I want learners to take part in a conversation by recording their voices and listening to the recorded dialogue.

On my wordpress website, I will provide model dialogues by native speakers for learners to improve their speaking skills.

I want the users to:

1. listen to the model dialogue between A and B.

2. Enact the dialogue with A or B by saying the line and recording their voice.

3. Listen to the recorded dialogue.

How is this possible?

Thanks.
