_thread & speech_recognizer

[deby13]

Trying to use the example for speech recognition, I get 2 errors
1- does not find _thread
2- does not find speechrecognizer
as the program tries to import speechrecognizer from modules. I checked the modules with Putty.

Accessing Maixduino with Putty and typing command help('modules') I see 2 modules and 2 math, I`m wondering if this is not causing the issue with speech.
Were I can find _thread modules. I have searched all over and could not find it
I would very much appreciate your help. Thanks
