Multi-space distribution for pattern recognition based on mixed continuous and discrete observations

摘要

Performing speech recognition on a tonal language is done using a plurality of tonal models. Each tonal model has a multi-space distribution and corresponds to a known syllable in a language. A first data stream indicative of an observation of an utterance is received. The observation has both a discrete and a continuous tonal feature. A second data stream indicative of spectral features of a syllable of an utterance is also received. The first data stream is compared against at least one of the plurality of tonal models and the second data stream is compared against a spectral model.
