Non-fluency features also occur when producing utterances. As people think about what to say during conversations, there are errors and corrections in speech. For example, voiced/un-voiced pauses which are "umm", "erm", etc. in voiced pauses and in transcripts un-voiced pauses are denoted as (.) or (1) relating to the amount of time of the pause. Tag questions are also a part of non-fluency features; these are used by the speaker to check if the listener understands what the speaker is saying. An example is "Do you know what I mean?" False alerts occur when the speaker is voicing an utterance but stops and starts again, usually to correct themselves.
