Example one
Fig. 1 is a flowchart illustrating steps of an audio positioning method according to an embodiment of the present invention. The method comprises the following steps:
In this embodiment, a user inputs first audio data including search content to a mobile terminal, and the mobile terminal receives the first audio data submitted by the user. The first audio data may contain a word or may contain a plurality of words. For example, the user inputs first audio data containing the search content "the second content is Y", and the mobile terminal receives the first audio data. The first audio data is not limited in detail in the embodiment of the present invention, and may be set according to actual situations.
In this embodiment, after receiving the first audio data, the first key information is extracted from the first audio data. Specifically, the first audio data may be converted into text content and displayed on a screen of the mobile terminal, and first key information selected by a user from the plurality of text contents may be received. For example, the first audio data is converted into a text content of "Y is the second content", and "Y" selected by the user is received as the first key information. Or converting the first audio data into text content, splitting the text content into a plurality of phrases, and using the split phrases as the first key information. For example, the first audio data is converted into text content "the second content is Y", two phrases "the second" and "Y" are split from the text content, and the "second" and "Y" are used as the first key information. The embodiment of the invention does not limit in detail how to extract the first key information, and can be set according to actual conditions.
In this embodiment, the second audio data is to-be-identified audio data, and after the first key information is extracted from the first audio data, the sub audio data matched with the first key information is searched from the second audio data. Specifically, the second audio data may be converted into text content, a phrase matching the first key information is found from the text content, and the audio data where the matching phrase is located is used as the found sub-audio data. For example, the converting the second audio data into text content includes: today's conferences include three pieces of content X, Y, Z; the first content is X … …; the second content is Y … …; the third is Z … …. And finding the phrase "second" and "Y" matched with the first key information from the converted text content, wherein the "second content is Y … …" is the found sub-audio data. The embodiment of the invention does not limit the division of the molecular audio data in detail, and can be set according to the actual situation.
And 104, adding a characteristic mark to the sub-audio data.
In this embodiment, a feature mark is added to the searched sub audio data. For example, if the searched sub audio data is between 0:31 '45 "-0: 57' 11" of the second audio data, the sub audio data between 0:31 '45 "-0: 57' 11" may be marked with a special color to distinguish the searched sub audio data from other audio data; a label may also be displayed at 0: 31' 45 ". The embodiment of the invention does not limit in detail how the feature mark is added, and can be set according to actual conditions.
In summary, in the embodiment of the present invention, the mobile terminal extracts the first key information from the first audio data, searches for the sub-audio data in the second audio data that matches the first key information, and adds the feature tag to the searched sub-audio data, so that the user can quickly find the required content from the second audio data according to the feature tag, thereby improving the efficiency of repeatedly listening to the recording, and improving the user experience when the user repeatedly listens to the recording.
Example two
Fig. 2 is a flowchart illustrating steps of an audio positioning method according to an embodiment of the present invention. The method comprises the following steps:
In this embodiment, the second audio data is subjected to speech recognition, and the audio content of the second audio data is recognized. For example, the second audio data is subjected to speech recognition, and the recognized audio content includes: today's conferences include three pieces of content X, Y, Z; the first content is X … …; the second content is Y … …; the third is Z … …. The embodiment of the invention does not limit the speech recognition in detail, and can be set according to the actual situation.
In this embodiment, the second audio data is divided according to the audio content. For example, the second audio data is divided into four sub-audio data according to the audio contents, the first sub-audio data including "the conference today includes three contents X, Y, Z"; the second sub audio data includes "the first content is X … …", and the third sub audio data includes "the second content is Y … …"; the fourth sub audio data includes "the third content is Z … …".
In this embodiment, searching for the sub audio data matched with the first key information from the plurality of sub audio data may specifically include the following steps:
and the first substep is to extract second key information for each sub audio data.
In this embodiment, after the second audio data is divided into a plurality of sub audio data, the second key information is extracted from each sub audio data. For example, second key information is extracted for the first sub audio data, the second key information being "three", "X", "Y", "Z"; extracting second key information from the second sub-audio data, wherein the second key information is 'first' and 'X'; extracting second key information from the third sub-audio data, wherein the second key information is 'second', 'Y'; and extracting second key information from the fourth sub audio data, wherein the second key information is 'third' and 'Z'.
And a second substep of performing word sense matching on the first key information and the second key information and determining the matching degree of the content of the first key information and the content of each piece of sub-audio data.
In this embodiment, word sense matching is performed on the first key information and the second key information. For example, the first key information "second" and "Y" are word sense-matched with the second key information "third", "X", "Y" and "Z" of the first sub-audio data, word sense-matched with the second key information "first" and "X" of the second sub-audio data, word sense-matched with the second key information "second" and "Y" of the third sub-audio data, and word sense-matched with the second key information "third" and "Z" of the fourth sub-audio data. Optionally, the word sense matching includes at least one of same word matching, similar word matching, and multilingual matching. Word banks can be established for matching by matching of near-meaning words, similar words and multiple languages. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
And after word sense matching, determining the matching degree of the content of the first key information and the content of each sub audio data. For example, the second key information "Y" in the first sub-audio data matches "Y" in the first key information, which accounts for 1/2 of the two first key information, and the matching degree is determined to be 50%; the second key information in the second sub audio data is not matched with the first key information, and the matching degree is determined to be 0; the second key information "second" and "Y" in the third sub-audio data are matched with the second key information "second" and "Y" in the first key information, the matching degree is determined to be 100%, the second key information in the fourth sub-audio data is not matched with the first key information, and the matching degree is determined to be 0. For example, the second key information extracted from the third sub-audio data includes 10 pieces of "second", 8 pieces of "Y", and 1 piece of "a", and after performing word sense matching with the first key information, the number of matches is 9, and the matching degree is determined to be 90%. How to determine the matching degree is not limited in detail in this embodiment, and may be set according to actual situations.
And a third substep of searching the sub-audio data with the matching degree meeting the preset condition.
In this embodiment, after the matching degree between the first key information and each piece of sub-audio data is determined, the sub-audio data whose matching degree meets the preset condition is searched. For example, if the preset condition is that the matching degree is greater than 80%, the third sub-audio data is found; if the preset condition is that the matching degree is greater than or equal to 50%, the first sub audio data and the third sub audio data are searched. The preset conditions are not limited in detail in the embodiment of the invention, and can be set according to actual conditions.
In step 206, corresponding feature labels are added to the plurality of searched sub-audio data.
In this embodiment, the found sub audio data is added with the feature marks respectively, for example, the first sub audio data and the third sub audio data are found, a red mark may be added to the first sub audio data, and a yellow mark may be added to the third sub audio data; it is also possible to add a mark containing "Y" to the first sub audio data and a mark containing "Y" to the third sub audio data. The embodiment of the invention does not limit the feature marks in detail, and can be set according to actual conditions.
And step 207, receiving a click operation instruction for the feature tag.
In this embodiment, when the user finds the content to be listened to again according to the feature tag, the user clicks the feature tag, and the mobile terminal receives an operation instruction for clicking the feature tag. For example, the mobile terminal receives an operation instruction of clicking a yellow mark.
And step 208, playing the sub-audio data corresponding to the feature tag.
In this embodiment, after receiving an operation instruction for clicking the feature tag, the sub-audio data corresponding to the feature tag is played. For example, after receiving an operation instruction of clicking the yellow mark, the third sub-audio data "the second content is Y … …" corresponding to the yellow mark is played. Therefore, the user can quickly find the required content from the second audio data according to the feature marks, and the efficiency of listening to the recording again is improved.
In summary, in the embodiment of the present invention, the mobile terminal extracts the first key information from the first audio data, matches the second audio data with the first key information, and adds the feature tag to the sub-audio data in the second audio data that matches the first key information, so that the user can quickly find the required content from the second audio data according to the feature tag, thereby improving the efficiency of repeatedly listening to the recording and improving the user experience when the user repeatedly listens to the recording.
