how to stop vapi from talking when user try to say something?
v
@Aviad To stop VAPI from talking when the user tries to say something, you can listen for an event that indicates the user has started speaking. When this event is detected, you can then call a method to interrupt VAPI's speech. Here's how you can set this up: 1. Listen for the user's speech start event. 2. When the event is triggered, call a method to stop VAPI from speaking. Would you like me to set up this event listener for you?
You can continue this conversation by mentioning me in the message.

@Vapi yes please, how can i do that in node js?
v
@Aviad In Node.js, you would typically use a speech recognition library to detect when the user starts speaking and a text-to-speech (TTS) library to control VAPI's speech. Here's a general approach to achieve this: 1. Use a speech recognition library like
node-speech-recognition
to detect when the user starts speaking. 2. Use a TTS library or VAPI's built-in methods to control speech output. Here's a pseudo-code example to illustrate the concept:
Copy code
javascript
const speechRecognition = require('node-speech-recognition');
const tts = require('your-tts-library'); // Replace with your actual TTS library

// Initialize speech recognition
const recognizer = new speechRecognition.Recognizer();

// Function to stop VAPI from speaking
function stopSpeaking() {
  // Call the method from your TTS library to stop speech
  tts.stop();
}

// Start listening for the user's speech
recognizer.startListening();

// Event listener for when the user starts speaking
recognizer.on('speechStart', () => {
  // User started speaking, stop VAPI from talking
  stopSpeaking();
});

// Your TTS function to make VAPI speak
function vapiSpeak(text) {
  // Call the method from your TTS library to start speech
  tts.speak(text);
}

// Example usage
vapiSpeak('Hello, how can I assist you?');
Please note that you'll need to replace
'your-tts-library'
with the actual library you're using for text-to-speech, and implement the
stop
and
speak
methods according to that library's API. Remember to install the necessary Node.js packages for speech recognition and TTS, and ensure that they provide the functionality to start and stop speech as needed. If you need more specific help with the libraries you're using, please provide their names, and I can give you more detailed instructions.

@Vapi i am using @vapi-ai/web
v
@Aviad Great! If you're using
@vapi-ai/web
, you should have access to methods that control the speech synthesis and recognition directly through the VAPI interface. Here's a general approach using the
@vapi-ai/web
library: 1. Initialize VAPI and configure the speech recognition to start listening. 2. Use the
interrupt()
method to stop VAPI from speaking when the user starts talking. Here's a basic example in JavaScript:
Copy code
javascript
import VAPI from '@vapi-ai/web';

// Initialize VAPI
const vapi = new VAPI();

// Function to handle user's speech start
function onUserStartsSpeaking() {
  // Interrupt VAPI's speech
  vapi.interrupt();
}

// Configure VAPI's speech recognition to call onUserStartsSpeaking when the user starts speaking
vapi.on('speechStart', onUserStartsSpeaking);

// Start VAPI's speech recognition
vapi.startListening();

// Function to make VAPI speak
function vapiSpeak(text) {
  vapi.speak(text);
}

// Example usage
vapiSpeak('Hello, how can I assist you?');
Make sure to replace the placeholder functions and event names with the actual ones provided by the
@vapi-ai/web
library. The
interrupt()
method is a hypothetical example; you will need to refer to the library's documentation for the exact method to stop speech synthesis. If the
@vapi-ai/web
library does not provide a direct method to interrupt speech, you might need to implement a custom solution or check if the library has an event system that allows you to detect when the user starts speaking and then stop the speech synthesis accordingly. If you need further assistance with the specific methods and events provided by
@vapi-ai/web
, please refer to the library's documentation or ask support for more info on this.

@Vapi Property 'interrupt' does not exist on type 'Vapi'.ts(2339)
v
@Aviad I apologize for the confusion. It seems that the
interrupt
method I mentioned does not exist in the
@vapi-ai/web
library. To properly handle this in the
@vapi-ai/web
library, you would need to use the correct methods provided by the library to stop the speech output when the user starts speaking. Since I don't have the exact details of the
@vapi-ai/web
library's API, I recommend checking the library's documentation for methods related to stopping or pausing speech synthesis. Typically, such libraries would provide a method to stop the current speech output. If the library provides an event listener for detecting when the user starts speaking, you could use that event to trigger the stopping of the speech synthesis. If there's no such method or event in the library, you might need to implement additional logic to manage the speech state or look for an alternative solution. For accurate and specific instructions, please refer to the
@vapi-ai/web
library's documentation or contact their support for more information on how to interrupt or stop ongoing speech when the user starts speaking.

Hey @Aviad To help track down this issue, could you share: - The call ID - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help me figure out what went wrong!
