Wrong result decoding with test.c on Windows

[opentld]

platform: windows10, vs2019 when running tect.c, error occurs:

what does these mean? @proger @camillem @dremendes @Sharcoux @hviana

Did you build libvosk yourself with mkl or you use our prebuilt binary

I build libvosk with Kaldi & openBlas...

I use the libvosk.dll official release for chinese speech, the results seems wrong:

Hi

Probably data is wrong. Please share the audio file you are trying so we can reproduce.

Because wav format is not supported, so I named the extension wav as mp4, you can change the extension back to wav

Thank you very much !

I get "绿 是 阳春 烟 酒 大块 文章 的 底色 四月 的 凌乱 更是 绿 的 鲜活 秀媚 诗意 盎然" for your file which is probably close. Maybe it is charset issue. Try to save to a file and open with a notepad. Encoding should be UTF-8.

[opentld]

I use this function to decoding UTF-8 to string, it works!

std::string UTF8ToString(const std::string& utf8Data) { std::wstring_convert<std::codecvt_utf8<wchar_t>> conv; std::wstring wString = conv.from_bytes(utf8Data); // utf-8 => wstring

std::wstring_convert<std::codecvt< wchar_t, char, std::mbstate_t>>
    convert(new std::codecvt< wchar_t, char, std::mbstate_t>("CHS"));
std::string str = convert.to_bytes(wString);     // wstring => string

return str;

}

But, another question, it seems that the official libvosk.dll was not build with CUDA, would you please provide a GPU release? Thanks a lot !

@nshmyrev

[nshmyrev]

We do not support GPU on windows, it is more for linux server which needs to process hundreds of streams in parallel. You'd better use it with prebuilt docker.

In my experience, compiling vosk with kaldi CUDA is too difficult... :(

[nshmyrev]

We might consider building GPU packages some time in the future but no promises, sorry.

You have done so much for me, I really appreciate it! Thank you!
