1. A computer implemented method for language model adaptation for a navigational speech interface comprising:

  • receiving a word lattice resulting from an automatic speech recognition process applied on a speech input received from a user via the navigational speech interface, wherein the word lattice includes a respective speech recognition score for each word in the word lattice;

    adapting a language model comprising a plurality of location entities based on a mobility relevance and a search relevance of the plurality of location entities to the user;

    initiating a re-scoring of said each word in the word lattice using the adapted language model; and

    generating a speech recognition output for the speech input based on the re-scored word lattice.
