The narration pronunciation sounds strange

In the case of AI Voice, we use engines from third-party services (Google/Naver, etc.). Our experience shows that engines are often upgraded through learning, but sometimes errors occur when reading certain phrases strangely. When such cases are detected, we provide feedback to the service provider, but due to the characteristics of AI implementation, it is impossible to manually correct these errors. The improvement is done through relearning over time, and thus, processing may take longer. The best solution is to temporarily avoid the problematic pronunciation by modifying the text.
