Intel MKL-DNN による音声コマンド認識コードの生成

この例では次を使用します。

この例では、音声コマンド認識のための特徴抽出と畳み込みニューラルネットワーク (CNN) を Intel® プロセッサで展開する方法を説明します。特徴抽出とネットワークコードを生成するために、MATLAB® Coder™ と Intel® Math Kernel Library for Deep Neural Networks (MKL-DNN) を使用します。この例では、生成されたコードは MATLAB 実行可能ファイル (MEX) 関数であり、予測された音声コマンドと時間領域信号および聴覚スペクトログラムを表示する MATLAB スクリプトによって呼び出されます。オーディオの前処理およびネットワーク学習の詳細については、Train Speech Command Recognition Model Using Deep Learning (Audio Toolbox)を参照してください。

サポートされるライブラリのバージョン、および環境変数の設定の詳細については、MATLAB Coder を使用した深層学習の前提条件 (MATLAB Coder)を参照してください。

MATLAB でのストリーミングのデモ

特徴抽出パイプラインおよび分類に関して、Train Speech Command Recognition Model Using Deep Learning (Audio Toolbox)で構築したのと同じパラメーターを使用します。

ネットワークに学習させたのと同じサンプルレート (16 kHz) を定義します。分類レートと、フレームごとに入力されるオーディオサンプルの数を定義します。ネットワークに入力される特徴は、オーディオデータ 1 秒に対応するバークスペクトログラムです。バークスペクトログラムは、10 ms のホップをもつ 25 ms のウィンドウについて計算されます。

fs = 16000; 
classificationRate = 20;
samplesPerCapture = fs/classificationRate;

segmentDuration = 1;
segmentSamples = round(segmentDuration*fs);

frameDuration = 0.025;
frameSamples = round(frameDuration*fs);

hopDuration = 0.010;
hopSamples = round(hopDuration*fs);

audioFeatureExtractor (Audio Toolbox)オブジェクトを作成し、ウィンドウを正規化せずに帯域数 50 のバークスペクトログラムを抽出します。

afe = audioFeatureExtractor( ...
    'SampleRate',fs, ...
    'FFTLength',512, ...
    'Window',hann(frameSamples,'periodic'), ...
    'OverlapLength',frameSamples - hopSamples, ...
    'barkSpectrum',true);

numBands = 50;
setExtractorParameters(afe,'barkSpectrum','NumBands',numBands,'WindowNormalization',false);

事前学習済みの畳み込みニューラルネットワークとラベルを読み込みます。

load('commandNet.mat')
labels = trainedNet.Layers(end).Classes;
numLabels = numel(labels);
backgroundIdx = find(labels == 'background');

バッファーおよび判定しきい値を定義し、ネットワーク予測を後処理します。

probBuffer = single(zeros([numLabels,classificationRate/2]));
YBuffer = single(numLabels * ones(1, classificationRate/2)); 

countThreshold = ceil(classificationRate*0.2);
probThreshold = single(0.7);

audioDeviceReader (Audio Toolbox)オブジェクトを作成し、デバイスからオーディオを読み取ります。dsp.AsyncBuffer (DSP System Toolbox)オブジェクトを作成し、オーディオをチャンクにバッファリングします。

adr = audioDeviceReader('SampleRate',fs,'SamplesPerFrame',samplesPerCapture,'OutputDataType','single');
audioBuffer = dsp.AsyncBuffer(fs);

dsp.MatrixViewer (DSP System Toolbox)オブジェクトおよびtimescope (DSP System Toolbox)オブジェクトを作成し、結果を表示します。

matrixViewer = dsp.MatrixViewer("ColorBarLabel","Power per band (dB/Band)", ...
    "XLabel","Frames", ...
    "YLabel","Bark Bands", ...
    "Position",[400 100 600 250], ...
    "ColorLimits",[-4 2.6445], ...
    "AxisOrigin",'Lower left corner', ...
    "Name","Speech Command Recognition Using Deep Learning");

timeScope = timescope('SampleRate', fs, ...
    'YLimits',[-1 1], 'Position', [400 380 600 250], ...
    'Name','Speech Command Recognition Using Deep Learning', ...
    'TimeSpanSource','Property', ...
    'TimeSpan',1, ...
    'BufferLength',fs);

timeScope.YLabel = 'Amplitude';
timeScope.ShowGrid = true;

時間スコープおよび行列ビューアーを表示します。時間スコープおよび行列ビューアーの両方が開いているか、制限時間に達するまで、コマンドを検出します。制限時間に達する前にライブ検出を停止するには、時間スコープウィンドウまたは行列ビューアーウィンドウを閉じます。

show(timeScope)
show(matrixViewer)
timeLimit = 10;

tic
while isVisible(timeScope) && isVisible(matrixViewer) && toc < timeLimit
    %% Capture Audio
    x = adr();
    write(audioBuffer,x);
    y = read(audioBuffer,fs,fs-samplesPerCapture);
    
    % Compute auditory features
    features = extract(afe,y);
    auditory_features = log10(features + 1e-6);
    
    % Transpose to get the auditory spectrum
    auditorySpectrum = auditory_features';
    
    % Perform prediction
    probs = predict(trainedNet, auditory_features);      
    [~, YPredicted] = max(probs);
    
    % Perform statistical post processing
    YBuffer = [YBuffer(2:end),YPredicted];
    probBuffer = [probBuffer(:,2:end),probs(:)];

    [YMode_idx, count] = mode(YBuffer);
    count = single(count);
    maxProb = max(probBuffer(YMode_idx,:));

    if (YMode_idx == single(backgroundIdx) || count < countThreshold || maxProb < probThreshold)
        speechCommandIdx = backgroundIdx;
    else
        speechCommandIdx = YMode_idx;
    end
    
    % Update plots
    matrixViewer(auditorySpectrum);
    timeScope(x);

    if (speechCommandIdx == backgroundIdx)
        timeScope.Title = ' ';
    else
        timeScope.Title = char(labels(speechCommandIdx));
    end
    drawnow
end

スコープを非表示にします。

MATLAB コードの展開準備

コード生成と互換性がある特徴抽出を実行する関数を作成するには、audioFeatureExtractor オブジェクトでgenerateMATLABFunction (Audio Toolbox)を呼び出します。オブジェクト関数 generateMATLABFunction は、コード生成と互換性があり、同等の特徴抽出を実行するスタンドアロン関数を作成します。

generateMATLABFunction(afe,'extractSpeechFeatures')

サポート関数 HelperSpeechCommandRecognition は、以前に説明した特徴抽出およびネットワーク予測プロセスをカプセル化します。特徴抽出はコード生成と互換性があるため、特徴抽出は生成された関数 extractSpeechFeatures によって処理されます。ネットワークはコード生成と互換性があるため、サポート関数は関数coder.loadDeepLearningNetwork (MATLAB Coder)を使用してネットワークを読み込みます。

関数 HelperSpeechCommandRecognition を使用し、音声コマンドのライブ検出を実行します。

show(timeScope)
show(matrixViewer)
timeLimit = 10;

tic
while isVisible(timeScope) && isVisible(matrixViewer) && toc < timeLimit
    x = adr();    
        
    [speechCommandIdx, auditorySpectrum] = HelperSpeechCommandRecognition(x);  
		
    matrixViewer(auditorySpectrum);
    timeScope(x);
   
    if (speechCommandIdx == backgroundIdx)
        timeScope.Title = ' ';
    else
        timeScope.Title = char(labels(speechCommandIdx));
    end
    drawnow
end

スコープを非表示にします。

MATLAB 実行可能ファイルの生成

実行可能プログラムの生成用にコード生成構成オブジェクトを作成します。ターゲット言語を C++ に指定します。

cfg = coder.config('mex');
cfg.TargetLang = 'C++';

MKL-DNN ライブラリで深層学習コード生成用の構成オブジェクトを作成します。コード生成構成オブジェクトに構成オブジェクトを追加します。

dlcfg = coder.DeepLearningConfig('mkldnn');
cfg.DeepLearningConfig = dlcfg;

codegen (MATLAB Coder)を呼び出し、関数 HelperSpeechCommandRecognition 用の C++ コードを生成します。構成オブジェクトとプロトタイプの引数を指定します。HelperSpeechCommandRecognition_mex という名前の MEX ファイルが現在のフォルダーに生成されます。

codegen HelperSpeechCommandRecognition -config cfg -args {rand(samplesPerCapture, 1, 'single')} -profile -report -v

MEX 実行時間の評価

tic および toc を使用し、MATLAB でシミュレーションを完全に実行するための実行時間と、MEX 関数の実行時間を比較します。

シミュレーションコードのパフォーマンスを測定します。

testDur = 50e-3;
x = pinknoise(fs*testDur,'single');
numLoops = 100;
tic
for k = 1:numLoops
    [speechCommandIdx, auditory_features] = HelperSpeechCommandRecognition(x);
end
exeTime = toc;
fprintf('SIM execution time per 50 ms of audio = %0.4f ms\n',(exeTime/numLoops)*1000);

SIM execution time per 50 ms of audio = 6.8212 ms

MEX コードのパフォーマンスを測定します。

tic
for k = 1:numLoops
    [speechCommandIdx, auditory_features] = HelperSpeechCommandRecognition_mex(x);
end
exeTimeMex = toc;
fprintf('MEX execution time per 50 ms of audio = %0.4f ms\n',(exeTimeMex/numLoops)*1000);

MEX execution time per 50 ms of audio = 1.3347 ms

MEX 関数を使用し、得られるパフォーマンスを評価します。このパフォーマンステストは、NVIDIA Quadro P620 (Version 26) GPU と、3.60 GHz で動作する Intel(R) Xeon(R) W-2133 CPU を使用するマシン上で実行されます。

PerformanceGain = exeTime/exeTimeMex

PerformanceGain = 5.1107
