For this very reason, hiring a tutor when learning to speak Chinese is absolutely necessary. In order to learn to speak Chinese properly, fluent speaking tutor can not only guide but can also help to accelerate learning.
When choosing a Chinese tutor, make sure to search for someone who is certified and experience in teaching Chinese. While a native speaker can provide help, someone who is trained to tutor will provide much more holistic language learning.
