< example two >
Fig. 3 is a flowchart of a voice quality inspection method according to an embodiment of the present invention, and as shown in fig. 3, the method according to the embodiment includes:
s3100, obtaining conversation voices of two parties in conversation, and converting the conversation voices into text data.
In this embodiment, the two parties to the call include a first party and a second party, the first party sends the access voice to the second party, and the second party returns the feedback voice to the first party based on the access voice. For example, the first party is a service person, for example, an outbound person in a call-out service, and the second party is a service object in the call-out service.
Accordingly, conversational speech includes: the method comprises the following steps that access voice sent to a second party by a first party and feedback voice returned to the first party by the second party according to the access voice sent by the first party.
Among other things, speech conversion techniques may be employed to convert conversational speech into text data.
S3200, performing keyword matching processing on the text data to obtain a keyword matching result; and performing text similarity calculation on the text data to obtain a similarity calculation result.
And S3300, obtaining a quality inspection report of the dialogue voice according to the keyword matching result and the similarity calculation result.
Carrying out weight assignment processing on the keyword matching result and the similarity calculation result to obtain a quality inspection model, and calculating an output result of the quality inspection model; if the output result is larger than the preset threshold value, the output quality is qualified; and if the output result is not greater than the preset threshold value, outputting that the quality inspection is unqualified. The preset threshold value can be set according to experience, the quality inspection model is a linear model related to the keyword matching result and the similarity calculation result, the quality inspection model comprises a first weight corresponding to the keyword matching result and a second weight corresponding to the similarity calculation result, and the first weight and the second weight can be set according to business requirements.
And matching the similarity calculation result obtained by calculation with the keyword matching result, for example, giving a weight to the similarity calculation result and the keyword matching result, wherein the weight can be adjusted according to the actual condition of the service, and the quality inspection is carried out on the dialogue voice based on the final result after assignment. Therefore, the dialogue voice with high similarity and high keyword matching score can be marked as qualified data, the dialogue voice with low similarity and low keyword matching score can be marked as qualified data, the dialogue voice with high similarity and low keyword matching score can be marked as data needing further judgment, and when the dialogue voice is marked as needing further judgment, the dialogue voice can be judged according to the service requirements. For example, when the customer service telemarketing content basically meets the standard speech technology requirement but lacks some key speech technologies, such as forgetting to ask about the client about the subscription time, acceptable price range, and other key speech technologies, the embodiment may determine that the speech of the section needs to be further determined.
In the embodiment, after the matching degree of the text data of the dialogue voice and the keywords is calculated, the similarity between the text data of the dialogue voice and the standard dialogues is calculated, and whether the dialogues of the customer service are approximately consistent with the standard dialogues is judged by using the similarity instead of judging whether the customer service utters the sentences required in the dialogues according to the keywords appearing in the text, so that quality inspection errors caused by language habits of the customer service staff and the clients in quality inspection only by means of keyword retrieval are avoided. According to the embodiment, the keyword retrieval and text similarity calculation are combined to perform voice quality inspection, and compared with a single keyword retrieval quality inspection mode, errors can be reduced, errors existing in voice quality inspection are reduced, and further labor cost and time cost of enterprises are reduced.
< example three >
The embodiment also provides a voice quality inspection method. With reference to fig. 4, the performing text similarity calculation on the text data in step S3200 to obtain a similarity calculation result further includes:
firstly, performing word segmentation processing on text data to obtain word segmentation of the text data; and performing word segmentation processing on the text data to obtain word segmentation of the text data. For example, the word segmentation process of "here is the outbound team" can obtain three components of "here/this/outbound team". And (4) completing conversational detection according to the obtained participles, namely whether necessary keywords of the conversational speech are spoken in the marketing process. Then, calculating the occurrence frequency of each participle in the text data, and calculating the text quantity of each participle in the preset corpus; and finally, calculating the similarity between the text vector and the text vector of the standard dialect text according to the frequency and the text number of each word segmentation, and taking the calculated similarity value as a similarity calculation result.
In one example, a TF-IDF (Term Frequency-Inverse document Frequency) may be used for text similarity calculation. Wherein, TF refers to the frequency of word occurrence in a text, and generally TF is the number of times of word occurrence in the text/the number of all words in the text; IDF refers to the number of documents in the corpus in which a word appears, and the number of documents is logarithmized, for example, IDF is log (total number of texts in the corpus/number of different texts in the corpus in which a word appears).
The principle of TF-IDF is: the more frequently a word appears in a text, the more important it is for the text; the more texts the word appears, the less the word has strong distinction degree to the article, the smaller the weight in the document is, and the inverse of the word frequency is generally adopted. Also consider a phenomenon, the number of times that some common words appear may be tens of times or hundreds of times of the low frequency words, if it is only a simple inversion process, the weight of the common words will change very little, and the weight of the rare words will appear too big. In order to balance the weight relation between common words and rare words, logarithm operation is adopted for inverse operation.
Comparing the text data with the standard dialogues by the TF-IDF word frequency similarity calculation method to obtain the vector similarity of the text data and the standard dialogues, wherein the larger the similarity value is, the more the content of the call is matched with the standard dialogues, and the smaller the content of the call is otherwise.
For example, the present embodiment constructs a bag-of-words model TF _ IDF (t, d) × IDF (t) for calculating the similarity based on the TF-IDF algorithm.
Similarity between the text vector and the text vector of the standard dialect text is then calculated based on the bag-of-words model. Specifically, with speech a: "i like watching tv and dislike watching movie", voice B: "i do not like watching tv nor watching movie" is exemplified.
The speech A 'i like watching TV and dislike watching movie' is segmented, and the obtained segmentation result is as follows: i/like/watch/tv, not/like/watch/movie; the speech B 'i do not like watching TV nor watching movie' is segmented, and the obtained segmentation result is as follows: i/no/like/watch/tv, and also/no/like/watch/movie.
The corresponding dimensionality of the two voice word segments is as follows: i like, watch, tv, movie, not, too.
Therefore, the word frequency corresponding to each participle in the statistical speech A is as follows:
and voice A: i 1, like 2, watch 2, tv 1, movie 1, not 1, also 0.
And B, voice B: i 1, like 2, watch 2, tv 1, movie 1, not 2, also 1.
The vector data corresponding to the voice A and the voice B obtained through statistics is as follows:
and voice A: [1,2,2,1,1,1,0]
And B, voice B: [1,2,2,1,1,2,1]
Obtaining the speech A and speech B pairAfter the corresponding vector data, the TF (t, d) value of each participle in the speech A can be calculated, and then based on a formula
Figure BDA0002376332310000071
Calculating the IDF (t) value of each participle in the speech A, and substituting the TF (t, d) value and the IDF (t) value obtained by calculation into the bag-of-words model to calculate the similarity between the speech A and the text vector of the standard conversational text.
In this embodiment, the two parties of the call include a first party and a second party, and in the voice quality inspection, if it is required to determine whether the keyword necessary for the call operation is spoken in the marketing process, the conversation voice corresponding to the first party needs to be determined. Thus, the access voice of the first party in the dialogue voice can be acquired, and the access voice can be converted into the first text data. Correspondingly, keyword matching processing and text similarity calculation are respectively carried out on the first text data, and a keyword matching result and a similarity calculation result are obtained.
Taking the call between the outbound person A and the client B in the electricity sales outbound service as an example, the method can acquire the dialogue voice between the outbound person A and the client B from the recording file, convert the dialogue voice into text data, at the moment, the text data comprises first text data corresponding to the outbound person A and second text data corresponding to the client B, perform keyword matching processing and text similarity calculation on the first text data, acquire a keyword matching result and a similarity calculation result, input the keyword matching result and the similarity calculation result into a quality inspection model, and judge whether the voice call is qualified or not by using an output result of the quality inspection model.
In some embodiments, after the access voice is converted into the first text data, word segmentation processing may be further performed on the first text data to obtain word segmentation of the first text data; and performing sensitive word retrieval on the participles, and outputting unqualified quality inspection when the sensitive words exist in the retrieved participles.
Referring to fig. 4, after performing word segmentation processing on the first text data corresponding to the first party, performing keyword search on the processed word segmentation, outputting unqualified quality inspection if sensitive words, such as sensitive words like abusive words, are retrieved, and marking the unqualified reason in the quality inspection report as "the sensitive words occur" so as to complete alarm pushing based on the unqualified mark in the quality inspection report.
In some embodiments, feedback speech of a second party in the conversation speech may be obtained, the feedback speech is converted into second text data, user portrait collection is performed on the second text data, and user portrait data is obtained, wherein the user portrait data includes age, gender, location and specific needs of a client, so that potential needs of the client are mined according to the user portrait data.
With continued reference to fig. 4, tag keywords may be obtained through keyword retrieval or through contextual semantic association, the tag keywords may be clustered, such as purchasing preferences, interest preferences, potential needs, economic strength, etc., the customer tags may be analyzed, the customer information may be tagged, and the collection of user portrait data may be completed.
In some embodiments, after converting the feedback voice into the second text data, the emotional state of the second party during the call is analyzed based on the second text data, an emotion analysis index of the second party is obtained, and the success or failure of the sale is predicted based on the emotion analysis index.
With continued reference to fig. 4, by analyzing the emotional state of the second party during the call, an emotional analysis index such as optimism, anger, hesitation, etc. can be obtained, and the success of the sale can be predicted when the emotional analysis index of the second party is obtained as optimism.
In some embodiments, the obtaining a quality inspection report of the conversational speech according to the keyword matching result and the similarity calculation result in step S3300 further includes:
continuing to refer to fig. 4, selecting a corresponding assignment method according to the service requirement to perform weighted assignment calculation on the keyword matching result and the similarity calculation result, and performing quality inspection on the conversation voice according to the calculation result. For example, an entropy weight method, a standard deviation method, or a CRITIC method (criterion impact high intercritical correlation) may be selected to perform weighted assignment calculation on the keyword matching result and the similarity calculation result.
Entropy weight method: it is generally considered that if the entropy of the index is smaller, the larger the amount of information contained in the index is, the higher the proportion of the index in the overall evaluation should be. According to this principle, the weight calculation formula of the index given in this embodiment is as follows:
firstly according to the formula
Figure BDA0002376332310000091
The information entropy of the above two indexes (i.e., the keyword matching result and the similarity calculation result) is calculated.
Wherein, the parameter EjInformation entropy representing jth index, n is the number of evaluation objects, and parameter pijIs the specific gravity value, parameter dijTo normalize the data, if pijWhen the value is equal to 0, then
Figure BDA0002376332310000092
After the information entropies of the two indexes are calculated, the weight coefficient of each index is constructed by using the information entropies, and the specific calculation formula is as follows:
Figure BDA0002376332310000093
wherein the parameter wjThe weight coefficient of the jth index is shown, the parameter m is the number of indexes, and m is 2 in this embodiment.
Standard deviation method:
the idea of standard dispersion is quite similar to the entropy weight method, but it is based on standard deviation rather than information entropy. It is generally considered that the larger the standard deviation of an index is, the larger the variation of the index is, i.e. the more information contained therein, the larger the weight thereof should be. Based on this idea, the standard deviation sigma of the jth index is usedjCan adopt a formula
Figure BDA0002376332310000094
And calculating a weight coefficient.
CRITIC method:
CRITIC methodThe basic idea of (2) is to base on contrast strength and conflict when constructing weights. Wherein the contrast intensity is expressed in terms of standard deviation. Generally, the larger the standard deviation of the index, the larger the difference between the evaluation objects. The conflict is represented by the correlation coefficient between the indexes, and if the correlation between the indexes is strong, the conflict is weak. Based on the above thought, the present embodiment constructs the index c containing two kinds of informationjWherein c isjThe calculation formula of (2) is as follows:
Figure BDA0002376332310000101
as can be seen from the above indices, cjThe larger the information is, the more information is contained, and the larger the weight coefficient is. Therefore, the weighting factor of the j index can be expressed by the formula
Figure BDA0002376332310000102
And (4) calculating.
Fig. 5 shows a quality inspection report obtained by using the voice quality inspection method of the present embodiment, and in combination with fig. 5, the voice quality inspection method of the present embodiment can implement the following points:
1. marketing session technical quality inspection and evaluation: the quality inspection process marks key words such as required phrases and illegal phrases, scores calls according to quality inspection rules, supports manual sampling inspection, rechecks texts and recordings, and marks inconsistent conclusions. The embodiment outputs a quality inspection detailed table, a qualified (unqualified) condition, a spot inspection difference table and the like, and can also define grading detailed rules and corresponding addition and subtraction values by self, thereby quantifying the service quality and seeing the grading result more intuitively. And according to the scoring rules, the telephone traffic detection result, the content detection result, the hit recording details, the sub telephone traffic group and the seat risk details can be consulted.
2. And (3) mining the potential demands of the customers: the customer information is labeled by collecting the user portrait data, and the newly added label is synchronized to a customer management system, so that a basis is provided for later-stage accurate service.
3. And (3) predicting sales behaviors: predicting whether the sale is successful by collecting emotion analysis indexes;
4. optimizing a marketing strategy: and analyzing data of the quality-tested dialogue voice, carrying out telephone traffic statistics, hot spot division and abnormal analysis visual display, and providing a basis for decision making of a management layer.
