Abstract
Methods and systems for recognizing speech include receiving information reflecting the speech, determining at least one broad-class of the received information, classifying the received information based on the determined broad-class, selecting a model based on the classification of the received information, and recognizing the speech using the selected model and the received information.
Claims22
A method for recognizing speech, comprising:
- receiving information reflecting the speech;
- determining at least one broad-class of the received information;
- classifying the received information based on the determined broad-class;
- selecting a model based on the classification of the received information;
- and
- recognizing the speech using the selected model and the received information.
3 more elements
A system for recognizing speech, comprising:
- a receiver for receiving information reflecting the speech;
- a first recurrent neural network for determining at least one broad-class of the received information;
- a second recurrent neural network for classifying the received information based on the determined broad-class;
- a model selector for selecting a Hidden Markov Model based on the classification of the received information;
- and
- a recognizer for recognizing the speech using the selected Hidden Markov Model and the received information.
3 more elements
A computer-readable medium containing instructions for a computer to perform the steps of:
- receiving information reflecting speech;
- determining at least one broad-class of the received information;
- classifying the received information based on the determined broad-class;
- selecting a model based on the classification of the received information;
- and
- recognizing the speech using the selected model and the received information.
