In this paper the method used to implement the so-called F0mod strategy is presented. The F0mod strategy corresponds to a cochlear implant processing strategy based on the clinical ACE strategy, introducing additional pitch cues when voiced speech is detected. After the development and validation of the F0mod prototype, F0mod was implemented on a real-time platform and then tested in cochlear implantees. As an example of the validation process, the evaluation of the F0-extractor used in the model is presented. Results of the speech perception evaluation using sentence in noise tests in Dutch are presented as well.
