Abstract
A voice recognition apparatus includes: a first controller configured to acquire a voice signal of a user and acquire a phonebook list including at least one phonebook data piece in which a name and a phone number are matched from a user terminal; and a voice recognition engine to recognize the voice signal based on a voice recognition parameter, wherein the first controller is further configured to determine whether to change the voice recognition parameter value based on the phonebook list and change the voice recognition parameter value based on a determination result.
Claims17
A voice recognition apparatus comprising a first controller configured to:
- acquire a voice signal of a user and acquire a phonebook list including at least one phonebook data piece in which a name and a phone number match from a user terminal;
- recognize the voice signal based on a voice recognition parameter;
- and
- determine whether to change a value of the voice recognition parameter based on the phonebook list and change the value of the voice recognition parameter based on the determination result,
- wherein the first controller extracts at least one information of a number of total phonebook data pieces, a number of phonebook data pieces in which names are one word, or a number of phonebook data pieces in which names have similar pronunciations from the phonebook list, and determines whether to change the value of the voice recognition parameter based on the extracted at least one information.

A vehicle comprising:
- a communication device configured to receive a phonebook list including at least one phonebook data piece in which a name and a phone number are matched from a user terminal;
- a voice sensor configured to sense a voice uttered by a user and convert the voice into a voice signal;
- a voice recognition apparatus configured to:
- acquire the phone hook list of the user terminal received by the communication device;
- change a value of a voice recognition parameter based on the phonebook list;
- and recognize the voice signal based on the voice recognition parameter;
- and
- a main controller configured to transmit an operation command according to a voice recognition result of the voice recognition apparatus to the communication device,
- wherein the voice recognition apparatus extracts at least one information of a number of total phonebook data pieces a number of phonebook data pieces in which names are one word or a number of phonebook data pieces in which names have similar pronunciations from the phonebook list, determines whether to change the value of the voice recognition parameter based on the extracted at least one information, and changes the value of the voice recognition parameter according to the determination result.
6 more elements
A control method of a vehicle comprising steps of:
- confirming, by a controller, whether a vehicle and a user terminal are communicatively connected;
- acquiring, by the controller, a phonebook list including at least one phonebook data piece in which a name and a phone number are matched from the user terminal;
- changing, by the controller, a value of a voice recognition parameter based on the phonebook list;
- sensing, by the controller, a voice uttered by a user and converting the voice into a voice signal;
- recognizing, by the controller, the voice signal based on the voice recognition parameter to generate a voice recognition result;
- transmitting, by the controller, an operation command according to the voice recognition result;
- acquiring, by the controller;
- call history information from the user terminal;
- and
- applying, by a post processor, a post-processing weight value to a voice recognition result based on the call history information and correcting the voice recognition result,
- wherein the step of changing a value of a voice recognition parameter comprises:
- extracting at least one information of a number of total phonebook data pieces, a number of phonebook data pieces in which names are one word, or a number of phonebook data pieces in which names have similar pronunciations from the phonebook list,
- determining whether to change the value of the voice recognition parameter based on the extracted information, and
- changing the value of the voice recognition parameter according to a determination result.
