A method and a system for voice transmission control. The method comprises: receiving, by a voice answering device, a voice command and transmitting the voice command to a sound control server through a network data transmission channel; recognizing, by the sound control server, the voice command, generating corresponding second VXML control information based on a recognition result, and transmitting the second VXML control information to the voice answering device through the network data transmission channel; and performing, by the voice answering device, an operation according to the received second VXML control information. With this method, the architecture and workflow of the communication system can be simplified, and the difficulty of design thereof can be reduced.

A method for speaker recognition comprising: obtaining speaker information for a target speaker; obtaining speech samples from telephone calls from an unknown speaker; classifying the speech samples according the unknown speaker thereby providing speaker-dependent classes of speech samples; extracting speaker information of each of the speaker-dependent classes of speech samples; combining the extracted speaker information; comparing the combined extracted speaker information with the stored speaker information for the target speaker to obtain a comparison result; and determining whether the unknown speaker is identical with the target speaker based on the comparison result.

The present disclosure discloses a method for identifying an identity, device and a communication terminal. The method includes that: a voiceprint feature of a current call object and a mobile phone number of the current call object are extracted; the identity of the current call object is identified according to the voiceprint feature and the mobile phone number. The present disclosure solves the problem in the related art that it is difficult to effectively identify the identity of a call object, thus providing a method for effectively identifying the identity of a current call object and technically reducing the probability of phone fraud on a user.

This disclosure describes techniques and systems for encoding instructions in audio data that, when output on a speaker of a first device in an environment, cause a second device to output content in the environment. In some instances, the audio data has a frequency that is inaudible to users in the environment. Thus, the first device is able to cause the second device to output the content without users in the environment hearing the instructions. In some instances, the first device also outputs content, and the content output by the second device is played at an offset relative to a position of the content output by the first device.

The method comprises: receiving, by a voice answering device, a voice command and transmitting the voice command to a sound control server through a network data transmission channel; recognizing, by the sound control server, the voice command, generating corresponding VXML control information based on a recognition result, and transmitting the VXML control information to the voice answering device through the network data transmission channel; and performing, by the voice answering device, an operation according to the received VXML control information. With this method, the architecture and workflow of the communication system can be simplified, and the difficulty of design thereof can be reduced.

Methods, systems, and devices for cross-linking events and persons using anonymized voice fingerprint identifiers (IDs) and call metadata are described. The method can include retrieving, form a centralized database, call metadata associated with a caller index ID. The method can include determining call metadata characteristics for the call metadata. The method can include matching the call metadata characteristics of the call metadata with characteristics associated with a personality type of a psychological behavioral model. The method can include generating a caller profile that comprises personality type information for the personality type. The method can include associating the caller profile with the caller index ID. The method can include storing the caller profile in an entry in the centralized database associated with the caller index ID.

A caller identification apparatus, in order to make, with higher precision, a sharp distinction between a call from a fraud and a call from a person who is not a fraud, comprises a storage means and a voice characteristic analysis means. The storage means stores both a white list with which first voice characteristic information, which is the voice characteristic information of closely related persons of a call recipient, is registered and a black list with which second voice characteristic information, which is the voice characteristic information of frauds, is registered. The voice characteristic analysis means acquires the voice data of a call, obtains third voice characteristic information, which is the voice characteristic information of the voice data, and determines whether the third voice characteristic information matches the first voice characteristic information or the second voice characteristic information. If the third voice characteristic information matches neither the first voice characteristic information nor the second voice characteristic information, the voice characteristic analysis means determines whether the third voice characteristic information includes the voice characteristic information of any multiple persons. If the third voice characteristic information includes the voice characteristic information of any multiple persons, the voice characteristic analysis means obtains a first determination result that the call is probably a call from said frauds.

A facility and method for analyzing and classifying calls without transcription via keyword spotting is disclosed. The facility uses a group of calls having known outcomes to generate one or more domain- or entity-specific grammars containing keywords and related information that are indicative of particular outcome. The facility monitors telephone calls by determining the domain or entity associated with the call, loading the appropriate grammar or grammars associated with the determined domain or entity, and tracking keywords contained in the loaded grammar or grammars that are spoken during the monitored call, along with additional information. The facility performs a statistical analysis on the tracked keywords and additional information to determine a classification for the monitored telephone call.
