Yes, it's possible to get and play the mp3 of the AI voices of play.ht! Just in your browser, just client-side. You can open up developer console and copy paste the code.
You have to replace SECRETKEY and USERID below with your own ones. You log in and find them here: https://play.ht/app/api-access
or via menu: Accessibility -> Integrations -> API Access
async function speak(text) {
return new Promise(async (resolve, reject) => {
try {
const response = await (await fetch('https://play.ht/api/v1/convert', {
method: 'POST',
headers: {
'Authorization': 'SECRETKEY',
'X-User-ID': 'USERID',
'Content-Type': 'application/json'
},
body: JSON.stringify({
"voice": "en-US-MichelleNeural",
"content": text.split(/\.|\?|!/),
"title": "Testing Italian api convertion"
})
})).json();
const mp3Url = `
https://media.play.ht/full_${response.transcriptionId}.mp3`;
console.log(mp3Url);
while(true) {
console.log(`trying again...`);
if((await fetch(mp3Url)).status === 200) {
snd = new Audio(mp3Url);
snd.play();
snd.onended = resolve;
break;
}
}
} catch (err) {
reject(err);
}
});
}
Finding the right mp3 url
I discovered the mp3 URL "https://media.play.ht/full_${response.transcriptionId}.mp3" by logging into the play.ht website, navigating to the 'files' section in the menu on the left, and playing the audio fragments. This URL was not included in the play.ht documentation. I also noted that the URL provided in the documentation for fetching the mp3 file, "./articleStatus?transcriptionId={transcriptionId}", did not work and returned a "Forbidden" error.
A loop until the mp3 is available
The mp3 is not immediately available, so I made a while-loop to try again and again!
Promise
The function is a promise, so that you can also await it. This can be useful in applications, so that you know when the text has been spoken
Voice
You can change the voice from a list here. In the script above just replace en-US-MichelleNeural with the voice name.
