### Answer The error message you're encountering,

play() can only be initiated by a user gesture

, typically happens due to web browsers' policies to prevent videos and audios from playing automatically without a user interaction, like a click or a tap. To resolve this issue within the context of using the Vapi Web SDK, you should ensure that audio playback (like starting a conversation or speech synthesis) is triggered by some form of user action. This can be a button press or any other explicit interaction from the user. Here is a basic example of how you might adjust your implementation:

javascript
// Assuming you have a button with an id of 'startButton'
document.getElementById('startButton').addEventListener('click', function() {
    vapi.start("your-assistant-id");
    // This will ensure the audio starts only after user interaction
});

This approach adheres to the browsers’ autoplay policies by initiating the audio play through a user-triggered event, thus avoiding the error related to autoplay restrictions. Make sure to implement similar user-triggered interactions wherever you need to initiate audio playback or voice interactions in your application. This should help mitigate the issue across your web app when using the Vapi Web SDK.
