# Create Speaker Classifiers

(Applies to the IDOL Speech Server component.)

To perform speaker identification and segmentation in IDOL Speech Server, you must create and optimize speaker templates for each speaker that you want to identify, and create speaker classifier templates. The Create Speaker Classifier wizard in the Control menu takes you through this process.

The `AddTask` and `WavSidOptimize` actions perform these tasks. For more information on speaker templates, see the IDOL Speech Server Administration Guide and the IDOL Speech Server Reference.
