我已经训练了UBM模型,现在当我遇到以下错误时,我正在尝试实现说话人自适应。
例外:show enroll / something.wav不在HDF5文件中
我在文件“ feat”下有两个文件“ enroll”和“ test”,分别包含用于训练和测试的功能(.h5),并且我的enroll_idmap仅通过用于训练的音频(.wav)生成。而且,我的wav文件和feat文件是分开的。我认为我遇到了idmap问题。 “ enroll / something.wav”是我的enroll_idmap的rightid,但是“ HDF5文件”指的是什么?
谁能告诉我这个错误的含义以及如何解决?
这是我的enroll_idmap的代码
def __init__(self):
BASE_DIR = "./Database/sidekit_data"
self.AUDIO_DIR = os.path.join(BASE_DIR, "audio")
self.FEATURE_DIR = os.path.join(BASE_DIR, "feat")
self.TASK_DIR = os.path.join(BASE_DIR, "task")
def create_idMap(self, group):
# Make enrollment (IdMap) file list
group_dir = os.path.join(self.AUDIO_DIR, group) # enrollment data directory
group_files = os.listdir(group_dir)
group_models = [files.split('_')[0] for files in group_files] # list of model IDs
group_segments = [group+"/"+f for f in group_files]
# Generate IdMap
group_idmap = sidekit.IdMap()
group_idmap.leftids = np.asarray(group_models)
group_idmap.rightids = np.asarray(group_segments)
group_idmap.start = np.empty(group_idmap.rightids.shape, '|O')
group_idmap.stop = np.empty(group_idmap.rightids.shape, '|O')
if group_idmap.validate():
group_idmap.write(os.path.join(self.TASK_DIR, group+'_idmap.h5'))
else:
raise RuntimeError('Problems with creating idMap file')
然后,我得到带有以下内容的enroll_idmap和test_idmap:
create_idMap("enroll")
create_idMap("test")
这是说话者适应的代码,上面的错误在执行enroll_stat.accumulate_stat(…)时出现:
BASE_DIR = "./Database/sidekit_data"
enroll_idmap = sidekit.IdMap.read(os.path.join(BASE_DIR, "task", "enroll_idmap.h5"))
ubm = sidekit.Mixture()
model_name = "ubm_{}.h5".format(NUM_GUASSIANS)
ubm.read(os.path.join(BASE_DIR, "ubm", model_name))
server_eval = sidekit.FeaturesServer(feature_filename_structure="./Database/sidekit_data/feat/{}.h5",
...
...)
print("Compute the sufficient statistics")
enroll_stat.accumulate_stat(ubm=ubm,
feature_server=server_eval,
seg_indices=range(enroll_stat.segset.shape[0]),
num_thread=nbThread
)
这似乎不是什么大问题,但是它让我停了几天,请帮忙。
答案 0 :(得分:1)
我最终通过更改培训和测试功能的路径,使其在“ BASEDIR”之外得以解决
server_eval = sidekit.FeaturesServer(feature_filename_structure="./enroll/{}.h5",
...)
