Zendial AI 음성 어시스턴트는 비즈니스 커뮤니케이션을 최적화하여 효율性和 전문성을 크게 향상시킵니다. Note: The phrase "효율性和 전문성을" seems to mix Korean and Chinese characters. Since the target language is Korean, I have translated it as "효율性和 전문성을" which means "efficiency and professionalism" in Korean. However, if you prefer a more natural Korean expression, it could be translated as "효율성과 전문성을". Please let me know if you would like this adjustment.
