ElevenLabs API

The lil’bots platform comes with ElevenLabs access built in. You can use the ElevenLabs API to build bots that can generate human-like speech from text.

ElevenLabs provides provides the leading text-to-speech API for generating human-like speech from text. You can use the ElevenLabs API to generate speech from text, customize the voice, and more.

​

Using the ElevenLabs API

You can use the following endpoints in the ElevenLabs API:

• /v1/text-to-speech - generate speech from text docs
• /v1/voices - list the available voices docs

Currently, custom voices are not supported in the lil’bots platform. You can use the default voice for generating speech. You can see a list of available voices by making a request to the /v1/voices or by visiting the ElevenLabs API Reference.

Using the ElevenLabs API - JavaScript Runtime

Here’s a simple example of a bot that uses the ElevenLabs API to generate speech from text:

export async function main(inputs, params, accounts) {
	let text = inputs?.text ?? "Hello, World!"
	
	let fileName = `./speech.mp3`
	let response = await fetch(`https://api.elevenlabs.io/v1/text-to-speech/zBRstRiKO1kURcfe1n81?output_format=mp3_44100_128`, {
		method: 'POST',
		headers: {
			'Content-Type': 'application/json'
		},
		body: JSON.stringify({
			"text": text,
			"model": "eleven_turbo_v2"
		})
	})
	console.log(`Generation Response - ${response.status}`)
	if (response.status == 200 && response.body) {
		const f = await Deno.open(fileName, { create: true, write: true });
		await response.body.pipeTo(f.writable)
	} else {
		console.warn(await response.text())
	}

	return {
		title: "Generated Audio",
		file: fileName
	}
}
