Вот так можно, к примеру
<body>
<p>Название</p>
<audio src='audio/Dich.mp3' controls audioplay></audio>
<p>Название</p>
<audio src='audio/Flower.mp3' controls audioplay></audio>
<p>Название</p>
<audio src='audio/Dich.mp3' controls audioplay></audio>
<p>Название</p>
<audio src='audio/Flower.mp3' controls audioplay></audio>
<p>Название</p>
<audio src='audio/Dich.mp3' controls audioplay></audio>
<p>Название</p>
<audio src='audio/Flower.mp3' controls audioplay></audio>
<script>
const aud = document.querySelectorAll('audio')
Array.from(aud).map(el => el.addEventListener('play', () => {
const played = document.querySelector('[data-play="true"]')
if(played && played !== el) {
played.pause()
played.removeAttribute('data-play')
}
el.dataset.play = 'true'
}))
</script>
</body>
