[0041] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0042] Figure 1 A flowchart of a text-to-speech playback method provided by an embodiment of the present invention is shown. Figure 2 The timing diagram of the text-to-speech playback method provided by the embodiment of the present invention is shown. The text-to-speech playback method is applied to a terminal, which can be a smart phone, a tablet computer or other smart terminal. Figure 1 and Figure 2 As shown, the method comprises the following steps:

[0043] Step 101: the H5 page responds to the play instruction received on the H5 page, and determines the text to be played on the H5 page based on the play instruction, the H5 page being the page currently displayed by the client;

[0044] Among them, the H5 page is the page currently displayed by the client or application APP, and the client or application APP can embed the H5 page through the WebView component. WebView is a native component that can load the H5 page in the client or APP and support interaction with the H5 page. When the text in the H5 page is selected by the user, for example, the user selects a piece of text in the H5 page and clicks the play button of the text-to-speech, the text-to-speech play instruction is triggered. After the play instruction is triggered, the JavaScript of the H5 page obtains the text selected by the user in the H5 page, and the text selected by the user will be converted into speech and played. Optionally, when the user selects the text on the H5 page, a menu that can be directly operated after the selected text pops up on the H5 page. The menu includes at least a text-to-speech play control, and the user can directly click the text-to-speech play control to trigger the play instruction.

[0045] Optionally, first, a click playback event listener can be added through the JavaScript of the H5 page to listen to the click event on the H5 page. When the user selects the text on the H5 page and clicks the corresponding text-to-speech playback element, the text-to-speech playback instruction is triggered, and then the content of the click event is obtained through the event object event, so that the text selected by the user can be accurately obtained.

[0046] Furthermore, in order to detect whether the selected text is empty, when the text-to-speech playback instruction is triggered on the H5 page, the JavaScript of the H5 page will determine whether the text selected by the user is empty, for example, calling the text check function to check the content selected by the user, and then removing the spaces that may exist in the content selected by the user. If the value after removing the spaces is an empty string, the text selected by the user is determined to be empty. Otherwise, the text selected by the user is determined to be not empty, and the string can be obtained as the text to be played by voice.

[0047] Step 102: the H5 page obtains a first playback parameter of the text to be played in voice, generates a first protocol according to the first playback parameter and the text to be played in voice, and sends the first protocol to the client;

[0048] Among them, the first playback parameter includes one or more, which may include a playback action type and a playback task identifier. The playback action type includes starting playback, pausing playback, continuing playback, stopping playback, and modifying speech speed, etc. It may also include selecting language and sound, adjusting volume, adjusting pitch, etc. The playback task identifier is used to identify the current playback task to distinguish it from other playback tasks. The first playback parameter is obtained according to the triggered instruction. For example, if the text-to-speech playback instruction is triggered for the first time, the corresponding playback action type is start playback, and a playback task identifier is assigned.

[0049] In an embodiment of the present invention, a first protocol is generated according to the first playback parameter and the text to be played by voice. The first protocol is a customized communication mechanism that can be recognized between the H5 page and the client. The first protocol is used to communicate between the H5 page and the client to realize the transmission of the first playback parameter and the text to be played by voice. It can be understood that other suitable protocols or communication methods similar to the first protocol can also be used to send the first playback parameter and the text to be played by voice on the H5 page to the client.

[0050] Alternatively, if Figure 2 As shown, the first protocol is the URL protocol. The JavaScript of the H5 page generates the URL protocol according to the first playback parameter and the text to be played by voice. The URL protocol is basically as follows:

[0051] Protocol name: / / TTSSpeaker / params={text, first playback parameter}.

[0052] For example, the first URL protocol is as follows: myapp: / / TTSSpeaker / params={"txt":"sample text","action":"0","id":"123"}&callback=ttsState;

[0053] Among them, myapp is the URL protocol name, TTSSpeaker is text-to-speech playback, txt is the text content to be played, in the first playback parameter, the parameter name and value are separated by ":", and action is the specified action type, for example, 0 means start playing, 1 means pause, 2 means continue, 3 means stop, and 4 means change the playback speed; id is used to identify the playback task; callback is the callback function provided by the H5 page, which is used to receive the client's playback status update.

[0054] In an embodiment of the present invention, when the H5 page does not embed a speech synthesis module and does not use the speech synthesis function provided by a third-party service, it does not have speech synthesis capabilities. The embodiment of the present invention sends the first playback parameter and the text to be voice played to the client in the form of a first protocol to utilize the client's local speech synthesis capabilities. The interaction between the two is simple and convenient, and does not require consuming too many resources.

[0055] Step 103: the client parses the first protocol to obtain the first playback parameter and the text to be voice played in the first protocol;

[0056] After receiving the first protocol, the client parses the first protocol locally to obtain the first playback parameter and the text to be played by voice. In order to ensure that the first playback parameter and the text to be played by voice in the first protocol are accurately obtained, in an optional embodiment, after the client parses the first protocol, it also includes: the client verifies whether the protocol name of the first protocol is a predetermined protocol name, and verifies whether the first playback parameter meets the preset parameter rules; if the name of the first protocol is a predetermined protocol name, and the first playback parameter meets the preset parameter rules, then executes the step of converting the text to be played by voice into voice data.

[0057] Among them, the client first verifies whether the protocol name is a predetermined protocol name, that is, the protocol name agreed upon by the H5 page and the client. If it is not the predetermined protocol name, no processing will be performed on the first protocol, and the first playback parameter and the text to be played by voice cannot be obtained; if it is the predetermined protocol name, it is further verified whether the first playback parameter meets the preset parameter rules, for example, whether the format of the parameter is the predetermined format, and whether the length of the parameter is the predetermined length, etc. If one of them does not meet the preset parameter rules, no processing will be performed on the first protocol, and the first playback parameter and the text to be played by voice cannot be obtained. On the contrary, if the first playback parameter meets the preset parameter rules, accurate first playback parameters and text are obtained.

[0058] Step 104: The client converts the text to be played as voice into voice data, and plays the voice data according to the first playing parameters.

[0059] In an embodiment of the present invention, the text to be played by voice is converted into voice data locally on the client to play the voice data. In order to utilize the local text-to-speech capability of the client and to play the voice data conveniently and quickly, in an optional embodiment, the client converts the text to be played by voice into voice data, and plays the voice data according to the first playback parameter, including: the client calls the text-to-speech engine built into the client, and uses the text-to-speech engine to convert the text to be played by voice into voice data; calls the player built into the client, and plays the voice data in the player according to the first playback parameter.

[0060] Among them, the client first calls the built-in text-to-speech engine to convert text into voice data, and then calls its built-in player to play the voice data, realizing the client's local text-to-speech and local voice playback. This method is convenient and efficient. In other optional embodiments, since the H5 page has a voice playback function, the client can also call the built-in text-to-speech engine to convert text into voice data, and then send the voice data to the H5 page for playback, thereby improving the flexibility of voice playback.

[0061] In an optional embodiment, in order to achieve a better audio-visual effect and enhance the user's audio-visual experience, a first playback parameter of the text to be played by voice is obtained on the H5 page, and a first protocol is generated according to the first playback parameter and the text to be played by voice, including: obtaining the first playback parameter and a callback function of the text to be played by voice, and generating the first protocol according to the first playback parameter, the callback function and the text to be played by voice;

[0062] The client converts the text to be played into voice data, and after playing the voice data according to the first playback parameter, it also includes: the client monitors the current playback status, and sends the monitored playback status information to the H5 page based on the callback function, so that the H5 page can update the currently displayed playback status.

[0063] In the embodiment of the present invention, if the first protocol carries a callback function, the client can feed back the playback status to the H5 page in real time through the callback function. Optionally, the client can call the monitoring function to monitor the playback of the voice data in real time. Once the voice data starts to be played, the playback status information monitored in real time by the client is the start of playback, and the start of playback information is sent to the H5 page through the callback function, and the H5 page updates the currently displayed playback status to start of playback.

[0064] In an optional embodiment, after the play instruction is triggered, the H5 page displays the play control corresponding to the text to be played by voice, for example, a triangle is displayed in the play control, and the triangle represents the state of not playing, pausing or stopping the play. After the H5 page receives the callback function sent by the client, it updates the currently displayed play status according to the play status information in the callback function, including: the H5 page updates the play control, for example, the play control updates the triangle to a double vertical bar, and the double vertical bar represents playing. The client uses the callback function to feedback the play status, and the H5 page promptly updates the currently displayed play control to represent different play states, so that the client starts playing the H5 page and promptly updates the play control, achieving a natural and smooth effect in audio and video, and improving the user experience.

[0065] In an optional embodiment, the client converts the text to be played voice data, and after playing the voice data according to the first playback parameter, it also includes: the H5 page responds to the playback status change instruction received on the H5 page, determines the second playback parameter based on the playback status change instruction, generates a second protocol according to the second playback parameter, and sends the second protocol to the client; the client parses the second protocol, obtains the second playback parameter in the second protocol, and changes the current playback status according to the second playback parameter.

[0066] In an embodiment of the present invention, the user actively changes the playback state and clicks a corresponding playback control on the H5 page to trigger a playback state change instruction, for example, changing from the playback state to the paused playback state, or modifying the playback speech speed, etc. The H5 page determines the changed second playback parameter and generates a second protocol. The method for generating the second protocol is basically the same as the method for generating the first protocol. The second protocol is used to communicate between the H5 page and the client to realize the transmission of the changed second playback parameter.

[0067] Optionally, the second protocol is also a URL protocol. The JavaScript of the H5 page generates a URL protocol according to the changed second playback parameter. The URL protocol is basically as follows:

[0068] Protocol name: / / TTSSpeaker / params={second playback parameter}.

[0069] For example, the second URL protocol is as follows: myapp: / / TTSSpeaker / params={"action":"3","id":"123"};

[0070] Wherein, action is a specified action type, for example, 3 represents stop; id=123 is used to identify the play task.

[0071] After receiving the second protocol, the client parses the second protocol to obtain the second playback parameters, and promptly changes the current playback state, for example, from the playback state to the paused playback state, or changes the playback speed, etc., so that the front-end triggers the change and the client changes in time. In terms of audio-visual effects, the playback is smooth and natural without any delay.

[0072] Optionally, both the first playback parameter and the second playback parameter include a playback task identifier. To improve reliability, after the client parses the second protocol, a verification step is also included: the client verifies whether the protocol name of the second protocol is a predetermined protocol name, verifies whether the second playback parameter complies with preset parameter rules, and verifies whether the playback task identifier in the second playback parameter is the same as the playback task identifier in the first playback parameter; if the name of the second protocol is a predetermined protocol name, and the second playback parameter complies with preset parameter rules, and the playback task identifier in the second playback parameter is the same as the playback task identifier in the first playback parameter, then a step of changing the current playback status according to the second playback parameter is executed.

[0073] The process of verifying the protocol name and the second playback parameter in the embodiment of the present invention is basically the same as the verification process in the above embodiment, and will not be repeated here. As for the verification of the playback task identifier, it is to identify whether it is the same playback task. If it is a different playback task, the client will not execute the change of the playback state. On the contrary, if it is the same playback task, the client will execute the change of the playback state. It can be understood that the above-mentioned protocol name verification, second playback parameter verification and playback task identifier verification are not in a particular order.

[0074] In an embodiment of the present invention, the H5 page responds to the play instruction received on the H5 page, determines the text to be voice played on the H5 page based on the play instruction, and the H5 page is the page currently displayed by the client; the H5 page obtains the first play parameter of the text to be voice played, generates a first protocol according to the first play parameter and the text to be voice played, and sends the first protocol to the client; the client parses the first protocol, obtains the first play parameter in the first protocol and the text to be voice played; the client converts the text to be voice played into voice data, and plays the voice data according to the first play parameter. The embodiment of the present invention establishes a mutually recognizable communication mechanism between the H5 page and the client, transmits the text of the H5 page to the client through the first protocol, and utilizes the local speech synthesis capability of the client to realize local offline speech synthesis, converts the text into speech and plays it. The mechanism is independent of the network request and is directly executed on the local client, eliminating the dependence on the network request, reducing the load and resource consumption of the background server, thereby expanding the capabilities of the H5 page and enabling it to have the text-to-speech playback function; by directly calling the first protocol and using the speech synthesis capability of the client, compared with the prior art of integrating additional modules in the H5 page or relying on external third-party services, the complexity of development can be greatly reduced, the steps of function integration are simplified, and the entire implementation process is simple and efficient.
