I have sent several emails to Rosetta Stone in regards to how their program either has slides with pronunciation exercises that done ever acknowledge a person speaking or slides that you can say something barely close to what you are asked to say and get a perfect score on.
I paid for a 6 month subscription to learn Mandarin and immediately regretted it. My last email included a video where the program asked me to say Dian Hua, the mandarin words for telephone (tones not shown) and I got perfect pronunciation score for saying Leann Ma.
I tried the program years ago on my laptop and it was littered with errors and malfunctions. I thought it might have improved after so long but it seems worse. Furthermore, nothing has been updated or improved.
The claim they have fixed an error I inform them of but they to nothing to be proactive in refining, improving or even doing quality control on their product. It is a sloppily made, I maintained, mess that makes it difficult to learn.
I speak words and phrases to a friend who is came to Canada from China and Rosetta Stone gives the impression I have perfected these phases but my friend says I am not even close. The program leaves a person feeling over confident until the talk to someone and then they feel like a fool.
Reading professional reviews online I am seeing a continuing narrative that people become frustrated and stop using Rosetta Stone, it uses poor methods to teach and its claims are just shy of fraud.
I recommend you try a different program, I’m going to look for one.
