Speaker Normalization Parameter Generation Problem

[Arunasish Sen]

Hi Andrew,

I am a Research Engineer @ Xerox Research Center India. I was trying to annotate some switchboard data with autobi
While trying to normalize speaker data for a conversation side, the generated values for F0 and intensity are both 0.0

The debug output is as follows:

1 [main] INFO edu.cuny.qc.speech.AuToBI.util.AuToBIUtils  - Successfully generated normalization parameters.
4 [main] INFO edu.cuny.qc.speech.AuToBI.util.AuToBIUtils  - Generated Parameters: f0: mean 0.0 - stdev 0.0
I: mean 0.0 - stdev 0.0

The commandLine is according to the manual given in the website.

java -cp AuToBI.jar edu.cuny.qc.speech.AuToBI.SpeakerNormalizationParameterGenerator -wav_files=SNfn -output_file=2005-A.snp -speaker_id=2005-A.snp

Can you provide a probable cause of this phenomenon?

Regards,
Arunasish

Hi Arunasish,

java -cp AuToBI.jar edu.cuny.qc.speech.AuToBI.SpeakerNormalizationParameterGenerator -wav_files=SNfn -output_file=2005-A.snp -speaker_id=2005-A.snp

What are you using for "SNfn" here?  this parameter is expecting the filename (with extension) to a wavefile (or pattern)

Hi Andrew,

Thanks for the reply, actually 'SNfn' that was the file containing the file-names. I figured out the problem later on. It was a data precision error from java. AuToBI can process only 16 bit signed Integer PCM data. we were providing it with unsigned integer data, which was causing it throw an exception and not process the wav file, resulting in 0 values.
