Abstract
Disclosed herein is an artificial intelligence apparatus for recognizing speech of a user including a microphone and a processor configured to obtain, via the microphone, speech data including speech of a user, determine a frequency weight for each word using a speech recognition log, generate a speech recognition result corresponding to the speech data using the frequency weight, and perform control corresponding to the speech recognition result.
Claims18
An artificial intelligence apparatus for recognizing speech of a user, comprising:
- a microphone;
- and
- a processor configured to:
- obtain, via the microphone, speech data including speech of a user,
- for each of a plurality of sections of the speech data:
- calculate a probability for each of a plurality of words,
- determine, using a speech recognition log, a frequency weight for each of the plurality of words,
- for each of the plurality of words, calibrate the probability by multiplying the calculated probability by the determined frequency weight,
- convert the speech data into text by (i) selecting, for each section of the plurality of sections, a word having a highest calibrated probability and (ii) combining the selected words, and
- perform control based on the text.
A computer-implemented method of recognizing speech of a user, the method comprising:
- obtaining, via a microphone, speech data including speech of a user,
- for each of a plurality of sections of the speech data:
- calculating a probability for each of a plurality of words,
- determining, using a speech recognition log, a frequency weight for each of the plurality of words,
- for each of the plurality of words, calibrating the probability by multiplying the calculated probability by the determined frequency weight,
- converting the speech data into text by (i) selecting, for each section of the plurality of sections, a word having a highest calibrated probability and (ii) combining the selected words, and
- performing control based on the text.
A non-transitory processor-readable medium having recorded a program for performing a method of recognizing speech of a user, the method comprising:
- obtaining, via a microphone, speech data including speech of a user,
- for each of a plurality of sections of the speech data:
- calculating a probability for each of a plurality of words,
- determining, using a speech recognition log, a frequency weight for each of the plurality of words,
- for each of the plurality of words, calibrating the probability by multiplying the calculated probability by the frequency weight,
- converting the speech data into text by (i) selecting, for each section of the plurality of sections, a word having a highest calibrated probability and (ii) combining the selected words, and
- performing control based on the text.
