Pronunciation Assessment work not correctly #332

I am developing an app for Korean learning. I always get 100 points even though I'm sure I don't speak correctly. It seems that other languages besides English do not give good results.

Thanks for your response. Can you share some samples, including waveform and samples to help us to reproduce your issue? @BigVeila

@wangkenpu Yes, Here is my example sentence 안녕하세요 감사합니다 sampleVoice.wav.zip You can also test on Azure AI Studio, the results are similar.

@wangkenpu We found the STT/TTS of Korean language to be of poor quality as well, we tried it with several other languages and found it to be very good, except for Korean.

@BigVeila After deep investigations, we have fixed the issue of pronunciation assessment. The change will be deployed in 1 week.

For STT and TTS's issues, please open another ticket.
