Abstract
A system and method for processing speech includes receiving a first information stream associated with speech, the first information stream comprising micro-modulation features and receiving a second information stream associated with the speech, the second information stream comprising features. The method includes combining, via a non-linear multilayer perceptron, the first information stream and the second information stream to yield a third information stream. The system performs automatic speech recognition on the third information stream. The third information stream can also be used for training HMMs.
Claims17
A method comprising:
- receiving, via a communication network, a first information stream associated with a formant frequency of speech, wherein the first information stream comprises micro-modulation features modeled in a first time scale;
- receiving, via the communication network, a second information stream associated with the speech;
- performing, via at least one hardware processor, automatic speech recognition on a third information stream formed by combining, via a non-linear multilayer perceptron, the first information stream and the second information stream, to yield a recognition result;
- and
- outputting, via the communication network, the recognition result comprising text representing the speech, the text being viewed on a display.
A system comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
- receiving, via a communication network, a first information stream associated with a formant frequency of speech, wherein the first information stream comprises micro-modulation features modeled in a first time scale;
- receiving, via the communication network, a second information stream associated with the speech;
- performing, via at least one hardware processor, automatic speech recognition on a third information stream formed by combining, via a non-linear multilayer perceptron, the first information stream and the second information stream to yield a recognition result;
- and
- outputting, via the communication network, the recognition result comprising text representing the speech, the text being viewed on a display.
