    摘要: A system and method for speaker independent speech recognition is provided that integrates spectral and tonal analysis in a sequential architecture. The system analyzes the spectral content of a spoken syllable, or group of syllables, (18) and generates a spectral score for each of a plurality of predicted syllables (46, 22). Time alignment information (36) for the predicted syllable(s) is then sequentially passed to a tonal modeling block (14) which performs an iterative fundamental frequency contour estimation for the spoken syllable(s). The tones of adjacent syllables, as well as the rate of change of the tonal information, is then used to generate a tonal score for each of the plurality of predicted syllables. The tonal score (34) is then arithmetically combined with (40) the spectral score (32) in order to generate an output prediction.

    摘要: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for identifying entities that are related to an entity to which a search query is directed. One of the methods includes receiving a search query, wherein the search query has been determined to relate to a first entity of a first entity type, and wherein one or more entities of a second entity type have a relationship with the first entity; receiving search results for the search query; determining that a count of search results identifying a resource containing a reference to the first entity satisfies a first threshold value; determining that a count of search results identifying a resource having the second entity type as a relevant entity type satisfies a second threshold value; and transmitting information identifying the one or more entities of the second entity type as part of the response to the search query.
