This chapter describes the activities at the core of every speech corpus production: the actual recording of the speech signals. Most of the technical and and other advice you've already found in the previous chapter. In the following we summarize some more practical hints that might be useful during the actual collection phase. Basically these hints can be structured into Ongoing Documentation, Pre-Validation, Quality Control, Data Pipelining and Recruitment. The order of the sections in this chapter are not meant to be chronological. You should read them all before you start the collection.
