Recording setups in the field cover all speech recordings performed in the `real world'.4.4The great advantage is - of course - that all environmental features and in most cases even the speaker profiles match exactly the needs of a certain application. However, the costs are much higher and the re-usability is low, because corpora of this kind are usually highly specialized.
Very often field recordings are time-critical in that sense that the location and the speakers are not available all the time. It is worthwhile performing a rehearsal a few weeks before the recording phase to make sure that the recording devices and all procedures work without problems. If you produce the speech corpus as a contractor, we recommend that at least on the first day of the field recording a representative of your client is present.
