Name a Data Stream Instance

The general syntax for naming a data stream instance is:

StreamX

where:

Stream is the prefix for the type of data stream.
X is the instance number. The instance number cannot begin with the digit 0. The number is optional–an instance without an assigned number is still treated as unique and different from other instances that have numbers.

For example, w1 represents the instance ‘1’ of the word label stream. f3 represents the instance ‘3’ of the speech frame stream.

This table contains a complete list of the available data stream types.
