12/29/2023 0 Comments Speech to text converter in jsIf any error occurs during this process, our application will inform the user via the instruction box. We also created the onerror event handler triggered when an error occurs while transcribing the speech. If you click the Start button, you will see that it will automatically convert whatever you speak into text and fill the transcribed text inside the textbox. In this function, we will fetch the transcript of the speech given to us by the event.results variable, then update our previous content variable and textarea with the new results. This event is triggered when the recognition API has successfully converted speech from the user’s microphone to text, and the data is made available via the event.results variable. Next, we will write code for the onresult event handler. Here, we programmed our application to inform the user that voice recognition is on and converts speech to text. The onstart event handler is triggered when the recognition API starts and has microphone access. They are onstart, onspeechend, onerror, and onresult. We also added a couple of event handlers to the recognition object to bring our application to life. When you press the button, your browser will request permission to use your microphone, as shown in the image below. When this happens, the recognition API is begun and will listen for input from the user. We created an event handler triggered whenever the user clicks on the Start button to start recognizing. Thus, we are making the API continuously listen for input from the user’s microphone. We then set the continuous variable of the recognition object to true. We are initializing it to an empty string because we have not converted anything yet. We also created a content variable that keeps track of text the application has converted and displayed in the textarea from the HTML file. In the code above, we invoked the Web Speech Recognition API and initialized an instance stored in the recognition variable.Īfter this, we made references to our #textbox and #instructions elements we defined in the HTML using JQuery to control them from our code. Reach out to me if you encounter any issues or have any questions.Enter fullscreen mode Exit fullscreen mode I hope this gave a good idea to explore browser API's in Pega applications and would like to hear other interesting use cases you applied this API in. It is just a sample to get started with, this speech recognition can be applied to wide range of use cases in Pega workflows and in non pega applications as well. To stop the speech recognition, just click on Stop button. Make sure this permission is granted.Īt this point, browser will capture your speech and convert it to text and assign this text to textarea in Pega pulse section. When the start button is clicked for the first time, browser will ask permission for microphone. Save all the rules and test the functionality. Get the code from this Gist and paste in the javascript file and save the rule. js file in scripts and styles tab of container harness rule. Provide a tour id of value 'pulseNote' to textarea field in Pega pulse section.Ĭreate a javascript binary file in Pega and include this. Give Tour ID's to these two buttons and labels. Add two empty labels in the same section. These buttons will activate and deactivate speech recognition. Modify Pega pulse section and include two buttons 'Start' and 'Stop'. Steps to configure speech recognition API These functions will convert speech into text and assign the text to textarea in Pulse section. This file will contain functions and logic to invoke speech recognition API. To learn more about this API, please check this MDN Documentationįor this use case we need a javascript file. We will be using Web speech API for this use case. We shall modify Pega pulse in such a way that it takes notes by listening to user. Let us see how we can implement this speech recognition API With speech recognition API, use cases like taking a note, drafting an email etc. It is important to incorporate the latest technologies into the application to make the user experience better. Pega applications have evolved and are being used on all kinds of devices - desktop, tablets, mobile etc.
