+    cepsclustering(cc::AbstractMatrix, k::Integer)
+
+Perform clustering of cepstral coefficients using k-medoids algorithm.
+
+!!! note
+    This function can be used only after importing the `Clustering` package.
+
+# Arguments
+- `cc::AbstractMatrix`: A matrix of cepstral coefficients.
+- `k::Integer`: Maximum number of clusters to be examined (to find the optimal number of clusters).
+
+# Returns
+- A vector of vectors, where each vector contains the indices of the cepstral coefficients in \
+  the corresponding cluster.
