Claim 23:
24. A speech recognition apparatus, comprising:
at least one processor; and
at least one memory configured to store instructions to be executed by the at least one processor and a neural network,
wherein the at least one processor is configured to, based on the instructions:
output an input activation map from speech data representing a word;
perform an inference operation by implementing a current convolutional layer of the neural network provided the input activation map to generate an output activation map, where a kernel weight of the current convolutional layer is a weight quantized to a representation bit number from a trained kernel weight for the current convolutional layer;
output another activation map that includes activations that are activation results, of the current convolutional layer, quantized to a second representation bit number by quantizing the output activation map within a range represented by an activation quantization parameter that includes first and second parameters; and
perform a word recognition process by processing the other activation map,
wherein the first parameter is dependent on first and second thresholds derived from the output activation map, and the second parameter is dependent on the first and second thresholds, and
wherein the quantization of the activation results is dependent on the first parameter and the second parameter.
