In this paper we focus on the construction of the minimal deterministic finite automaton S k that recognizes the set of suffixes of a word w up to k errors. We present an algorithm that makes use of S k in order to accept in an efficient way the language of all suffixes of w up to k errors in every window of size r, where r is the value of the repetition index of w. Moreover, we give some experimental results on some well-known words, like prefixes of Fibonacci and Thue-Morse words, and we make a conjecture on the size of the suffix automaton with mismatches.
