Wakeup words support for Chinese

[juncaofish]

Hello,
Just need a local support feature for voice wakeup~
I notice this file respeaker/pocketsphinx-data/dictionary.txt .
So my question is if I want to set a customised wakeup word in Chinese, like "魔镜", can I add to the dictionary something like 'mojing' M UE J IN ?
Thanks.

To recognize Chinese words, you need another acoustic model, for example
https://sourceforge.net/projects/cmusphinx/files/Acoustic%20and%20Language%20Models/Mandarin/.

But the mandarin acoustic model is not good enough. You may need some training for the model.

Thanks for replying.
So is MT7688 capable enough to run the mandarin acoustic model?

[xiongyihui]

The mandarin acoustic model is too big for MT7688 to do continuous speech recognizer. You need a small one.

I find a tool https://github.com/Kitt-AI/snowboy which seems to be a perfect solution for Chinese hotword local detection. However, it seems it cannot be targeted to MT7688 either for the hardware architecture limit. Do you have any suggestions on how to take less effort for Chinese hotword detection task? Thanks very much.

It seems the snowboy is the most accurate. Ask for kitt-ai to compile a MIPS version of snowboy maybe work. There are old reversions of mandrarin acoustic model in cmusphinx repo which is smaller and should be able to run on MT7688, or train a smaller model by hand.

I'm afraid the MT7688 is not a supported target for snowboy. Take a reference at discussion here: https://groups.google.com/a/kitt.ai/forum/#!topic/snowboy-discussion/iL4rRZRUk4U

is it possible to use Xunfei wakeup on Respeaker, I mean compile the sdk for 7688's mips platform? It seems like a good solution if cost is not considered as a cons.

[xiongyihui]

I applied a sdk of xunfei's stt and stt running on 7688, it worded. The wakeup sdk should work too.

[juncaofish]

Since I have tried the online sdk on Raspberry Pi, I guess you mean the online tts/stt service of xunfei. Do you need to submit the compile chain to their engineer? I remember the sdk only provides .so for x86/x64 .

[xiongyihui]

Yes, for c sdk for 7688, we need to submit the toolchain.

I am intersted in using xunfei's wakeup sdk.... i have download the pack from there, and how can i use it in respeaker?

yihui 你好
我在mac上执行bing_translator.py的时候，提示DEBUG:urllib3.connectionpool:https://oxford-speech.cloudapp.net:443 "POST /token/issueToken HTTP/1.1" 401 143

Is there any way to actually run snowboy detect on 7688, if so how? Thanks
