User interface for secure access to a device using speaker verification

A device comprising:

• a memory configured to store a speaker model;
• a receiver configured to receive an input audio signal associated with sound in a sector or in multiple sectors of a region proximate to the receiver, the sound associated with at least one phrase;
• a processor configured to:
• determine a first confidence level associated with a first portion of the input audio signal based on the speaker model, the first portion of the input audio signal corresponding to a first portion of the at least one phrase;
• update the speaker model based on the first portion of the input audio signal;
• and
• determine a second confidence level associated with a second portion of the input audio signal based on the speaker model, the second portion of the input audio signal corresponding to a second portion of the at least one phrase;
• and
• a display configured to present a graphical user interface based on analysis performed at the processor, the graphical user interface associated with the first confidence level or associated with the second confidence level and including information associated with a histogram, the histogram configured to indicate, for each sector of the multiple sectors, a detection of sounds or of directional sources of sounds associated with the sector.
