Claim 12:
13. A non-transitory, computer-readable medium containing instructions that, when executed by at least one processor of a system for processing a speech signal, cause the system to perform operations comprising:
obtaining a speech signal;
generating, using the speech signal, a first sequence of feature vectors;
selecting, from the first sequence of feature vectors, a second sequence of m*n consecutive feature vectors;
generating a third sequence of n intermediate vectors by applying the second sequence to a first neural network model, each intermediate vector corresponding to a subsequence of m consecutive feature vectors in the first sequence;
generating a fourth sequence of n average probability vectors by applying each of the n intermediate vectors to a corresponding second neural network model; and
determining the phones in the second sequence using the fourth sequence of n average probability vectors.
