Ending a trial when a condition is met (or when a process finishes)

[steffejr]

Hello,
I am working on tasks that use browser-based voice recognition. I have a simple trial that asks the user to read a sentence. This sentence is listened to and compared back to what the user reads. Voice recognition works by listening, and when the user stops speaking, it performs the sentence comparison. I want my trial to end when that process is done. Is this possible?

I do not want a "Next" button that the user presses because they may press the button before the sentence is processed completely. And I do not want a timer since the voice recognition is cloud-based so it may be fast or slow depending on the internet connection.

Thank you

Hey @steffejr,

If you are writing your own plugin to handle this you can definitely do this. You just need to put the call to jsPsych.finishTrial in whatever function is invoked by the callback from the cloud API.

There's an example of doing this in my pipe plugin. I use await and wrap the plugin's run code in an async function. If you prefer other ways of asynchrony you can also make this work with a callback function in fetch or XMLHttpRequest.

Awesome, thank you. It worked.
