摘要:
An electronic device is provided. The electronic device includes a microphone configured to receive a voice, communication circuitry configured to communicate with an external electronic device, a memory, and a processor operatively connected to the microphone, the communication circuitry, and the memory. The memory stores instructions that, when executed by the processor, cause the electronic device to perform voice recognition for voice data corresponding to the voice, and determine whether to perform voiceprint recognition for the voice data based on whether a first expression is included in a result of the voice recognition.

An information processing apparatus that detects a voice command via a microphone in order to activate the device and execute certain applications. The apparatus comprises a digital signal processor (DSP) and a host controller which are responsible for processing the voice commands. The DSP recognizes and processes voice commands intermittently while the host processor is in a sleep state, thereby reducing the overall power consumption of the apparatus. Further, when the DSP is configured to recognize voice commands intended only to activate the device, a memory having a sufficiently lower storage capacity suffices.

Caller identity verification can be improved by employing a multi-step verification that leverages speech features (28, 30) that are obtained from multiple interactions with a caller. An enrollment is performed in which customer speech features (23) and customer information are collected. When a caller calls into the call center (11), an attempt is made to verify the caller's identity by requesting the caller to speak a predefined phrase, extracting speech features from the spoken phrase, and comparing the phrase. If the purported identity (14) of the caller can be matched with one of the customers based on the comparison, the identity of the caller is verified. If the match cannot be made with a high enough degree of confidence, the customer is asked to speak any phrase that is not predefined. Features (30) are extracted from the caller's speech, combined with features (28) previously extracted from the predefined speech, and compared to the enrollment features (23).

Provided are a method and apparatus for managing a graded cipher. The method includes that: a corresponding relationship between different security grades and corresponding voice passwords is established, herein the voice password corresponding to each security grade in the corresponding relationship is a part or all of a preset voice password; and a voice password is received from a user, and the obtained corresponding relationship is searched for the security grade corresponding to the voice password matched with the received voice password.

A method for secure speaker verification, the method comprising the steps of: generating (501) a random, textual prompt for a user to speak; awaiting (502) for a user to speak the generated, textual prompt and recording the corresponding speech; in parallel to said speech recording (502), recording (503) ultrasound signals reflected from the user's face; subjecting (504) the recorded speech to automatic speech recognition in order to obtain a textual representation of the speech; detecting (505) user's liveness based on a correspondence of said recorded audio signal with said recorded ultrasound signal as well as based on the automatically recognized speech; executing (506) a text accuracy validation on said recorded speech subjected to the automatic speech recognition in comparison to the generated, textual prompt; and executing an authentication (507) of the user based on results of said detecting (505) user's liveness, and said text accuracy validation in order to verify whether the user was speaking the generated prompt, at the time of recording.

The present disclosure relates to a method of performing speech recognition on board of an aircraft, to a computer program for executing the method, as well as to a speech recognition unit for performing speech recognition on board of an aircraft. The method comprises: receiving (S202) a speech signal spoken by a user; performing speaker recognition (S204) on the speech signal to identify the user from the speech signal; selecting (S206) a speech recognition user profile which is associated with the identified user; and performing speech recognition (S208) on the speech signal using the selected user profile.
摘要:
The present invention refers to a method for verifying the identity of a speaker based on the speakers voice comprising the steps of: a) receiving a voice utterance; b) using biometric voice data to verify (10) that the speakers voice corresponds to the speaker the identity of which is to be verified based on the received voice utterance; and c) verifying (12, 13) that the received voice utterance is not falsified, preferably after having verified the speakers voice; d) accepting (16) the speakers identity to be verified in case that both verification steps give a positive result and not accepting (15) the speakers identity to be verified if any of the verification steps give a negative result. The invention further refers to a corresponding computer readable medium and a computer.
摘要:
A terminal comprises: speech receiving means that receives speech in a locked state; voiceprint authentication means that performs voiceprint authentication based on the speech received in the locked state and determining whether or not a user is legitimate; speech recognition means that performs speech recognition of the speech received in the locked state; and execution means that executes an application using a result of the speech recognition. It is possible to easily unlock the terminal having the voiceprint authentication and speech recognition functions.
