Description
Technical Field
The present application relates to the field of data analysis technologies, and in particular, to a method and a system for analyzing and processing sentences.
Background
Reading is an important learning method in language learning: the reading can improve the accuracy and the fluency of the pronunciation of the learner and the comprehension capacity of the learner on the sentences and even chapters, thereby strengthening the correct use of the rhythm characteristics such as the stress reading, the intonation and the like.
In reading aloud, the learner may experience the following errors or inaccuracies: mispronunciations or impracticalities of words (including vowels, consonants, syllable boundaries, accents, continuations, transcription savers, etc.), intraword and interword disfluences (including inappropriate durations and pauses), prosodic changes (omission or misuse of accents) such as lack of pitch capability, lack of correct grammatical and semantically related intonation changes (e.g., intonation or precipitation at the end of a sentence), inability to correctly understand a sentence and control the rhythm of speech output by phrases (Phrasing).
Currently, more traditional schemes practice reading aloud in two ways:
the first method is as follows: talking dictionary
A standalone electronic dictionary device, or desktop software, software running in a mobile device (including WeChat applets, web pages, etc.). After a user queries a word, the voiced dictionary provides a traditional paraphrase of the word, along with audible audio (live voice or computer synthesized language) of the pronunciation of the word that can be played. The learner learns the pronunciation of the word by playing the audio and may orally mimic it. The voiced dictionary may also provide a number of word-related illustrative sentences, which may also be accompanied by audio that may be played.
The second method comprises the following steps: talking book
The audio file can be an independently distributed audio file (mp3, etc.), a matching optical disk of a book, an early recording tape, or a program form on a certain content platform: such as PodCast, himalayan FM, wechat, public, etc. The way learners use audiobooks is usually "listening". The learner can also imitate by himself.
The third method comprises the following steps: pronunciation evaluation software
Including software running on a desktop system, software running on a mobile device (mobile applications, wechat applets, web programs, etc.), and other smart devices running an operating system (smart televisions, smart speakers, etc.). Such software typically provides demonstration audio that compares the learner's spoken speech to the demonstration speech to produce an overall score, and typically also provides scores for the segmentation dimensions including pronunciation accuracy, completeness, and fluency.
Although the scheme can guide the user to read aloud, the first and second modes cannot evaluate the reading level of the user, and the learner cannot get immediate feedback;
in the third mode, although the training of the readers can be scored, only sentence-level reading scoring can be provided, and the system cannot realize the targeted training of the learner on the structural segment; and the mode only provides recorded demonstration audio and cannot provide a teaching function, so that the user's grasp of reading skills is reduced.

Detailed Description
The technical solutions of the present invention are described in detail with reference to the drawings and the specific embodiments, and it should be understood that the embodiments and the specific technical features in the embodiments of the present invention are merely illustrative of the technical solutions of the present invention, and are not restrictive, and the embodiments and the specific technical features in the embodiments of the present invention may be combined with each other without conflict.
First, the terms to which the present invention relates are explained:
the sentence: sequences of words and punctuation, organized according to grammatical rules and semantic requirements, express specific meanings, usually ending with punctuation.
And (3) voice: human vocal organs (vocal cords, vocal tract, tongue, mouth, lips, teeth) naturally convert a specific sentence into sound in the form of a sequence of phonemes under the coordination of the brain.
Rhythm: for the expression needs in human natural language, specific phones/syllables are assigned different prosodic parameters: duration (Duration), Pitch (Pitch), Energy (Energy), and Pause (Pause) to produce a "twitch-down, twitch-down" effect. Humans can perceive whether prosodic parameters match text.
Tone: refers to the trend of the pitch trajectory of the pronunciation of a sentence or a segment of a sentence. In general, statement sentences and special interrogations use down-tones, while general interrogations use up-tones.
Semantic rereading: unlike the repeated reading of symbols (stress) in english words, speakers often make the prosody of some words more prominent in peripheral words according to the semantic and expression requirements of sentences, such as increased pitch, increased energy (volume), increased duration, additional pause, and so on.
The grammar structure is as follows: the process of parsing the sentence described by the natural language text into a syntax tree describing the aforementioned components according to the linguistic criteria, such as main, predicate, object, predicate, shape, complement. The syntax tree is usually represented as a nested structure, e.g., S ═ NP + VP, meaning that a sentence S is composed of a name phrase (as subject) plus a verb phrase (as predicate).
The rhythm structure is as follows: the prosodic structure is a process of reorganizing a text sequence into an 'interconnected block structure' according to the communication requirement during the speaking process of a speaker. The correct and proper prosodic structure can reduce the communication cost of a speaker and a listener. The prosodic structure affects the prosodic features of the text after it is read. This block-like structure also has nested (hierarchical) junctions
However, the structure is much shallower than the grammar structure, and generally has only 2-3 layers. For example: S-IP 1+ IP2, IP 1-PP 1+ PP2 indicate that a sentence S is composed of two intonation phrases IP1 and IP2, where IP1 is composed of a prosodic phrase PP1 and a prosodic phrase PP 2.
Fig. 1 shows a statement analysis processing method according to an embodiment of the present invention, where the method includes:
s1, performing prosody hierarchy analysis on the exercise sentences to determine the chunk time boundary of each prosody chunk in each sentence;
first, the prosodic hierarchy needs to be analyzed, and in the embodiment of the present invention, the prosodic hierarchy can be divided into 3 layers: sentence layer (S), intonation phrase layer (IP), prosodic phrase layer (PP). One S may be composed of one to several IPs, one IP may also be composed of one to several PPs, and the marks between the chunks are chunk time boundaries.
Specifically, S ═ w0,w1,w2,,,wi,,,wn]Is divided intoThe results of the precipitated hierarchy are: s [ [ w ]0,w1,w2][[w3,w4],[wi,,,wn]]Wherein the sentence S includes two IPs: IP1 ═ w0,w1,w2]，IP2＝[w3,,,wi,,,wn]Wherein IP2 contains two PPs, namely: PP1 ═ w3,w4]，PP2＝[wi,,,wi,,,wn]。
Before performing prosodic hierarchy analysis on an exercise sentence, word time boundaries of individual words in the sentence need first be determined. In the embodiment of the present invention, the word time boundary is: IP _ Boundary, PP _ Boundary, None-Boundary.
For example, the statement is: this is a serous issue and sensing well with discussh Moscow. The word time boundaries for each word are shown in table 1:
TABLE 1
The time boundaries of the individual prosodic chunks in the sentence can be determined based on the time boundaries of the words. For example, the statement is: this is a serous issue and sensing well with disc with Moscow. When the learner reads the sentence with 12 words and 17 syllables, the learner needs to avoid completing the pronunciation at one stroke, but the learner should accord with the characteristics of the sentence to make proper analysis and planning of the prosodic structure.
Thus, after prosody hierarchy analysis, the prosody analysis results are shown in fig. 2, where the complete exercise sentence is divided into corresponding hierarchies in fig. 2.
It should be noted that, in the embodiment of the present invention, the prosodic hierarchy analysis may be calculated and solved by using a machine-learned algorithm model such as a conditional random field algorithm, a hidden markov model, a recurrent neural network, or the like.
Through the prosody level analysis, the prosody levels in the voice can be marked, and the prosody levels can be used for evaluating the voice exercise of the user and used as a scoring basis for subsequent voice exercise.

and S4, taking the determined chunk time boundary, the intonation marks and the practice sentences with the repeated reading marks as standard prosody level sentences.
After the intonation analysis of the exercise sentence is completed, the exercise sentence also needs to be re-read and analyzed, that is, a re-read mark of each word segment in the speech is marked, wherein the re-read type is shown in table 4:
| type of rereading | Is suitable for | Rereading situation |
| None | Common to the null word, or weakened real word | Weak reading |
| Normal | Common to real words | Is normal |
| Emphasized | The real word is required for highlighting the semantic meaning | Rereading |
TABLE 4
Based on the contents in table 2, the label set of the rereading is: e ═ None, Nor mal, alpha sized }; for each word in the training data, one label in the set E needs to be labeled, and the training data set D ═ D0,D1,,,Di,,,,Dk}, wherein: di＝Si,Ai,TiRepresenting one document (sentence) in the training set;
Si＝[wi0,wi1,,,wij,,,win]a sequence of words (Token) representing the document (sentence), length being; a. thei＝[ai0,ai1,,,aij,,,ain]Representing a sequence of acoustic features (Acoustics features) corresponding to each word (Token); t isi＝[ti0,ti1,,,tij,,,tin|tij]Where E denotes a tag sequence corresponding to each word (Token).
