Truncated waveforms

If a speech signal file is truncated due to a recording error, the following notation is to be used:

Beginning of utterance truncation: ~transcription
End of utterance truncation: transcription~
Beginning and end of utterance truncation: ~transcription~

There is a difference between an utterance which is truncated and is now incomplete, but which has not damaged the initial or final words, and an utterance when word(s) have been damaged. The ~ indicates truncation of the word it is attached to. Otherwise truncated but good utterances will not be marked in any way.

Note: The tilde symbols ``~'' must not be separated from the truncated word by a white space (different from the ATIS convention).
