Abstract

A computer detects a connected voice or video call between participants and records a brief media sample. Speech recognition is utilized to determine when the call is connected as well as to transcribe the content of the audio portion of the media sample. The recorded media sample and transcribed content is associated with the connected voice or video call such that a user may reference it at a later point. The computer additionally suggests creating or editing contact information associated with the participants of the connected voice or video call based on the transcribed content.

Claims

1. A method for generating call context metadata, the method comprising:

detecting that a call is connected, wherein the call is connected based on speech being detected;

recording a media sample corresponding to the connected call, wherein the media sample includes an audio recording of at least a portion of the detected speech;

identifying one or more words contained within the at least a portion of the detected speech, wherein identifying the one or more words further comprises;

identifying a first portion of the one or more words by comparing a voiceprint associated with the first portion with a voiceprint database and identifying a second portion of the one or more words by comparing a voiceprint associated with the second portion with the voiceprint database, and wherein the first portion of the one or more words corresponds to a first speaker and the second portion of the one or more words corresponds to a second speaker;

determining whether a phone number associated with the connected call is associated with one or more contacts detailed by a contact list of a user;

based on determining that the phone number associated with the connected call is not associated with the one or more contacts detailed by the contact list of the user, storing the recorded media sample and the identified one or more words in association with the connected call;

determining a location of the user based on analyzing Global Positioning System (GPS) information associated with a device of the user;

referencing a common name list, wherein the common name list details a set of commonly used names associated with a geographic area, and wherein the geographic area is an area within a distance of the location of the user;

determining whether at least one of the identified one or more words matches at least one of one or more names detailed by the common name list;

based on determining that at least one of the identified one or more words matches at least one of the one or more names detailed by the common name list, presenting an option to the user to add the at least one of the identified one or more words to the contact list of the user in association with the phone number associated with the connected call;

based on the user selecting the option to add the at least one of the identified one or more words to the contact list of the user in association with the phone number associated with the connected call, adding the at least one of the identified one or more words to the contact list of the user in association with the phone number associated with the connected call; and

deleting the recorded media sample and the identified one or more words stored in association with the connected call,

wherein one or more steps of the above method are performed using one or more computers.
