Systems and methods for sender profile and/or recipient profile disambiguation and/or confirmation are disclosed. In instances where a sender profile is not indicated by a user sending a communication from a communal device, heuristic data may be utilized to infer the sender profile. Similar heuristic data may also be used when selection of the sender profile is associated with a low confidence level. Heuristic data may also be used to infer the recipient profile when the user does not indicate the recipient profile or when selection of the recipient profile is associated with a low confidence. Various confirmations may result from the sender and recipient profile disambiguation.

Enhanced capabilities within a telephone network are made accessible to a telecommunications device. The telecommunications device is used to dial a sequence. A network server receives and identifies the sequence invokes an advanced network function. A advanced network function server in communication with the network server provides instructions as to how the network server is to provide the advanced network function. The network server processes the call in accordance with the received instructions to provide the particular advanced network function.

Systems and methods for deriving contact information for a calling party analyze all or a portion of the audio of the telephone call to derive such contact. Likewise, all or a portion of a voice message left by a calling party could be analyzed to obtain contact information for the calling party.

During an electronic call between two individuals, a sound localization point simulates a location in empty space from where an origin of a voice of one individual occurs for the other individual.

A smartphone includes a camera that takes a picture of an ear of a user and retrieves at least one head-related transfer function (HRTF) from a database based on the picture. A digital signal processor (DSP) processes the sound to generate binaural sound, and a transmitter transmits the binaural sound to earphones or headphones worn on a head of the user.

Disclosed is a voice messaging and calling system for inmates and their friends and family (collectively referred to as outsiders). It extends existing inmate telephone systems (ITS) without requiring any additional installation within correctional facilities or modifications to the existing ITS. An existing ITS provides functional restrictions, security restrictions and privacy limitations. The described system enhances the existing ITS to reduce the functional restrictions by adding the ability to leave voicemail messages when outsiders are unavailable and return calls to, or leave messages for, multiple outsiders in a single call. An additional enhancement allows outsiders to leave messages for the inmate at any time, which the inmate can listen to later. The security restrictions and privacy limitations are unaffected and left in place. The described system also reduces costs for inmates by allowing them to leave messages for and return calls to, multiple outsiders in a single call.

A method provides a voice in binaural sound to a user. The method includes designating a sound localization point (SLP) with a handheld portable electronic device (HPED) and tracking the SLP with electronic glasses worn on a head of the user. A processor processes the voice with head-related transfer functions (HRTFs) to generate the voice in the binaural sound that localizes at the SLP at a location in empty space at physical object.

A method provides a voice in binaural sound to a user. A wearable electronic device (WED) selects head-related transfer functions (HRTFs) based on a distance between eyes of the user. A digital signal processor (DSP) in the WED processes the voice with the HRTFs to generate the voice in the binaural sound that localizes at a sound localization point (SLP) at a location in empty space to the user.

A method provides a voice in binaural sound to a first user during an electronic communication between the first user wearing a head mounted display (HMD) and a second user. The method includes designating a sound localization point (SLP) with a handheld portable electronic device (HPED), processing the voice of the second user with a digital signal processor (DSP) in the HMD, and moving the voice of the second user in response to a microphone in the HMD receiving a voice command from the first user.

Headphones provide binaural sound from a handheld portable electronic device (HPED) held in a hand of a user. The headphones include a head tracker and a digital signal processor (DSP) that processes sound from the HPED into binaural sound. The binaural sound localizes to multiple locations away from a head of the user while video plays on the HPED.
