Hello Kmaclean,

    The tutorial said it should keep 48000Hz when recording. Can I use 8kHz instead?

    That's the only difference between tutorial's and my setting.

Must I keep 48000Hz for recroding? Why?

Hello Zoe,

    I haven't solved this problem yet. Kmaclean suggested me to use VoxForge tutorial to record my data again and uploaded it.

    I am not sure whether it works or not. And I haven't found the essential different recording step(s) between tutorial's and mine.

    I have no idea at all:( I hope to solve this problem as well. It's so wired. I hope anyone can help us....

   Sorry about that for both of us:(

Yes, you can use 8kHz;

or you can record at 48kHz and downsample using a utility like sox. 

Note: the audio used for AM training must all be the same sampling rate.

Thanks kmaclean.  Do you know what the end-point detection algorithm in HTK? I have used dual-threshold detection, but the result is not good...

HELLO Nancy:

I'm trying to process music files using HTK. And I have the same problems as yours.

D:\htk>HCompV -C configz -f 0.01 -m -S flist.scp -M data/hmm0 proto
ERROR [+6251] Input file is not in RIFF format
ERROR [+6213] OpenWaveInput: Get[format]HeaderInfo failed
ERROR [+6313] OpenAsChannel: OpenWaveInput failed
ERROR [+6316] OpenBuffer: OpenAsChannel failed
ERROR [+2050] LoadFile: Config parameters invalid
FATAL ERROR - Terminating program HCompV

I have a database consisting 500 songs of mp3 format. And I convert them to wav. When I run HCopy , no error happened.

I've been working on this problem the whole day and haven't work it out yet!

Hello Zoe,

    Have you solved the problem?

No，I haven't。 €‚My friend give me some new recorded WAV music. The error remains the same.

I know it. I changed 3 record equipments, including Audacity, Matlab, and Windows Recorder, the error still exists. I doubt that HTK cannot process wav file, but only sig format.

If you are very hurry, I think you need use HSLab to record your data again.

Anyway, could you please let me know if you solved the problem?

Many thanks!!

Hi, I had the same problem running Hlab tool. The solution was running Hlab with -F WAV option. Like this:

Hlab -F WAV chair01.wav
