Embodiment 1

[0026] Existing pronunciation prediction methods are usually based on G2P conversion. The G2P method converts vocabulary into pronunciation phoneme sequences by establishing a mapping relationship between vocabulary and pronunciation phonemes. Using the G2P method, it is basically possible to accurately obtain the pronunciation phoneme sequence matching the conventional vocabulary, but since this method only uses the mapping relationship between vocabulary (word sequence) and pronunciation phoneme, for some special vocabulary, such as vocabulary containing polyphonic words, The accuracy of pronunciation phoneme sequences matched with vocabulary determined by this method is often low, thus affecting the quality of pronunciation dictionaries.

[0027] In order to solve the problem that the quality of the pronunciation dictionary is affected because the prior art cannot accurately predict the correct pronunciation of the vocabulary, Embodiment 1 of the present application provides...

Embodiment 2

[0088] In order to solve the problem of low accuracy of pronunciation phoneme sequences matched with vocabulary by adopting the prior art, an embodiment of the present application provides a pronunciation dictionary construction device. The structure schematic diagram of this vocabulary pronunciation prediction device is shown in Figure 3, mainly comprises the following functional units:

[0089] The decoding unit 21 is used to input the speech acoustic features of the target vocabulary into the speech recognition decoder; wherein, the pronunciation dictionary in the speech recognition decoder includes: the target vocabulary and the candidate pronunciation phoneme sequence of the target vocabulary;

[0090]Pronunciation determination unit 22, for determining the probability distribution of the target vocabulary corresponding to the output candidate pronunciation phoneme sequence according to the speech recognition decoder output candidate pronunciation phoneme sequence with the...

Abstract

The invention discloses a method of constructing a pronouncing dictionary, so as to solve the problem that the quality of the pronouncing dictionary constructed according to the prior art is poor. The method comprises steps: acoustic-phonetic features of a target vocabulary are inputted to a phonetic recognition decoder, wherein the pronouncing dictionary in the phonetic recognition decoder comprises the target vocabulary and a candidate pronouncing phoneme sequence of the target vocabulary; according to the candidate pronouncing phoneme sequence outputted by the phonetic recognition decoder, the possibility distribution of the target vocabulary corresponding to the outputted candidate pronouncing phoneme sequence is determined; according to the possibility distribution, correct pronouncing phoneme sequence for the target vocabulary is selected from the outputted candidate pronouncing phoneme sequence; and according to the correct pronouncing phoneme sequence, the pronouncing dictionary is constructed. The invention also discloses a device for constructing the pronouncing dictionary.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for constructing a pronunciation dictionary. Background technique [0002] Voice interaction technology began to appear as early as the middle of the 20th century. In recent years, with the popularization of smart phones, a large number of voice interaction products have appeared one after another, and voice interaction products have entered the daily life of ordinary users. For example, the voice input method receives and recognizes the user's voice, and then converts the user's voice into text, which saves the cumbersome input of typing; , the identity of the caller can be known. [0003] In the voice interaction technology, the pronunciation dictionary is an important part of the voice interaction system and a bridge connecting the acoustic model and the language model. Its coverage and pronunciation quality have a significant impact on the ove...
