Question

我尝试使用MSR Identity toolkit运行演示人员验证演示人。然而，在训练UBM步骤后它留下了错误。错误如下。看起来fopen返回-1并导致错误fread。我无法理解为什么它无法阅读filenames。我无法附加代码，因为它涉及许多功能。我希望熟悉这个工具包的人可以帮助我。

Error using fread
Invalid file identifier. Use fopen to generate a valid file identifier.

Error in htkread (line 7)
nframes = fread(fid, 1, 'int32'); % number of frames

Error in mapAdapt>load_data (line 107)
    data{ix} = htkread(filenames{ix});

Error in mapAdapt (line 52)
    dataList = load_data(dataList);

Error in demo_gmm_ubm (line 69)
    gmm_models{spk} = mapAdapt(spk_files, ubm, map_tau, config);

导致错误的部分代码如下：

function data = load_data(datalist)
% load all data into memory
if ~iscellstr(datalist)
    fid = fopen(datalist, 'rt');
    filenames = textscan(fid, '%s');
    fclose(fid);
    filenames = filenames{1};
else
    filenames = datalist;
end
nfiles = size(filenames, 1);
data = cell(nfiles, 1);
for ix = 1 : nfiles,
    data{ix} = htkread(filenames{ix});
end

function [data, frate, feakind] = htkread(filename)
% read features with HTK format (uncompressed)
fid = fopen(filename, 'r','b'); %ERROR HERE
nframes = fread(fid, 1, 'int32'); % number of frames
frate   = fread(fid, 1, 'int32'); % frame rate in nano-seconds unit
nbytes  = fread(fid, 1, 'short'); % number of bytes per feature value
feakind = fread(fid, 1, 'short'); % 9 is USER
ndim = nbytes / 4; % feature dimension (4 bytes per value)
data = fread(fid, [ndim, nframes], 'float');
fclose(fid);

datalist包含：

'features\fadg0_sa2.htk'
'features\fadg0_si1279.htk'
'features\fadg0_si1909.htk'
'features\fadg0_si649.htk'
'features\fadg0_sx109.htk'
'features\fadg0_sx19.htk'
'features\fadg0_sx199.htk'
'features\fadg0_sx289.htk'
'features\fadg0_sx379.htk'

Answer 1

幸运的是，我毫无疑问地使用了MSR Identity Toolkit。

我在htkread.m中的内容如下：

...

fid = fopen（文件名，＆＃39; rb＆＃39;，＆＃39; ieee-be＆＃39;）;

nframes = fread（fid，1，＆＃39; int32＆＃39;）; ％帧数

...

您遇到的错误可能来自：

big-endian / little-endian问题
您缺少* .htk功能
* .htk采用其他格式

的问候，

Answer 2

你的fid是否会返回负值？如果是，请尝试指定dataList =＆＃39; ubm.lst＆＃39 ;;在代码中

MSR Identity工具包中的错误（fopen）
