Abstract
The present disclosure discloses a method and apparatus for training an acoustic model. A specific implementation of the method comprises: removing a high-delay search path from all search paths used in training an acoustic model by using a connectionist temporal classification (CTC) criterion, the high-delay search path being a search path whose state output delay greater than a delay threshold; and training the acoustic model on the basis of a search path whose state output delay smaller than the delay threshold.

A method for training an acoustic model, comprising:
- removing a high-delay search path from all search paths used in training an acoustic model by using a connectionist temporal classification (CTC) criterion, the high-delay search path being a search path having a state output delay greater than a delay threshold;
- and
- training the acoustic model using search paths among the all search paths having the state output delay smaller than the delay threshold and other than the high-delay search path.
An apparatus for training an acoustic model, comprising:
- at least one processor;
- and
- a memory storing instructions, the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
- removing a high-delay search path from all search paths used in training an acoustic model by using a connectionist temporal classification criterion, the high-delay search path being a search path having a state output delay greater than a delay threshold;
- and
- training the acoustic model using search paths among the all search paths having the state output delay smaller than the delay threshold and other than the high-delay search path.
A non-transitory computer medium, storing a computer program, wherein the program, when executed by a processor, causes the processor to perform operations, the operations comprising:
- removing a high-delay search path from all search paths used in training an acoustic model by using a connectionist temporal classification (CTC) criterion, the high-delay search path being a search path having a state output delay greater than a delay threshold;
- and
- training the acoustic model using search paths among the all search paths having the state output delay smaller than the delay threshold and other than the high-delay search path.
