10. The automatic speech recognition system of claim 9 , wherein the first ASR engine is further configured to translate the input speech of the language into the first translated text according to the first acoustic model and a first language model, wherein the second ASR engine is further configured to translate the input speech of the language into the second translated text according to the second acoustic model and a second language model, and wherein the first language model is different from the second language model.
9. An automatic speech recognition system comprising: an input interface configured to receive input speech; a pre-processor configured to determine a language of the input speech and, based on the language of the input speech, select from among a plurality of automatic speech recognition engines configured to recognize speech of different languages, only those automatic speech recognition engines configured to recognize the language of the input speech including: a first automatic speech recognition (ASR) engine configured to translate the input speech of the language into text according to a first acoustic model, and output first translated text that is translated from the input speech according to the first acoustic model and a first confidence score indicating a degree of accuracy of translating the input speech into the first translated text according to the first acoustic model; a second ASR engine configured to translate the input speech of the language into text according to a second acoustic model, and output second translated text that is translated from the input speech according to the second acoustic model and a second confidence score indicating a degree of accuracy of translating the input speech into the second translated text according to the second acoustic model; and a comparator configured to compare the first confidence score and the second confidence score, and output a most accurate representation of the input speech from among the first translated text and the second translated text based on a result of the comparison, wherein the first acoustic model is different from the second acoustic model.
