Creating Spanish language lessons for mobile application

I have an AI voice agent that speaks Spanish using predefined scripts. The goal is to make its speech sound as natural and human as possible. Your task is to have conversations with the AI and identify any issues that make it sound unnatural, including logic, grammar, syntax, pronunciation, filler words, pauses, intonation, or any other nuances. For each issue, you'll provide the exact phrase spoken by the bot, classify the issue (e.g. logic, syntax, pronunciation, pauses, intonation), and suggest a natural Spanish alternative. We then update the script and repeat the process until the conversation reaches production quality. The final version is reviewed by another native Spanish speaker before deployment. There are several call scenarios available, and more will be added over time. You'll also have access to a web interface where you can edit prompts, launch calls yourself, and test improvements directly. Compensation is flexible and can be hourly or task-based, depending on the assignment. In addition, performance bonuses are available if the final version performs well in real customer calls with a low AI detection rate.
