# Spo

The Speaker ID Optimization (.spo) file to write or read.

You can specify an absolute or relative file path. If you specify a relative path, it is considered as being relative to the speaker ID directory. If the file path is excluded, HPE IDOL Speech Server defaults to the temporary directory.

Note: The SpeakerIDDir parameter in the `[Paths]` section of the configuration file sets the location of the speaker ID directory.

- The StreamSidOptimize and WavSidOptimize tasks write to the file. Depending on the value of the SpoAppend parameter, each time the task is run, HPE IDOL Speech Server either writes to a new file or appends to a common file (HPE IDOL Speech Server creates the common file if it does not already exist).
- The SidPackage tasks reads the file. If you have multiple .spo files, set the SpoList and SpoPath parameters instead of the `Spo` parameter.
