Speechify

Speechify offer a text-to-speech API that delivers their most natural and beloved AI voices directly to developers worldwide.

Setup

The Speechify provider is available by default in Orate. To import it, you can use the following code:

import { speechify } from 'orate/speechify';

Configuration

The Speechify provider looks for the SPEECHIFY_API_KEY environment variable. This variable is required for the provider to work. Simply add the following to your .env file:

SPEECHIFY_API_KEY="your_api_key"

Usage

The Speechify provider provides a single interface for all of Speechify's speech services.

Text to Speech

The Speechify provider provides a tts function that allows you to create a text-to-speech synthesis function using Speechify's TTS. By default, the tts function uses the simba-multilingual model and the george voice.

import { speak } from 'orate';
import { speechify } from 'orate/speechify';
 
const speech = await speak({
  model: speechify.tts(),
  prompt: 'Hello, world!',
});

You can specify the model and voice to use by passing them as arguments to the tts function.

const speech = await speak({
  model: speechify.tts('simba-turbo', 'kristy'),
  prompt: 'Hello, world!',
});

You can also specify specific Speechify properties by passing them as an argument to the tts function.

const speech = await speak({
  model: speechify.tts('simba-turbo', 'kristy', {
    options: {
      enableLoudnessNormalization: true,
    }
  }),
  prompt: 'Hello, world!',
});
