Saving random shapes to create picture of what I'm saying

Question

I would like to save the generated symbols so that it creates a picture. I used teachable machine sound to classify the certain symbols as sound. Also it generates almost 140 symbols for example triangles or circles per voice input - how can I reduce it, so that it only creates one or two per voice input?

let label = "Male dein eigenes Bild indem du Dreieck, Linie, Kreis oder Quadrat sagst.";
let classifier;
let modelURL = 'https://teachablemachine.withgoogle.com/models/3ThLR_ntF';

// STEP 1: Load the model!
function preload() {
  classifier = ml5.soundClassifier('https://teachablemachine.withgoogle.com/models/3ThLR_ntF/model.json');
}


function setup() {
  createCanvas(640, 520);
  classifyAudio();
  
  
}


// STEP 2 classify the videeo!
function classifyAudio() {
  classifier.classify(gotResults);
}

function draw() {
  background(255, 204, 0);

  // STEP 4: Draw the label
  textSize(18);
  textAlign(CENTER, CENTER);
  fill(0);
  text(label, width-320, height-35);
  
//Setting Symbols
  if (label == "Dreieck") {
    triangle(random(640),random(520), random(640),random(520),random(640),random(520));
  } 
  else if (label == "Linie") {
   line(random(640), random(520), random(640), random(520));
  } 
  else if (label == 'Kreis'){
   circle(random(640), random(520), random(300));
  }
  else if (label=='Quadrat'){
    quad(x1=random(640), y1=random(520),x2=(x1+random(50,200)),y2=(y1),x3=(x2),y3=(y2+random(50,200)),x4=(x1), y4=(y3))
  }
  
  // Draw the symbols
  textSize(256);
  
  
}

// STEP 3: Get the classification!
function gotResults(error, results) {
  // Something went wrong!
  if (error) {
    console.error(error);
    return;
  }
  // Store the label and classify again!
  label = results[0].label;
}

In draw the symbols I thought I could save the symbols but its not working also not with print. How can I save the symbols on the canva so that it looks like a piture created with the symbols. And how can I reduce the generated symbols? Please help thank you!
