription file was used:

• Beginning of utterance truncation:

      ~ TRANSCRIPTION

• End of utterance truncation:

      TRANSCRIPTION ~

• Beginning and end of utterance truncation:

      ~ TRANSCRIPTION ~

• Null waveform

      ~~

In the final corpus, null waveforms have been discarded.
