32 Feature functions

This chapter contains a list of a basic feature functions available for stream items in utterances. See section 14.6 Features. These are the basic features, which can be combined with relative features (such as n. for next, and stream names to follow links). Some of these features are implemented as short C++ functions (e.g. asyl_in) while others are simple features on a stream item (e.g. pos). The following features are defined for all stream items: name, duration, addr, start and end. New features may be defined through Scheme too, these all have the prefix lisp_.

The feature functions are listed in the form Stream.name where Stream is the name of the stream that the function is appropriate to and name is its name. Note that you will not require the Stream part of the name if the stream item you are applying the function to is of that type.
