Unleashing Potential: Unreal Speech API Quickstarts

Python Integration: Streamlining Your TTS Projects

For developers looking to streamline their TTS projects with Python, the Unreal Speech API presents a straightforward way to integrate advanced text-to-speech capabilities. The API's /stream endpoint offers a rapid and synchronous response, streaming back raw audio data for texts of up to 1,000 characters. Below is an example of how to leverage the requests library in Python to interact with the Unreal Speech API:

import requests

response = requests.post(
  'https://api.v6.unrealspeech.com/synthesisTasks',
  headers = {
    'Authorization' : 'Bearer YOUR_API_KEY'
  },
  json = {
    'Text': '''<YOUR_TEXT>''', # Up to 500,000 characters
    'VoiceId': '<VOICE_ID>', # Scarlett, Dan, Liv, Will, Amy
    'Bitrate': '192k', # 320k, 256k, 192k, ...
    'Speed': '0', # -1.0 to 1.0
    'Pitch': '1', # 0.5 to 1.5
    'TimestampType': 'sentence', # word or sentence
   #'CallbackUrl': '<URL>', # pinged when ready
  }
)

Node.js and React Native: Cross-Platform Voice Solutions

Developing TTS applications for multiple platforms is made simple with Node.js and React Native using the Unreal Speech API. The /stream endpoint’s compatibility with JavaScript allows developers to implement TTS functionality effectively. Here's a Node.js example using the axios library to send a POST request to Unreal Speech API:

const axios = require('axios');

const headers = {
    'Authorization': 'Bearer YOUR_API_KEY',
};

const data = {
    'Text': '<YOUR_TEXT>', // Up to 500,000 characters
    'VoiceId': '<VOICE_ID>', // Scarlett, Dan, Liv, Will, Amy
    'Bitrate': '192k', // 320k, 256k, 192k, ...
    'Speed': '0', // -1.0 to 1.0
    'Pitch': '1', // 0.5 to 1.5
    'TimestampType': 'sentence', // word or sentence
  //'CallbackUrl': '<URL>', // pinged when ready
};

axios({
    method: 'post',
    url: 'https://api.v6.unrealspeech.com/synthesisTasks',
    headers: headers,
    data: data,
}).then(function (response) {
    console.log(JSON.stringify(response.data));
});
