3. The automatic speech recognition system of claim 2 , wherein the first acoustic model is a first process of establishing a statistical representation for feature vector sequences computed from a speech waveform of the input speech, and wherein the second acoustic model is a second process of establishing a statistical representation for feature vector sequences computed from a speech waveform of the input speech different from the first process.
2. The automatic speech recognition system of claim 1 , 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 language model and a first acoustic 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 language model and a second acoustic model, and wherein the first acoustic model is different from the second acoustic model.
