Specific embodiment
In order to enable the object, technical solutions and advantages of the present invention become apparent, root is described in detail below with reference to accompanying drawings According to example embodiments of the present invention.Obviously, described embodiment is only a part of the embodiments of the present invention, rather than this hair Bright whole embodiments, it should be appreciated that the present invention is not limited by example embodiment described herein.Based on described in the present invention The embodiment of the present invention, those skilled in the art's obtained all other embodiment in the case where not making the creative labor It should all fall under the scope of the present invention.
When language rhythm Boundary Prediction scheme described herein is predicted based on content of text with voice broadcasting content of text Language rhythm boundary position.The front end text-processing for the application scenarios such as the program can be used for speech synthesis, video generates In.The information such as corresponding speech pause can be provided according to varigrained rhythm boundary position, voice is enable correctly to express language Justice improves the natural and tripping degree that voice plays, with the voice of outputting high quality.
The rhythm is the concept of an Auditory Perception, it is the necessary means of language communication, hearer can be helped to more fully understand Information entrained by voice.Have in rhythm Boundary Prediction and text and closely contact, in order to improve the nature that voice plays Degree, needs to obtain the relevant information of more rhythms from text, for example, varigrained rhythm boundary position.
By taking Chinese language as an example, the rhythm boundary of usual Chinese is divided with prosody hierarchy.The prosody hierarchy of Chinese is generally main It is divided into three basic units: rhythm word (Prosodic Word, PW), prosodic phrase (Prosodic Phrase, PPH) and language It adjusts phrase (Intonational Phrase, IPH), and the relationship between them is according to tree-shaped level knot on the rhythm Structure arranges in an orderly manner.These three basic units also respectively represent the corresponding granularity of rhythm boundary demarcation.One intonation phrase can With comprising one or more prosodic phrases, a prosodic phrase may include one or more rhythm words.Therefore, intonation phrase Granularity is maximum, and the granularity of rhythm word is minimum, and the granularity of prosodic phrase is between intonation phrase and rhythm word.That is, this The granularity of three basic units is ascending to be followed successively by rhythm word, prosodic phrase and intonation phrase.
Specifically, by taking text " prediction of main research rhythm structure herein " as an example, it itself can be used as an intonation Phrase.The text can be two prosodic phrases by rhythm boundary demarcation: " main research herein " and " prediction of rhythm structure ". Further, the text can by rhythm boundary demarcation be 6 rhythm words: " this paper ", " main ", " research ", " rhythm ", " structure " and " prediction "., it is apparent that the granularity of intonation phrase is greater than the granularity of prosodic phrase, the granularity of prosodic phrase It is greater than the granularity of rhythm word again.
In the following, the present invention carrys out descriptive language rhythm Boundary Prediction method by taking Chinese as an example, it should be understood that this is only exemplary rather than Limitation of the present invention.Language rhythm Boundary Prediction method can be also used for other language, such as English, Japanese and German etc..
Currently, rhythm Boundary Prediction is usually by the Task-decomposing of Chinese rhythm Boundary Prediction granularity at PW, PPH and IPH tri- A varigrained independent task, modeling is handled respectively.Fig. 1 shows the language rhythm Boundary Prediction model of the prior art Schematic block diagram.As shown in Figure 1, the language rhythm Boundary Prediction model of the prior art includes feature extraction layer 110, task layer 120 and 130 three parts of result output layer.Feature extraction layer 110 is used to extract the embedded feature of text.Task layer 120 is used for The embedded feature extracted based on feature extraction layer 110 predicts varigrained task rhythm side by multiple component models respectively Boundary.As a result output layer 130 exports final rhythm Boundary Prediction result based on the varigrained task rhythm boundary predicted.
Task layer 120 may include multiple component models, and different component models are respectively used to predict varigrained task Rhythm boundary.As shown in Figure 1, task layer 120 may include first assembly model 121, the second component model 122, third component Model 123, and so on, and may include N component model, wherein N is integer, such as can be equal to 4.It is appreciated that Although including being more than 3 component models in task layer 120 shown in Fig. 1,2 or 3 groups can also be wherein only included Part model.These component models are respectively used to predict varigrained rhythm boundary, thus complete varigrained prediction task. In order to distinguish with final rhythm boundary, the rhythm boundary that each component model is predicted is known as task rhythm boundary.Often A component model is independently completed the prediction task of corresponding granularity, does not have dependence between component model.For example, task layer 120 multiple component models can be respectively completed any one prediction task among tri- granularities of PW, PPH, IPH, first assembly Model 121 can complete PW prediction task, and the second component model 122 can complete PPH prediction task, third component model 123 It can complete IPH task.
Based on the task rhythm boundary that multiple component models are predicted, the final rhythm boundary of text can be exported.
In above-mentioned language rhythm Boundary Prediction model 100, for predicting the component on varigrained task rhythm boundary Model is all independent from each other each other.Each receives the feature of text respectively, is then based only upon the received feature of institute and completes The prediction task of oneself.This mode has ignored the dependence between the task rhythm boundary of each granularity, makes the language rhythm The effect of Boundary Prediction is had a greatly reduced quality.
In order at least be partially solved the above problem, the embodiment of the present invention provides a kind of language rhythm Boundary Prediction method. In the language rhythm Boundary Prediction method, varigrained prediction task is unified in a frame using multi-task learning framework Under.The identical input data of each prediction task carries out Unified Characterization and shares between task.In addition to this, for predicting difference It can establish dependence between the component model on the task rhythm boundary of granularity.Particularly, for predicting appointing for higher granularity The component model on business rhythm boundary is also appointed based on what the component model for predicting the task rhythm boundary of lower granularity was predicted Rhythm boundary be engaged in complete the prediction task of oneself.Fig. 2 shows the language rhythm according to an embodiment of the invention boundary is pre- The schematic flow chart of survey method 200.As shown in Fig. 2, the described method comprises the following steps.
Step S210 extracts the embedded feature of text.
It include all word contents that carry out language rhythm Boundary Prediction in text.It " is mainly ground herein with text below Study carefully the prediction of rhythm structure " for illustrate the language rhythm Boundary Prediction method 200.
Embedded methods are the methods for indicating discrete variable with vector row.Embedded feature is to utilize embedded methods will Original discrete objects are converted to vector row and a kind of vector representation for exporting.Embedded feature captures original object Built-in properties, to measure the similitude of object according to the similitude in vector space.It is appreciated that extracting the insertion of text Formula feature can preferably be used for the input of machine learning, for example, being used for feedforward neural network (Feed forward Neural Network, FNN) and/or multilayer feedforward neural network (Multilayer Feed forward Neural Network, MFNN input).
In one example, the character level feature of text can first be extracted.For example, can extract first the Chinese character of text, The various features information such as the long, distance of participle, part of speech, word.It is appreciated that different character level features can according to need progress spirit Adjustment living, such as increase or delete etc..The character level characteristic use embedded methods are then based on to extract to obtain text Embedded feature.
Step S220 is utilized respectively each of at least two component models part model and is based on the prediction pair of embedded feature Answer the task rhythm boundary of granularity, wherein at least one component model predict the task rhythm boundary of corresponding granularity be also based on to The task rhythm boundary of few other assemblies model prediction, at least one described component model are more at least one other than described The granularity on the task rhythm boundary that component model is predicted is big.
The component model can be the model for being used to predict rhythm boundary of any existing or following research and development, the application It is without limitation.For example, the component model can be with two-way long short-term memory-condition random field (Bidirectional Long Short-Term Memory-Conditional Random Field, BLSTM-CRF) based on modeled and It obtains.
It is appreciated that the component model at least 2, different component models are for predicting the varigrained task rhythm Boundary.Different component models can be based on identical or different mathematical model.All component models are shared step S210 and are mentioned The embedded feature taken.
In all components model, at least one component model predicts that the task rhythm boundary of corresponding granularity is also based at least The task rhythm boundary of one other assemblies model prediction.In other words, the two component models are not independent, on the contrary Ground establishes therebetween certain dependence or incidence relation.It is built on the whole for task rhythm Boundary Prediction in this way Mould, avoid causes language rhythm Boundary Prediction integrally to be imitated because having ignored dependence between varigrained task or incidence relation The problem of fruit declines.In short, a part of component model is based only upon the embedded feature of text in the technical solution of the embodiment Predict the task rhythm boundary of corresponding granularity.The members model includes the task rhythm boundary for predicting minimum particle size Component model.Another part component model is based not only on embedded feature also the appointing based on the prediction of other assemblies model of text Business rhythm Boundary Prediction corresponds to the task rhythm boundary of granularity, and for each of described another part component model, The task rhythm boundary that the component model is predicted is bigger than the granularity on the task rhythm boundary that it is based on.Generally, big granularity Task rhythm boundary must be small grain size task rhythm boundary.Still with text " prediction of main research rhythm structure herein " For, the rhythm boundary of the prosodic units of larger granularity is in two prosodic phrases: " herein main research " and " rhythm structure it is pre- Survey " between.And the position is also the rhythm boundary of the rhythm word of smaller particle size, i.e. rhythm word: between " research " and " rhythm " Boundary.So predicting the task rhythm boundary of larger granularity based on the task rhythm boundary of smaller particle size, can be improved larger The accuracy on the task rhythm boundary of granularity.
Fig. 3 a shows the task layer 320a of language rhythm Boundary Prediction model 300a according to an embodiment of the invention Schematic block diagram.Task layer 320a predicts different grains by N number of component model for the embedded feature of text based respectively The task rhythm boundary of degree.N number of component model includes first assembly model 321a, the second component model 322a, third assembly mould Type 323a ... N component model.Wherein N is the integer greater than 1.These component models share the embedded feature of text.
The granularity on the task rhythm boundary predicted according to the component model of the sequence in Fig. 3 a from left to right is gradually increased. That is the granularity on the task rhythm boundary of the second component model 322a prediction is greater than the task rhythm of first assembly model 321a prediction The granularity on boundary, and so on, it is pre- that the granularity on the task rhythm boundary of N component model prediction is greater than (N-1) component model The granularity on the task rhythm boundary of survey.
Appointing in the task layer 320a and language rhythm Boundary Prediction model 100 in language rhythm Boundary Prediction model 300a Being engaged in, there are following differences for layer 120.First assembly model 121, the second component model 122, third component model in task layer 120 123 and N component model be independent from each other.The second component model 322a, third component model in task layer 320a 323a and N component model etc. are the component models that can rely on its left side.
Specifically, in the task layer 120 of language rhythm Boundary Prediction model 100, the input of each component model is only wrapped Include the feature of the text of the output of feature extraction layer 110.
Unlike, in the task layer 320a of language rhythm Boundary Prediction model 300a, the second component model 322a's is defeated Enter in addition to the embedded feature including text, can also include the task rhythm boundary of first assembly model 321a prediction.Such as figure Shown in 3a, the input of N component model can also include the N component model left side in addition to the embedded feature including text The task rhythm boundary of all components model prediction, such as task rhythm boundary, (N-2) of the prediction of (N-1) component model The task rhythm boundary of task rhythm boundary ... ... the first assembly model 321a prediction of component model prediction.It is appreciated that the The input of N component model can also include either one or two of N component model left side or more in addition to the embedded feature including text The task rhythm boundary of a component model prediction.In this way, the second component model, third component model ... and N component model With other assemblies model foundation dependence or incidence relation.
Although it is appreciated that showing the second component model, third component model ... and N assembly mould in above-mentioned example Type is all with its respective all components model foundation on left side dependence or incidence relation, but this is not necessarily.For example, second group Each of part model, third component model ... and N component model component model, can with its respectively the left side one There are dependences between a or a few components model.In other words, the input of the component model includes the embedded of text The task rhythm boundary of the members model prediction on feature and its left side, rather than all components model prediction on its left side Task rhythm boundary.
Fig. 3 b shows the task layer of language rhythm Boundary Prediction model 300b in accordance with another embodiment of the present invention The schematic block diagram of 320b.In the component model in the task layer 320b of language rhythm Boundary Prediction model 300b, not group There are dependences all between its respectively all components model on the left side for part model.Such as the input of third component model 323b The task rhythm boundary of embedded feature and the second component model 322b prediction including text, but third component model 323b Input do not include first assembly model 321b prediction task rhythm boundary.
Although it is appreciated that showing the second component model, third component model ... and N assembly mould in above-mentioned example Type is all with other assemblies model foundation dependence or incidence relation, but this is also not necessarily.For example, can be in the second assembly mould There are a few components model among type, third component model ... and N component model, in a few components model Each there are dependences between its respectively at least one component model on the left side.In other words, a few components Model input include text embedded feature and its respectively the left side at least one component model prediction task rhythm side Boundary.
Fig. 3 c shows the task layer of the language rhythm Boundary Prediction model 300c of further embodiment according to the present invention The schematic block diagram of 320c.The task layer 320a and language rhythm Boundary Prediction model of language rhythm Boundary Prediction model 300a The function of the realization of the task layer 320c of 300c is similar with position, and details are not described herein.Unlike, language rhythm Boundary Prediction In component model in the task layer 320c of model 300c, and not all component model is all between the component model on its left side There are dependences.Such as second component model 322c input only including text embedded feature without include first assembly The task rhythm boundary of model 321c prediction.But the input of third component model 323c is in addition to the embedded spy including text Sign further includes the task rhythm boundary of the second component model 322c prediction.
Step S230, at least based on the task in addition to the task rhythm boundary that at least one other component model is predicted Rhythm boundary determines final rhythm boundary.It is appreciated that in this step, based at least one dependent on other assemblies model The task rhythm boundary that component model is predicted determines final rhythm boundary.
In one example, the final rhythm boundary can be obtained by merging the task rhythm boundary of multiple and different granularities ?.For example, final rhythm boundary can be first assembly model 321c, third component model 323c ... again by taking Fig. 3 c as an example The task rhythm boundary mergence predicted with N component model is resulting.
It is alternatively possible to merge the task rhythm boundary of all granularities of text, to determine the final rhythm boundary of text. For example, final rhythm boundary can be first assembly model 321a, the second component model 322a, third group again by taking Fig. 3 a as an example The task rhythm boundary mergence for the correspondence granularity that part model 323a ... and N component model are predicted respectively is resulting.
It is appreciated that each component model can obtain the task rhythm boundary of corresponding granularity.For some angle, Varigrained task rhythm boundary can independently indicate the rhythm boundary of text.For the same text, granularity is big The position on task rhythm boundary can be less, and comparatively, the position on the small task rhythm boundary of granularity can be more.Still with aforementioned text For this " prediction of main research rhythm structure herein ", the position according to the boundary of prosodic phrase granularity is one, in the rhythm Between phrase " main research herein " and " prediction of rhythm structure ".Boundary position according to rhythm word granularity is 5, is existed respectively Between rhythm word " this paper ", " main ", " research ", " rhythm ", " structure " and " prediction ".Merge the task rhythm of all granularities Boundary may include more rhythm boundary informations, and thus identified final rhythm boundary is more preferable.
Alternatively, final result can be the task rhythm boundary of any one higher granularity or based on the higher granularity What task rhythm boundary determined, predict that the task rhythm boundary is based not only on the embedded feature of text also based on lower granularity Task rhythm boundary.For example, final rhythm boundary can be the task rhythm that N component model is predicted again by taking Fig. 3 b as an example Boundary, wherein N component model is predicted pair based on the task rhythm boundary that (N-1) component model of lower granularity is predicted The task rhythm boundary answered.
It is appreciated that final rhythm boundary can be used for the application such as speech synthesis.
Above-mentioned technical proposal is respectively used to predict that the component model on varigrained task rhythm boundary is united at least two One carries out language rhythm Boundary Prediction under a frame, improves prediction effect.
In one example, the embedded feature that above-mentioned steps S210 extracts text includes following sub-step.
Sub-step S211, segments text, to obtain character level feature.
The various characters grade features such as Chinese character, participle, part of speech, word length and distance can be obtained by segmenting to text.These Character level feature, which can according to need, to be adjusted flexibly, such as is increased or deleted one or more.
In order to handle conveniently, various character level features can be respectively expressed as to solely hot (one-hot) type feature, that is, used One-hot coding.The one-hot coding is to be encoded using N bit status register to N number of state, each state There is its independent register-bit, and when any, wherein only an efficient coding, the coding are to convert class variable A form of process for being easy to utilize for machine learning algorithm.
Character level feature is carried out the processing of feature insertionization by sub-step S212.
The processing of feature insertionization can carry out dimensionality reduction to character level feature.For example, for literal dictionary, Chinese characters in common use are general In 5000 to 10000 scales, therefore the dimension of the one-hot vector of Chinese character is also probably 5000 to 10000.It can use insertion Change feature of the processing by one-hot ocra font ocr grade Feature Conversion for low latitudes.
Now handled with the feature insertionization of the one-hot ocra font ocr grade feature according to an embodiment of the invention by Chinese character For be described in detail sub-step S212.For example, the feature insertionization processing result of Chinese character can be determined according to the following formula:
EMBcc=X1×Ncc×WNcc×Dcc+Bcc,
Wherein, EMBccCharacter level feature for the Chinese character handled through feature insertionization, X1×NccFor the one-hot type of Chinese character Character level feature, Ncc are dictionary size, and Dcc is insertion dimension, and W, B are model parameter.Model parameter can be according to correlation circumstance It is adjusted.For example, carrying out random initializtion before model training, model ginseng is carried out according to loss function in the training process Number adjustment.
In one example, the model for realizing step S212 can be feedforward neural network.
Similarly, the feature insertionization processing knot of other character level features such as participle, part of speech, word length and distance can be obtained Fruit, details are not described herein.
Sub-step S213 connects all character level features handled through feature insertionization, to obtain connection features.
It can feature insertionization place long to the Chinese character, participle, part of speech, the word that are obtained by connection sub-step S212 and distance It manages result and obtains connection features.The connection features include the information of all features of text.
Sub-step S214 extracts the embedded feature of the text based on the connection features.
Based on the connection features that sub-step S213 is obtained, feature can be reinforced by a full Connection Neural Network of multilayer It extracts, to obtain the embedded feature of the text.It is alternatively possible to using multilayer feedforward neural network (Multilayer Feedforward Neural Network, MFNN) complete sub-step S214.MFNN can be using tanh function as activation Function.Alternatively, it using convolutional neural networks (Convolutional Neural Network, CNN) or two-way can also follow Other neural fusions such as ring neural network (Bidirectional Recurrent Neural Network, B-RNN).
Fig. 4 shows the feature extraction layer 410 of language rhythm Boundary Prediction model 400 according to an embodiment of the invention Schematic block diagram.As shown in figure 4, in feature extraction layer, obtain the character level feature of text first, for example, Chinese character, participle, Part of speech, word length and distance etc..These character level features are separately input in feedforward neural network, to carry out feature insertionization place Reason.The character level feature handled through feature insertionization is connected through connector, thus to obtain connection features.Finally, utilizing MFNN base The embedded feature of text is extracted in connection features.
