¿Hay alguna solución que lea en voz alta automáticamente al actualizar los soportes? Usé el código JS a continuación, pero no quiero tener que ejecutar a través de un botón

 var txtInput = document.querySelector('#txtInput'); var voiceList = document.querySelector('#voiceList'); var btnSpeak = document.querySelector('#btnSpeak'); var synth = window.speechSynthesis; var voices = []; PopulateVoices(); if(speechSynthesis !== undefined){ speechSynthesis.onvoiceschanged = PopulateVoices; } btnSpeak.addEventListener('click', ()=> { var toSpeak = new SpeechSynthesisUtterance(txtInput.value); var selectedVoiceName = voiceList.selectedOptions[0].getAttribute('data-name'); voices.forEach((voice)=>{ if(voice.name === selectedVoiceName){ toSpeak.voice = voice; } }); synth.speak(toSpeak); }); function PopulateVoices(){ voices = synth.getVoices(); var selectedIndex = voiceList.selectedIndex < 0 ? 0 : voiceList.selectedIndex; voiceList.innerHTML = ''; voices.forEach((voice)=>{ var listItem = document.createElement('option'); listItem.textContent = voice.name; listItem.setAttribute('data-lang', voice.lang); listItem.setAttribute('data-name', voice.name); voiceList.appendChild(listItem); }); voiceList.selectedIndex = selectedIndex; }
