Abstract:
1. A method for associating a voice of a first human speaker with at least one of a multiplicity of speakers, each of the multiplicity of speakers associated with an acoustic model and with data, the method comprising the steps of: capturing an audio signal of the first human speaker communicating with a second human speaker and extracting the voice of the first human speaker; receiving or extracting the data associated with each of the multiplicity of speakers; generating tags associated with each of the acoustic models of the multiplicity of speakers; wherein the tags represent an at least one parameter associated with the acoustic model of the speaker and with at least one parameter associated with the acoustic models of persons who are known to be connected directly or indirectly via one or more middle persons to a known speaker in the interaction; constructing one or more groups comprising acoustic models of speakers based on tag value similarity; determining an order for the groups by giving high priority to groups with persons who have direct connection with the first speaker or the second speaker and lower priority to groups with persons having indirect connection to the first speaker or the second speaker; selecting at least one group to be matched against the voice of the first speaker; determining an at least one non-acoustic score between data related to the first speaker, and the tags of the at least one matched group or the tags of an at least one acoustic model from the at least one matched group; determining an at least one acoustic score between the voice of the first speaker and an at least one acoustic model from the at least one matched group; obtaining a total score by combining the non-acoustic score with the acoustic score; determining according to the total score whether an identification criteria was met; and if the identification criteria was met, associating the first speaker with the at least one model from the matched group.
