In the frequency domain, the phase of the audio signal is manipulated by the phase of a reference phase sequence, followed by transform into time domain. Because a change of the audio signal phase over the whole frequency range can be audible, the phase manipulation is carried out with a maximum amount only within one or more small frequency ranges which are located in the higher frequencies and/or in noisy audio signal sections, according to psycho-acoustic principles. Preferably, the allowable amplitude of the phase changes in the remaining frequency ranges is controlled according to psycho-acoustic principles.

| 20150066512 | Method and Apparatus for Detecting Synthesized Speech - Computer systems employing speaker verification as a security approach to prevent un-authorized access by intruders may be tricked by a synthetic speech with voice characteristics similar to those of an authorized user of the computer system. According to at least one example embodiment, a method and corresponding apparatus for detecting a synthetic speech signal include extracting a plurality of speech features from multiple segments of the speech signal; analyzing the plurality of speech features to determine whether the plurality of speech features exhibit periodic variation behavior; and determining whether the speech signal is a synthetic speech signal or a natural speech signal based on whether or not a periodic variation behavior of the plurality of speech features is detected. The embodiments of synthetic speech detection result in security enhancement of the computer system employing speaker verification. | 03-05-2015 |
| 20150073807 | SYSTEM AND METOD FOR VOICE AUTHENTICATION OVER A COMPUTER NETWORK - Systems, computer-implemented methods, and tangible computer-readable media are provided for voice authentication. The method includes receiving a speech sample from a user through an Internet browser for authentication as part of a request for a restricted-access resource, transmitting an authentication request to an authentication server, which compares the speech sample to a previously established speech profile associated with the user, receiving a response from the authentication server, and providing access to the restricted access resource based on the response. | 03-12-2015 |
| 20150302856 | METHOD AND APPARATUS FOR PERFORMING FUNCTION BY SPEECH INPUT - A method for performing a function in an electronic device is disclosed. The method may include receiving an input sound stream including a speech command indicative of the function and identifying the function from the speech command in the input sound stream. Further, the method may determine a security level associated with the speech command. It may be verified whether the input sound stream is indicative of a user authorized to perform the function based on the security level. In response to verifying that the input sound stream is indicative of the user, the function may be performed. | 10-22-2015 |
| 20160125884 | Utilizing Voice Biometrics - Methods, systems, computer-readable media, and apparatuses for utilizing voice biometrics to prevent unauthorized access are presented. In some embodiments, a computing device may receive a voice sample. Subsequently, the computing device may determine a voice biometric confidence score based on the voice sample. The computing device then may evaluate the voice biometric confidence score in combination with one or more other factors to identify an attempt to access an account without authorization. | 05-05-2016 |
| 20160148453 | VEHICLE ELECTRONIC KEY SYSTEM - A vehicle electronic key system for unlocking a vehicle includes an electronic key and a vehicle controlling device. The electronic key includes a first controller, a signal transmitting module configured to collet and transmit speech signals, and a wireless charging receiving coil configured to transmit electromagnetic signals to the first controller. The vehicle controlling device includes a second controller configured to authenticate the speech signals and unlock the vehicle, a signal receiving module configured to receive speech signals sent by the signal transmitting module and send the speech signals to the second controller, and a wireless charging transmitting coil configured to transmit the electromagnetic signals to the wireless charging receiving coil. The second controller is further configured to drive the wireless charging transmitting coil. The first controller is configured to convert the electromagnetic signals to electric energy and send the electric energy to the signal transmitting module. | 05-26-2016 |
