Speechify Text to Speech API SDK Everything you need to get started with the Speechify text to speech API SDK.

Get Started with The Speechify Text to Speech SDK

The Speechify Text to Speech API SDK allows developers to integrate high-quality, natural-sounding text-to-speech (TTS) capabilities into applications with minimal effort. It offers a streamlined way to convert text into audio on both server and client-side environments.

Try the PlayHT text to speech API for free. With a much lower latency than Speechify, and much higher voice quality, PlayHT is perfect for streaming or anything your business demands.

1. What You Need to Get Started

To use the Speechify SDK, you’ll need:

• Node.js installed on your system.
• Speechify API credentials, available by signing up for an API key on the Speechify developer portal.
• A server or web client where you want to integrate TTS features.

2. Installation

Install the Speechify API SDK via npm:

npm install @speechify/api-sdk

This package provides tools for interacting with the Speechify API.

3. How to Get Started

Authentication

Before making any requests, authenticate using the API key:

const Speechify = require('@speechify/api-sdk');

// Initialize the SDK with your API key
const speechify = new Speechify({
  apiKey: 'YOUR_API_KEY',
});

Generate Speech from Text

Once authenticated, you can easily generate speech from text. Here’s a simple example:

async function textToSpeech() {
  const result = await speechify.createAudio({
    text: 'Hello, world!',
    voice: 'en_us_male',  // Specify voice preference
    format: 'mp3',        // Output format
  });

  console.log('Audio URL:', result.audioUrl);  // URL to download or play the audio
}

textToSpeech();

This code converts the text “Hello, world!” into an MP3 audio file using the selected voice.

4. Error Handling

Handling potential issues ensures a smooth user experience. Example error handling:

try {
  await speechify.createAudio({
    text: '',
    voice: 'en_us_female',
  });
} catch (error) {
  console.error('Error generating audio:', error.message);
}

This ensures graceful failures if, for example, no text is provided or the API limit is reached.

5. Advanced Features and Considerations

Token Management

The SDK automatically handles authentication token renewal, which simplifies long-running processes that require continuous interaction with the API.

Rate Limits

Keep in mind that Speechify API might have rate limits depending on your plan. It’s a good idea to cache or batch your requests when dealing with high volumes of text.

Frontend vs Backend Usage

• Frontend: Ideal for apps that require immediate voice generation based on user input. However, ensure secure handling of API keys.
• Backend: Best suited for pre-generating audio for content delivery systems or bulk operations.

6. Performance Tips

• Batch Requests: Instead of making multiple individual requests, batch your text inputs to minimize API calls.
• File Caching: Cache frequently used audio files to reduce redundant API usage and save bandwidth.

By integrating the Speechify API SDK, you can enhance your application with seamless text-to-speech conversion, offering users an auditory alternative to textual content. For more detailed API reference, visit the official documentation.
