Description
技术领域technical field
本发明涉及语音识别技术领域,更具体地,涉及一种用于语音识别文本的方法、设备、客户端装置及电子设备。The present invention relates to the technical field of speech recognition, and more specifically, to a method, device, client device and electronic device for speech recognition text.
背景技术Background technique
随着智能终端的硬件不断升级和系统不断完善,它提供用户交互的手段和方式也越来越多。此外,随着移动互联网使用量的爆发式增长,用户使用手机应用(APP)来解决日常生活需求的场景也越来越多。As the hardware of the smart terminal continues to upgrade and the system continues to improve, it provides more and more means and methods for user interaction. In addition, with the explosive growth of mobile Internet usage, there are more and more scenarios where users use mobile applications (APP) to solve their daily needs.
语音识别技术在手机应用上的应用也越来越广泛。例如,许多搜索引擎、移动浏览器、电商类的APP等都能够支持将用户录入的语音转换为文本以进行搜索的功能。Speech recognition technology is also more and more widely used in mobile phone applications. For example, many search engines, mobile browsers, e-commerce APPs, etc. can support the function of converting the voice entered by the user into text for searching.
在很多语言中,存在许多发音相同或近似而意思不同的词。尤其在中文中,同音词/近似音词的比例比较高。为了较为准确地从同音词/近似音词集合中识别出用户期望的词,在现有技术中,通常采用的方案是,基于用户完整语段的语义,选择一个最合适的词作为识别出的文本显示给用户。然而,在许多情况下,现有技术的方案不是有效的。例如,当用户仅录入单个词或者录入的语音出现断词时,现有技术的方案无法从同音词/近似音词集合中识别出符合用户期望的词,语音识别的准确率较低。In many languages, there are many words with the same or similar sound but different meanings. Especially in Chinese, the proportion of homonyms/approximate words is relatively high. In order to more accurately identify the word expected by the user from the set of homophones/approximate words, in the prior art, the usual solution is to select the most appropriate word as the recognized text based on the semantics of the user's complete segment displayed to the user. However, in many cases, prior art solutions are not effective. For example, when the user only enters a single word or the entered speech is segmented, the solutions in the prior art cannot identify words that meet the user's expectations from the homonym/approximate word set, and the accuracy of speech recognition is low.
因此,发明人认为,有必要对上述现有技术中存在的问题进行改进。Therefore, the inventor believes that it is necessary to improve the problems existing in the above-mentioned prior art.

下面,参照附图描述根据本公开的各个实施例和例子。Hereinafter, various embodiments and examples according to the present disclosure are described with reference to the accompanying drawings.
<方法><method>
图1示出了根据本公开的一个实施例的方法的示意性流程图。Fig. 1 shows a schematic flowchart of a method according to an embodiment of the present disclosure.
如图1所示,在步骤1100,接收来自用户的语音输入。As shown in FIG. 1, at step 1100, voice input from a user is received.
例如,具有语音识别功能的客户端装置(客户端应用)接收来自用户的交互操作,以进入到语音识别的交互界面,并在该交互界面接收用户的语音输入。For example, a client device (client application) having a speech recognition function receives an interactive operation from a user to enter an interactive interface for speech recognition, and receives the user's voice input on the interactive interface.
步骤1200,对所述语音输入进行识别,以提供至少两个备选关联词。Step 1200, recognize the speech input to provide at least two candidate associated words.
例如,备选关联词是指具有相同语音指纹的词,并可以被预先存储在关联词词库中。语音指纹是词的发音特征标识。例如,对于中文(普通话语系),词的拼音可以作为语音指纹。例如,一个语音指纹的例子是“jianpu”。在普通话语系中,与该语音指纹关联的词可以包括以下词:简谱、简朴、俭朴,等等。For example, alternative associated words refer to words with the same phonetic fingerprint, and may be pre-stored in the associated word lexicon. Speech fingerprint is the pronunciation feature identification of words. For example, for Chinese (a Mandarin family), the pinyin of a word can be used as a phonetic fingerprint. For example, an example of a voice fingerprint is "jianpu". In the Mandarin family, words associated with the phonetic fingerprint may include the following words: numbered notation, simple, frugal, and so on.
在一个例子中,可以利用如图2所示的方式实现所述步骤S1200。In an example, the step S1200 may be implemented in a manner as shown in FIG. 2 .
如图2所示,在步骤1201,对所述语音输入进行识别,以得到该语音输入的语音指纹。As shown in FIG. 2, in step 1201, the voice input is recognized to obtain a voice fingerprint of the voice input.
所述语音指纹是与所述语音输入相关联的发音特征标识。例如,与语音输入相关联的发音特征标识是语音输入的拼音,它可以作为识别到的语音指纹。The voice fingerprint is an identification of pronunciation features associated with the voice input. For example, the pronunciation feature identifier associated with the speech input is the pinyin of the speech input, which can be used as the recognized speech fingerprint.
步骤1202,查询关联词词库以得到与所述语音指纹相关联的至少两个备选关联词。Step 1202, query the associated word thesaurus to obtain at least two candidate associated words associated with the voice fingerprint.
例如,在关联词词库中,可以将与语音指纹对应的多个关联词以列表的形式进行存储。在关联词词库的初始状态下,词的顺序可以是根据词在日常社会交流中的使用频率由高到低排序,其中,使用频率高的词位置靠前。可以将关联词在列表中的顺序作为显示时的位置顺序。例如,如果备选关联词在列表中的位置是第一位,则在向用户显示时,与该备选关联词对应的数字为“1”。For example, in the associated word thesaurus, multiple associated words corresponding to voice fingerprints may be stored in the form of a list. In the initial state of the associated word thesaurus, the order of words can be sorted from high to low according to the frequency of use of words in daily social communication, wherein the words with high frequency of use are placed first. The order of the associated words in the list can be used as the order of position when displayed. For example, if the position of the candidate associated word is the first in the list, when displayed to the user, the number corresponding to the candidate associated word is "1".
当得到语音输入的语音指纹后,若关联词词库中存在与该语音指纹对应的至少两个关联词,则将所述至少两个关联词作为备选关联词。本领域技术人员应当理解,如果关联词词库中仅存在一个与语音指纹相关联的备选关联词,则可以直接将该备选关联词作为语音识别的文本。After the voice fingerprint of the voice input is obtained, if there are at least two associated words corresponding to the voice fingerprint in the associated word lexicon, the at least two associated words are used as candidate associated words. Those skilled in the art should understand that if there is only one candidate associated word associated with the voice fingerprint in the associated word lexicon, the candidate associated word can be directly used as the speech recognition text.
步骤1203,向用户显示所述至少两个备选关联词。Step 1203, displaying the at least two candidate associated words to the user.
这里,可以将所显示的备选关联词的数量设置得小于等于10。如果关联词词库中的备选关联词的数量大于10,则在显示时,仅选取前10个词作为备选关联词。Here, the number of displayed alternative associated words can be set to be less than or equal to 10. If the number of alternative associated words in the associated word thesaurus is greater than 10, only the first 10 words are selected as alternative associated words when displayed.
在显示至少两个备选关联词时,每个备选关联词与数字1-10中的一个数字对应,以便于用户通过输入指令语音选取目标关联词。When at least two candidate associated words are displayed, each candidate associated word corresponds to a number in numbers 1-10, so that the user selects the target associated word by inputting an instruction voice.
这种方式的有利之处在于,通常,在各种语言中,尤其在中文中,数字1-10都是单音节词和/或容易识别。因此,限制备选关联词的数量可以提高用户选择备选关联词时的识别正确率。The advantage of this approach is that, generally, in various languages, especially in Chinese, numbers 1-10 are all monosyllabic and/or easy to recognize. Therefore, limiting the number of candidate associated words can improve the recognition accuracy when the user selects the candidate associated words.
此外,当备选关联词的数量大于10时,可以设置单独的特定词语,例如“下一页”,并通过该特定词语实现备选关联词的更换。用户可以在更换的备选关联词中选择期望的词。In addition, when the number of alternative associated words is greater than 10, a separate specific word, such as "next page", can be set, and the replacement of the alternative associated words can be realized through this specific word. The user can select a desired word among the replaced candidate associated words.
向用户显示至少两个备选关联词之后,进入步骤1300、接收来自用户的指令语音。After at least two candidate associated words are displayed to the user, enter step 1300, and receive an instruction voice from the user.
这里,数字1-10是单音节的,且数字的识别率非常高,可以保证指令语音识别的高精准度。在本例中,定义指令语音是单音节语音。此外,语音指令是有限指令集合内的指令,例如,来自用户的指令语音是数字1-10中的一个。Here, the numbers 1-10 are monosyllabic, and the recognition rate of the numbers is very high, which can ensure the high accuracy of command voice recognition. In this example, the command voice is defined as a monosyllabic voice. In addition, the voice command is an command within a limited set of commands, for example, the command voice from the user is one of numbers 1-10.
例如,根据来自用户的语音输入识别到的语音指纹是“jingzhi”,向用户显示的与“jingzhi”相关联的备选关联词分别为“1.静止”“2.精致”、“3.净值”、“4.精制”。若用户选择“精致”作为目标关联词,则录入“2”作为语音指令。For example, the voice fingerprint recognized according to the voice input from the user is "jingzhi", and the alternative associated words associated with "jingzhi" displayed to the user are "1. Stillness", "2. Delicacy", and "3. Net worth" , "4. Refined". If the user selects "exquisite" as the target associated word, then enter "2" as the voice command.
在一个例子中,接收来自用户的指令语音还可以包括:接收用户的指示语音,其中,所述指示语音包括多个音节并且包括单音节语音的指令语音。In an example, receiving an instruction voice from the user may further include: receiving an instruction voice from the user, wherein the instruction voice includes multiple syllables and includes a single-syllable voice instruction voice.
例如,用户选择所显示的第二个词作为目标关联词,可以录入指示语音“第2个词”,该指示语音包括多个音节,且包括了单音节语音的指令语音“2”。For example, if the user selects the displayed second word as the target associated word, the user can enter the instruction voice "the second word", which includes multiple syllables and includes the monosyllable instruction voice "2".
这种录入指示语音的方式在实际应用中可能较为符合用户的习惯,这样既能增强用户的使用体验,也可以保证指令识别的准确和简便。This method of inputting instruction voice may be more in line with the user's habits in practical applications, which can not only enhance the user's experience, but also ensure the accuracy and convenience of instruction recognition.
在另一个例子中,若在预定时间内没有接收到来自用户的指令语音时,还可以提示用户输入指令语音。In another example, if no instruction voice is received from the user within a predetermined time, the user may be prompted to input the instruction voice.
具体地,可以在显示至少两个备选关联词的同时,显示预定时间的倒计时,以提示用户在倒计时结束前录入指令语音。可选地,可以在到达预定时间时,显示提示信息以提示用户输入指令语音。Specifically, a countdown of a predetermined time may be displayed while at least two candidate associated words are displayed, so as to prompt the user to input an instruction voice before the countdown ends. Optionally, when the predetermined time is reached, prompt information may be displayed to prompt the user to input an instruction voice.
在步骤1400,对所述指令语音进行识别,以得到语音指令,其中,所述语音指令用于确定所述至少两个备选关联词中的目标关联词。In step 1400, the instruction voice is recognized to obtain a voice instruction, wherein the voice instruction is used to determine a target associated word among the at least two candidate associated words.
在一个例子中,用户录入的指令语音是单音节语音,对指令语音进行识别即可直接得到语音指令。例如,对于备选关联词“1.静止”“2.精致”、“3.净值”、“4.精制”,假设用户录入的指令语音为“1”,则对指令语音进行识别得到的语音指令即为“1”。In one example, the command voice entered by the user is a monosyllable voice, and the voice command can be obtained directly by recognizing the command voice. For example, for the alternative associated words "1. Stillness", "2. Refined", "3. Net worth", and "4. Refined", assuming that the command voice entered by the user is "1", the voice command obtained by recognizing the command voice That is "1".
在另一个例子中,用户录入的是指示语音,相应的,对指令语音进行识别还可以包括:确定指示语音中的指令语音;基于单音节的方式对指令语音进行识别,以得到语音指令。In another example, what the user enters is an instruction voice, and correspondingly, recognizing the instruction voice may also include: determining the instruction voice in the instruction voice; and recognizing the instruction voice based on a monosyllable manner to obtain the voice instruction.
例如,对于备选关联词“1.静止”“2.精致”、“3.净值”、“4.精制”,用户录入的指示语音是“第1个词”,确定出指示语音中的指令语音“1”,基于单音节的方式对指令语音进行识别,得到的语音指令为“1”。For example, for the alternative associated words "1. static", "2. exquisite", "3. net value", "4. refined", the instruction voice entered by the user is "the first word", and the instruction voice in the instruction voice is determined "1", the instruction voice is recognized based on the monosyllable method, and the obtained voice instruction is "1".
在实际应用中,在确定目标关联词后,还可以对所确定的目标关联词进行变色显示,使其从颜色上区别于其他备选关联词,以标识该词为选中词。In practical applications, after the target associated word is determined, the determined target associated word can also be displayed in color, so that it can be distinguished from other alternative associated words in color, so as to identify the word as the selected word.
可以理解的是,若在本步骤中未识别到语音指令,则提示用户本次识别无效,用户可选择重新录入语音,或者完成本次语音识别。It can be understood that if no voice command is recognized in this step, the user is prompted that the current recognition is invalid, and the user can choose to re-enter the voice or complete the current voice recognition.
步骤1500,基于所述语音指令确定目标关联词,作为所识别的文本。Step 1500, determine target related words as the recognized text based on the voice instruction.
将与语音指令对应的备选关联词确定为目标关联词。该目标关联词是基于用户的语音输入所识别的文本。例如,对于备选关联词“1.静止”“2.精致”、“3.净值”、“4.精制”,若语音指令为“1”,对应的“静止”是基于用户的语音输入所识别的文本。The candidate associated word corresponding to the voice instruction is determined as the target associated word. The target link is text recognized based on the user's speech input. For example, for the alternative associated words "1. still", "2. refined", "3. net worth", "4. refined", if the voice command is "1", the corresponding "stationary" is recognized based on the user's voice input of the text.
在一个例子中,在基于语音指令确定目标关联词之后,还可以基于所确定的目标关联词,调整与所述语音指纹相关联的至少两个备选关联词的位置顺序。例如,可以将目标关联词放在与语音指纹相关联的至少两个备选关联词的第一位,利用用户的选择结果来调整备选关联词的顺序,以在下次识别时提高推荐的准确性,提升用户体验。In an example, after the target associated word is determined based on the voice instruction, the positions of at least two candidate associated words associated with the voice fingerprint may be adjusted based on the determined target associated word. For example, the target associated word can be placed in the first position of at least two alternative associated words associated with the voice fingerprint, and the order of the alternative associated words can be adjusted by using the user's selection result, so as to improve the accuracy of recommendation in the next recognition, and improve user experience.
在这个实施例中,可以基于用户主动输入的指令语音来修正从同音词/近似音词集合中识别出符合用户期望的文本,提升语音识别文本的准确性。In this embodiment, based on the command voice actively input by the user, the text recognized from the homonym/approximate phonetic word set that meets the user's expectations can be corrected to improve the accuracy of the speech recognition text.

<例子><example>
图5a~图5b示出了根据本公开的实施例的一个例子的显示界面的示意图。5a to 5b show schematic diagrams of a display interface according to an example of an embodiment of the present disclosure.
在本例中,以浏览器的语音识别交互界面为例进行描述。In this example, the speech recognition interactive interface of the browser is taken as an example for description.
用户通过与浏览器的显示界面的交互操作,进入语音识别交互界面。如图5a所示,在语音识别交互界面可以显示例如“倾听中”这样的提示字样提示用户当前可以录入语音。The user enters the voice recognition interaction interface through an interactive operation with the display interface of the browser. As shown in FIG. 5 a , a prompt such as "Listening" may be displayed on the voice recognition interaction interface to prompt the user that voice can be input currently.
在进入语音识别交互界面后,接收来自用户的语音输入,识别得到该语音输入的语音指纹。接着,查询关联词词库中是否存在与语音指纹相关联的备选关联词。After entering the voice recognition interaction interface, the voice input from the user is received, and the voice fingerprint of the voice input is recognized. Next, query whether there are candidate associated words associated with the voice fingerprint in the associated word lexicon.
如果查询到关联词词库中存在的与语音指纹相关联的备选关联词数量为一个,则将该备选关联词确定为所识别的文本并将它显示在语音识别交互界面上。如果查询到关联词词库中存在的与语音指纹相关联的备选关联词的数量为至少两个,在语音识别交互界面按照顺序显示所述至少两个备选关联词,且每个备选关联词与数字1-10中的一个数字对应。If it is found that there is one candidate associated word associated with the voice fingerprint in the associated word thesaurus, the candidate associated word is determined as the recognized text and displayed on the speech recognition interface. If it is found that the number of alternative associated words associated with voice fingerprints that exists in the associated word lexicon is at least two, the at least two alternative associated words are displayed in order on the voice recognition interface, and each alternative associated word is associated with a number Corresponds to a number from 1-10.
例如,识别到的语音指纹是“jianpu”,查询到关联词词库中与“jianpu”相关联的备选关联词有三个:“简谱”“简朴”“俭朴”。按照词的顺序在语音识别交互界面显示这三个备选关联词,且每个备选关联词与1-10中的一个数字对应。如图5b所示,在语音识别交互界面显示为:“1.简谱”“2.简朴”“3.俭朴”。For example, the recognized voice fingerprint is "jianpu", and there are three candidate associated words associated with "jianpu" in the associated word lexicon: "simplified musical notation", "simple" and "simple". These three candidate associated words are displayed on the voice recognition interface in the order of words, and each candidate associated word corresponds to a number in 1-10. As shown in Figure 5b, the voice recognition interface displays: "1. Numbered musical notation", "2. Simple" and "3. Simple".
在语音识别交互界面显示至少三个备选关联词时,还可以同时显示倒计时,以提示用户录入指令语音。该指令语音可以是用户录入的单音节语音,也可以是用户录入的指示语音,该指示语音包括多个音节且包括单音节语音的指令语音。When at least three alternative associated words are displayed on the voice recognition interactive interface, a countdown may also be displayed at the same time to prompt the user to input an instruction voice. The command voice may be a monosyllabic voice entered by the user, or an instruction voice entered by the user, the instruction voice including multiple syllables and including a single-syllable voice.
在倒计时时间内接收用户输入的指令语音。如果用户在倒计时时段内录入了正确且有效的单音节指令,即识别出的语音指令是数字,且该数字不大于当前显示的备选关联词的数量,则将与语音指令对应的备选关联词确定为目标关联词,作为所识别的文本。可选地,可以将目标关联词进行变色显示,使目标关联词的显示颜色区别于其他备选关联词的显示颜色,以标识其为选中词。Receive the command voice input by the user within the countdown time. If the user enters a correct and valid monosyllabic instruction within the countdown period, that is, the recognized voice instruction is a number, and the number is not greater than the number of currently displayed alternative associated words, the alternative associated words corresponding to the voice instruction will be determined is the target linker, as the recognized text. Optionally, the target associated word may be displayed in a color-changing manner, so that the display color of the target associated word is different from that of other candidate associated words, so as to identify it as a selected word.
如果用户在倒计时时段内没有录入指令语音,或者用户录入了非数字语音指令,则提示用户本次语音识别无效。用户可选择重新录入语音或完成本次语音识别。If the user does not enter an instruction voice within the countdown period, or if the user enters a non-digit voice instruction, the user will be prompted that the speech recognition is invalid this time. The user can choose to re-enter the voice or complete this voice recognition.
若用户选择重新录入语音,则语音识别交互界面可以显示例如“倾听中”的字样提示用户可以录入语音。若用户选择完成本次语音识别,则退出语音识别交互界面。If the user chooses to re-enter the voice, the voice recognition interface may display, for example, "Listening" to prompt the user to input the voice. If the user chooses to complete the speech recognition, the speech recognition interaction interface will be exited.
在这个例子中,可以基于用户主动输入的指令语音来修正从同音词/近似音词集合中识别出符合用户期望的文本,提升语音识别文本的准确性。In this example, based on the instruction voice actively input by the user, it is possible to modify the text that meets the user's expectations from the set of homonyms/approximate words, so as to improve the accuracy of the speech recognition text.
