Techniques for recommending speechlets to users via voice user interfaces (VUIs) are described. A system may include predetermined rankings of speechlets. The predetermined rankings may be determined offline and may represent reliabilities of the speechlets. During runtime, when the system receives a user input that can be handled by multiple speechlets, the system may determine a type of speechlet configured to handle the user input. The system may also identify information specific to the user's previous interactions with the system. The system may rerank the predetermined rankings using the user specific information, as well as other information. The system may recommend speechlets to the user based on the speechlets' rerankings. The system may first recommend the top reranked speechlet. If the user accepts the recommendation, the system may cause the top reranked speechlet to handle the original user input. If the user declines the recommendation, the system may recommend the next top reranked speechlet to the user. The system may work its way down the rerankings of the speechlets until the user accepts a recommendation, until the system recommends all of the reranked speechlets, or until the user indicates the system should stop recommending speechlets.
