Abstract:
1. A semiconductor integrated circuit device that is used in a speech recognition device that issues a question or a message to a user based on speech reproduction data and performs speech recognition processing on speech of the user, comprising: a scenario setting unit that receives a command designating scenario flow information representing a relationship between a plurality of the speech reproduction data and a plurality of conversion lists, and, in accordance with the scenario flow information, selects prescribed speech reproduction data from among the plurality of speech reproduction data which are stored in a speech reproduction data storage, and selects a prescribed conversion list from among the plurality of conversion lists which are stored in a conversion list storage; a standard pattern extraction unit that extracts a standard pattern corresponding to at least part of individual words or sentences included in the prescribed conversion list, from a speech recognition database containing standard patterns representing a distribution state of frequency components of a plurality of phonemes that are used in a prescribed language; a speech signal synthesizer that synthesizes an output speech signal based on the prescribed speech reproduction data; a signal processor that extracts the frequency component of an input speech signal by performing a Fourier-transform on the speech signal, and generates a feature pattern representing the distribution state of the frequency component of the speech signal; and a match detector that compares the feature pattern generated from at least part of the speech signal with the standard pattern extracted from the speech recognition database, and outputs a speech recognition result.
