Sparring — Practice Tough Customer Conversations

Sales and support teams need a safe place to practice difficult conversations before a real customer is on the line. Sparring is a browser-based voice role-play for small Spanish-speaking teams. Choose a scenario such as a delayed delivery, a price objection, or a cancellation request, then speak with a simulated customer who asks follow-up questions and challenges vague answers. AssemblyAI's Voice Agent API handles the spoken interaction. Sparring checks each finalized trainee turn against the scenario rubric, validates exact quotes as evidence, and calculates a weighted score in real time. The interface shows how much of the rubric was observed and gives one focused next step to practice again. The scenarios use fictional customers and explicit policy limits, so the trainee can rehearse useful responses without making commitments to real people. Scores are formative guidance, not a certification. The public repository includes the specification, tests, architecture, and known limitations.
