Linguistic model selection for adaptive automatic speech recognition

An adaptive automatic speech recognition (ASR) device comprising:

• a sound input to receive a speech input;
• a biometric input to receive a biometric signal;
• an biometric processor in communication with the biometric input to:
• receive the biometric signal;
• identify a linguistic model based on the biometric signal;
• and
• a speech recognition module to process the speech input for speech recognition using the identified linguistic model.

A method comprising:

• receiving a speech signal;
• receiving a biometric signal from a biometric sensor implemented at least partially in hardware;
• determining a linguistic model based on the biometric signal;
• and
• processing the speech signal for speech recognition using the linguistic model based on the biometric signal.

A system comprising:

• an adaptive automatic speech recognition device comprising:
• a sound input to receive a speech input;
• a biometric input to receive a biometric signal;
• a biometric processor in communication with the biometric input to:
• receive the biometric signal;
• ad
• identify a linguistic model based on the biometric signal;
• a speech recognition modules to:
• process the speech input for speech recognition using the identified linguistic model;
• and
• a dialog system comprising:
• a parser module to convert the recognized speech into an instruction;
• and
• an intent classifier module to determine a command to execute on the system based on the instruction.
