In this code I want to register names not numbers in the database so that when I test it it will detect who the voice is that. anyone can help me what should I write in the code. Thank you

Also please help me in the testing part of when I record my voice it will recognized it and file my similar audio in the database and it will say access granted or access denied if it doesnt match. Please help me revise my code. @Walter Roberson here is the below is the code.

clear all
close all
clc
%% Creating a recorder object
recorder = audiorecorder(16000, 8, 1); % 16000 Hz, 8 bits, 1 channels
%% Record the user's voice for 5s
disp("Please say something.")
drawnow(); % update figures and process callbacks
pause(1) % pauses for 1s
recordblocking(recorder, 7); % records the audio to recorder object for 5s.
disp('Recorded')
%% Play the user's voice
play(recorder); % plays the audio from the recorder object
data = getaudiodata(recorder); % data is stored in a 8000 x 2 matrix.
% plot(data); % plots the data
% xlabel("Frequency") 
% ylabel("Normalized values between -1 to 1")
% title("Audio sample")
%% Feature Extraction
f_test = voiceFeatures(data)
%% Find the closest feature from database.
load database
D = [];
for i = 1:size(F, 1)
    distance = abs(F(i) - f_test); % calculates the distance between the stored value in the database and the test value.
    D = [D distance]; % adds the distance d to the vector D.
end
%% Smallest distance
smallest_distance = inf; % initially, we take the smallest distance to be infinity.
index = 0; % initially, we take the index to be 0
for i = 1:length(D)
    if D(i) < smallest_distance % if the current distance is smaller than the smallest distance.
        smallest_distance = D(i); % then replace the smallest distance with the current distance.
        index = i; % change the index to the current distance's index.
    end
end
detected_class = C(index);
disp('The detected class is ');
detected_class

is this correct?

in this code I want to use names not numbers in detecting I have training. and this testing part is a continuation. how can I detect the name of the users voice? @Walter Roberson

Walter Roberson 2022-12-9

You cannot do that. There is no code in the world that can take recorded speech data and directly convert it into the name of the speaker, without going through a numeric step of analyzing coefficients and comparing against recorded coefficients to determine closest match.

As such, code is always going to arrive at an index of which match or matches are closest, and you would then always use that index to look into the list of names to pull out the name associated with the match.

It sounds like you might be able to use a dictionary
