Very low accuracy

[zyc1310517843]

Hello, I downloaded the official Chinese speech model. It seems that the recognition rate is very low and the basic recognition is not correct. Thank you for your guidance.

Where did you download the official Chinese package? If the recognition rate is low, you need to get tools like dictionary models yourself

I think he downloaded this model:
https://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/Mandarin/

I am also using this model. The dictation accuracy of this model is indeed very poor. In dictation mode, it can hardly generate any readable sentences. I can only get some unrelated fragments of words.

But if a JSGF grammar file is loaded, the accuracy is acceptable. Note: It seems that manual word segmentation is required for Chinese grammar file, that is, adding spaces between each word in the sentence. Otherwise, The dictionary is missing a phonetic transcription for the word 'xxxxxxxxxxxxxxxxxx' will be reported and you will not be able to identify any content.

Or we can make some adjustments to the acoustic model or configuration to improve the accuracy of dictation.
