How To Create ChatBot App in MIT App Inventor 2 | 12/100
Creating a chatbot app with speech recognition and text-to-speech capabilities is a fun and challenging project that can be accomplished using MIT App Inventor 2. With these components, users can interact with the chatbot using their voice, and the chatbot can respond back in a natural sounding voice. In this article, we will walk you through the process of creating a chatbot app with speech recognition and text-to-speech components in MIT App Inventor 2. Step 1: Setting Up the Interface The first step in creating a chatbot app in MIT App Inventor 2 is to set up the interface. This is the visual layout of the app that the user will interact with. You can create a basic interface using the designer tool in App Inventor. To create a simple chatbot interface, drag and drop two TextBox components and one Button component onto the screen. Step 2: Adding Speech Recognition Component The next step is to add the SpeechRecognizer component to the app. This component will enable the app to recognize the user's speech and convert it into text. To add the SpeechRecognizer component, click on the "Blocks" button at the top of the screen, then select the "Built-In" category, and drag the SpeechRecognizer component into the workspace. Step 3: Adding Text-to-Speech Component The TextToSpeech component will allow the app to respond to the user's input by speaking a response aloud. To add the TextToSpeech component, click on the "Blocks" button at the top of the screen, then select the "Built-In" category, and drag the TextToSpeech component into the workspace. Step 4: Writing the Code The final step in creating a chatbot app in MIT App Inventor 2 is to write the code that will enable the app to respond to user input. This is done using the Blocks Editor, which can be accessed by clicking on the "Blocks" button at the top of the screen. First, we will create a block that will trigger the SpeechRecognizer component when the user taps the "Speak" button. To do this, drag an "When Button.Click" block from the "Button" category onto the workspace. Then, drag a "SpeechRecognizer.StartListening" block from the "SpeechRecognizer" category and connect it to the "When Button.Click" block. Next, we will create a block that will convert the user's speech into text and display it in the first TextBox component. To do this, drag a "SpeechRecognizer.SpeechRecognized" block from the "SpeechRecognizer" category onto the workspace. Then, drag a "TextBox1.Text" block from the "TextBox" category and connect it to the "SpeechRecognizer.SpeechRecognized" block. Finally, we will create a block that will enable the app to respond to the user's input using text-to-speech. To do this, drag an "When TextBox1.AfterTextChanged" block from the "TextBox" category onto the workspace. Then, drag a "TextToSpeech.Speak" block from the "TextToSpeech" category and connect it to the "When TextBox1.AfterTextChanged" block. Inside the "TextToSpeech.Speak" block, enter the response that the chatbot should speak in response to the user's input. Step 5: Testing the App Once the code is written, the app can be tested on an Android device using the "Connect" button at the top of the screen. Make sure to enable the "Record Audio" permission in the device settings to use the speech recognition component. In conclusion, creating a chatbot app with speech recognition and text-to-speech capabilities in MIT App Inventor 2 is a fun and challenging project that can be accomplished with a little bit of coding Join this channel to get access to perks: https://www.youtube.com/channel/UCyNJURC5bvqIQ9vO9PBrYrA/join
