Systems and methods providing for secure voice print authentication over a network are disclosed herein. During an enrollment stage, a client's voice is recorded and characteristics of the recording are used to create and store a voice print. When an enrolled client seeks access to secure information over a network, a sample voice recording is created. The sample voice recording is compared to at least one voice print. If a match is found, the client is authenticated and granted access to secure information.Systems and methods providing for a dual use voice analysis system are disclosed herein. Speech recognition is achieved by comparing characteristics of words spoken by a speaker to one or more templates of human language words. Speaker identification is achieved by comparing characteristics of a speaker's speech to one or more templates, or voice prints. The system is adapted to increase or decrease matching constraints depending on whether speaker identification or speaker recognition is desired.

A system is disclosed that assists contact center agents with servicing customer enquiries. A wireless caller with an enquiry calls a contact center and is prompted to leave a voice message and accept a text callback as a response. The voice message is processed by a speech analytics system that extracts certain keywords in the voice message and develops a transcript as well. Upon selecting an available agent to provide the response, the keywords and transcript are presented to the agent along with a draft text response, formulated by the system using the identified keywords. Additional resources may be provided as necessary to the agent, who can also review the original audio recording. Upon reviewing and potentially editing the text response, the agent causes the text to be sent to the wireless caller, which may be sent as an SMS text, or in some other form.

Techniques for positioning participants of a conference call in a three dimensional (3D) audio space are described. Aspects of a system for positioning include a client component that extracts speech frames of a currently speaking participant of a conference call from a transmission signal.

A call center compliance system is used to ensure that agents adhere to call center policies and applicable regulations when handling calls. A call handler processing a call between an agent and a remote party bridges on a speech analytics component. A keyword set is used by the speech analytics component to analyze the remote party's or the agent's speech. If a keyword is detected, an event notification is provided from the speech analytics component to the call handler. A logic script executing in the call handler defines what actions are to occur in response to receiving the event notification. The call handler can provide information to the agent, record a violation, or await further event notifications. In one embodiment, detection of a first keyword in a first keyword set spoken by a remote party causes the agent's speech to be monitored using a second keyword set.

A method (196) for providing speech therapy to a learner (30) utilizes a formant estimation and visualization process (28) executable on a computing system (26). The method (196) calls for receiving a speech signal (35) from the learner (30) at an audio input (34) of the computing system (26) and estimating first and second formants (136, 138) of the speech signal (35). A target (94) is incorporated into a vowel chart (70) on a display (38) of the computing system (26). The target (70) characterizes an ideal pronunciation of the speech signal (35). A data element (134) of a relationship between the first and second formants (136, 138) is incorporated into the vowel chart (76) on the display (38). The data element (134) is compared with the target (70) to visualize an accuracy of the speech signal (35) relative to the ideal pronunciation of the speech signal (35).
