Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 19:
20. A non-transitory machine-readable medium containing instructions that when executed cause at least one processor of an electronic device to:
perform feature extraction of input audio data to identify extracted features associated with the input audio data;
detect a language associated with the input audio data by processing the extracted features using a plurality of language models, each language model associated with a different language; and
direct the input audio data to one of a plurality of automatic speech recognition (ASR) models based on the language associated with the input audio data;
wherein the instructions that when executed cause the at least one processor to detect the language associated with the input audio data comprise instructions that when executed cause the at least one processor to:
use each language model to determine a probability that the input audio data is from a particular language;
concatenate the probabilities determined using the language models; and
process the concatenated probabilities using a neural classification model; and

wherein the instructions that when executed cause the at least one processor to process the concatenated probabilities using the neural classification model comprise instructions that when executed cause the at least one processor to:
process the concatenated probabilities using a plurality of temporal convolutional neural networks, wherein outputs from at least one of the temporal convolutional neural networks are normalized;
average outputs or normalized outputs from a last of the temporal convolutional neural networks; and
determine probabilities that specific languages are associated with the input audio data based on the averaged outputs.
