3 Apr 202513 minutes to read

The Essential JS 2 for JavaScript (global script) is an ES5 formatted pure JavaScript framework which can be directly used in latest web browsers.

Dependencies

The list of dependencies required to use the SpeechToText control in your application is given as follows:

|-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-popups

Control Initialization

The JavaScript (ES5) SpeechToText control can be initialized by using either of the following ways.

  • Using local script and style references in a HTML page.
  • Using CDN link for script and style reference.

Using local script and style references in a HTML page

Step 1: Create an app folder quickstart for getting started.

Step 2: You can get the global scripts and styles from the Essential Studio JavaScript (Essential JS 2) build installed location.

Syntax:

Dependency Script: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{DEPENDENCY_PACKAGE_NAME}\dist\global\{DEPENDENCY_PACKAGE_NAME}.min.js

Control Script: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{PACKAGE_NAME}\dist\global\{PACKAGE_NAME}.min.js

Dependency Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{DEPENDENCY_PACKAGE_NAME}\styles\material.css

Control Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\{PACKAGE_NAME}\styles\material.css

Example:

Dependency Script: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-base\dist\global\ej2-base.min.js

Control Script: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-inputs\dist\global\ej2-inputs.min.js

Dependency Styles: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-base\styles\material.css

Control Styles: C:\Program Files (x86)\Syncfusion\Essential Studio\JavaScript - EJ2\16.3.0.17\Web (Essential JS 2)\JavaScript\ej2-inputs\styles\material.css

The below located script and style file contains all Syncfusion JavaScript (ES5) UI control resources in a single file.

Scripts: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\dist\ej2.min.js

Styles: **(installed location)**\Syncfusion\Essential Studio\JavaScript - EJ2\{RELEASE_VERSION}\Web (Essential JS 2)\JavaScript\ej2\material.css

The Custom Resource Generator (CRG) is an online web tool, which can be used to generate the custom script and styles for a set of specific controls. This web tool is useful to combine the required control scripts and styles in a single file.

Step 3: Create a folder ~/quickstart/resources and copy/paste the global scripts and styles from the above installed location to ~/quickstart/resources/package corresponding package location.

Step 4: Create a HTML page (index.html) in ~/quickstart/index.html location and add the Essentials JS 2 script and style references.

          <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
          <link href="resources/buttons/material.css" rel="stylesheet" type="text/css"/>

          <!-- JavaScript (ES5) SpeechToText's control style -->
          <link href="resources/inputs/material.css" rel="stylesheet" type="text/css"/>

          <!-- JavaScript (ES5) SpeechToText's dependency global script -->
          <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
          <script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
          <script src="resources/popups/ej2-popups.min.js" type="text/javascript"></script>
          <script src="resources/splitbuttons/ej2-splitbuttons.min.js" type="text/javascript"></script>

          <!-- JavaScript (ES5) SpeechToText's control global script -->
          <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
       </head>
       <body>
       </body>
  </html>

Step 5: Now, add the SpeechToText element and initiate the JavaScript (ES5) SpeechToText control in the index.html by using following code

[src/index.html]

<!DOCTYPE html>
  <html xmlns="http://www.w3.org/1999/xhtml">
       <head>
          <title>JavaScript (ES5)</title>
          <!-- JavaScript (ES5) SpeechToText's dependency style -->
          <link href="resources/base/material.css" rel="stylesheet" type="text/css"/>
          <link href="resources/buttons/material.css" rel="stylesheet" type="text/css"/>
          <link href="resources/popups/material.css" rel="stylesheet" type="text/css"/>

          <!-- JavaScript (ES5) SpeechToText's control style -->
          <link href="resources/inputs/material.css" rel="stylesheet" type="text/css"/>

          <!-- JavaScript (ES5) SpeechToText's dependency global script -->
          <script src="resources/base/ej2-base.min.js" type="text/javascript"></script>
          <script src="resources/buttons/ej2-buttons.min.js" type="text/javascript"></script>
          <script src="resources/popups/ej2-popups.min.js" type="text/javascript"></script>
          <script src="resources/splitbuttons/ej2-splitbuttons.min.js" type="text/javascript"></script>

          <!-- JavaScript (ES5) SpeechToText's control global script -->
          <script src="resources/inputs/ej2-inputs.min.js" type="text/javascript"></script>
       </head>
       <body>
            <!-- Add the HTML <div> element  -->
            <div id="container">
                <button id="speechtotext_default"></button>
            </div>
            <script>
                // Initializes the SpeechToText control
                var speechToText = new ej.inputs.SpeechToText({});

                // Render initialized SpeechToText.
                speechToText.appendTo('#speechtotext_default');
            </script>
       </body>
  </html>

Step 6: Now, run the index.html in web browser, it will render the Syncfusion JavaScript (ES5) SpeechToText control.

Step 1: Create an app folder quickstart for getting started.

Step 2: The JavaScript (ES5) control’s global scripts and styles are already hosted in the below CDN link formats.

Syntax:

Dependency Script: https://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Control Script: https://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/dist/global/{PACKAGE_NAME}.min.js

Dependency Styles: https://cdn.syncfusion.com/ej2/{DEPENDENCY_PACKAGE_NAME}/styles/material.css

Control Styles: https://cdn.syncfusion.com/ej2/{PACKAGE_NAME}/styles/material.css

Example:

Script: https://cdn.syncfusion.com/ej2/ej2-inputs/dist/global/ej2-inputs.min.js

Styles: https://cdn.syncfusion.com/ej2/ej2-inputs/styles/material.css

Step 3: Create a HTML page (index.html) in ~/quickstart/index.html location and add the CDN link references. Now, add the SpeechToText element and initiate the JavaScript (ES5) SpeechToText control in the index.html by using following code.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

  <script src="https://cdn.syncfusion.com/ej2/29.1.33/ej2-inputs/dist/global/ej2-inputs.min.js" type="text/javascript"></script>

  <!--style reference from app-->
  <link href="index.css" rel="stylesheet" />
<script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js" type ="text/javascript"></script>
</head>

<body>
  <!--Element to render the SpeechToText control-->
  <div id="container">
    <button id="speechtotext_default"></button>
    <textarea id="textareaInst"></textarea>
  </div>
  <script>
    // Initializes the SpeechToText control
    var speechToText = new ej.inputs.SpeechToText({
      transcriptChanged: (args) => {
        textareaObj.value = args.transcript;
      }
    });

    // Render initialized SpeechToText.
    speechToText.appendTo('#speechtotext_default');

    var textareaObj = new ej.inputs.TextArea({
      rows: 5,
      cols: 50,
      value: '',
      resizeMode: 'None',
      placeholder: 'Transcribed text will be shown here...'
    });
    textareaObj.appendTo('#textareaInst');
  </script>
  <script>
    var ele = document.getElementById('container');
    if (ele) {
      ele.style.visibility = "visible";
    }
</script>
<style>
  #container {
    margin: 50px auto;
    gap: 20px;
    display: flex;
    flex-direction: column;
    align-items: center;
  }
</style>
</body>

</html>

Step 4: Now, run the index.html in web browser, it will render the Syncfusion JavaScript SpeechToText control.

The SpeechToText control requires an internet connection and using a browser that supports SpeechRecognition from the Web Speech API.

Adding button content

You can use the content property to display the start listening text and stopContent to display the stop listening text by using the buttonSettings property.
