Text independent speaker recognition with simultaneous speech recognition for transparent command ambiguity resolution and continuous access control

A method of performing speaker recognition, comprising:

• simultaneously performing text-independent speaker recognition on a speech signal to simultaneously is identify a speaker;
• recognizing a command from said speech signal;
• interpreting said command based on said speaker identified in said text-independent speaker recognition step;
• retrieving enrolled information from a database corresponding to interpretation of said command in said interpreting step;
• and
• performing said command based on said enrolled information.

• retrieving enrolled information corresponding to said speaker identified in said text-independent speaker recognition step;
• and
• interpreting said command in accordance with said enrolled information retrieved corresponding to said speaker identified in said text-independent speaker recognition step.

A method of performing speaker recognition, comprising:

• performing text-independent speaker recognition on a speech signal to identify a speaker;
• simultaneously recognizing a command from said speech signal;
• interpreting said command based on said speaker identified in said text-independent speaker recognition step, said interpreting step in turn comprising the sub-steps of:
• determining if said recognized speaker is authorized to issue said command;
• and
• performing said command if said identified speaker is indeed authorized.

A method of performing speaker recognition in connection with access control, comprising:

• performing text-independent speaker recognition on a speech signal to identify a speaker;
• simultaneously recognizing a spoken utterance from said speech signal, said spoken utterance being uttered in connection with an access request;
• determining if said identified speaker is authorized to obtain access;
• and
• granting said access if said identified speaker is indeed authorized.

A method of performing speaker recognition, comprising:

• performing text-independent speaker recognition on a speech signal to identify a speaker;
• simultaneously recognizing a command from said speech signal;
• interpreting said command based on said speaker identified in said text-independent speaker recognition step, said interpreting step in turn comprising the sub-steps of:
• comparing said command with a list of authorized commands;
• and
• performing said command based on results obtained from said comparing step.

A method of performing speaker recognition, comprising:

• performing text-independent speaker recognition on a speech signal to identify a speaker;
• simultaneously recognizing a spoken utterance from said speech signal to obtain a recognized spoken utterance;
• and
• resolving ambiguity in said recognized spoken utterance based on said identity of said speaker identified in said text-independent speaker recognition step.

A method of performing speaker recognition, comprising:

• performing text-independent speaker recognition on a speech signal to identify a speaker, said performing in turn comprising identification of said speaker as a new user;
• recognizing a spoken utterance from said speech signal;
• and
• enrolling said new user in real time in response to said identification of said speaker as said new user.

A method of performing speaker recognition in connection with access control, comprising:

• performing text-independent speaker recognition on a speech signal to identify a speaker, said performing in turn comprising the sub-steps of:
• (a) sampling overlapping frames of said speech signal;
• (b) computing a feature vector for each said frame of said speech signal
• (c) comparing each said feature vector with vector parameters and variances stored in a plurality of codebooks corresponding to enrolled speakers;
• (d) accumulating a number of frames for which the corresponding feature vector corresponds to vector parameters and variances in said codebooks;
• and
• (e) identifying said speaker in response to results of at least one of said accumulating step and said comparing step;
• recognizing a spoken utterance from said speech signal, said spoken utterance being uttered in connection with an access request;
• determining if said identified speaker is authorized to obtain access;
• granting said access if said identified speaker is indeed authorized;
• and
• continuously verifying the recognition of said speaker in said identifying step as said speaker inputs additional speech signals.

An apparatus for speaker recognition in connection with access control, comprising:

• a speaker recognition processor which performs text-independent speaker recognition on a speech signal to identify a speaker, said speaker recognition processor being configured to determine if said identified speaker is authorized to obtain access;
• a speech recognizer which simultaneously recognizes a spoken utterance from said speech signal, said spoken utterance being uttered in connection with an access request;
• and
• a controller-interpreter which is configured to authorize granting of said access if said identified speaker is indeed authorized.

An apparatus for speaker recognition, comprising:

• a speaker recognition processor which performs text-independent speaker recognition on a speech signal to identify a speaker;
• a speech recognizer which simultaneously recognizes a spoken utterance from said speech signal to obtain a recognized spoken utterance;
• and
• a controller-interpreter which is configured to resolve ambiguity in said recognized spoken utterance based on said identity of said speaker identified by said speaker recognition processor.

An apparatus for speaker recognition, comprising:

• a speaker recognition processor which performs text-independent speaker recognition on a speech signal to identify a speaker, said speaker recognition processor being configured to identify said speaker as a new user;
• a speech recognizer which simultaneously recognizes a spoken utterance from said speech signal;
• and
• a controller-interpreter, which, together with said speaker recognition processor, is configured to enroll said new user in real time in response to said identification of said speaker as said new user.
