Basic Usage

JavaScript

import { SixtyDBClient } from '60db';

const client = new SixtyDBClient('your-api-key');

const audio = await client.textToSpeech({
  text: 'Hello, world!',
  voice_id: 'default-voice',
  enhance: true,
  speed: 1.0
});

Python

from sixtydb import SixtyDBClient

client = SixtyDBClient('your-api-key')

audio = client.text_to_speech(
    text='Hello, world!',
    voice_id='default-voice',
    enhance=True,
    speed=1.0
)

with open('output.mp3', 'wb') as f:
    f.write(audio)

Voice Parameters

Speed

Control the speaking rate of the generated audio:

const audio = await client.textToSpeech({
  text: 'This will be spoken faster',
  speed: 1.5  // Range: 0.5 to 2.0
});

• 0.5: Half speed (slow)
• 1.0: Normal speed (default)
• 2.0: Double speed (fast)

Pitch

Adjust the pitch of the voice:

const audio = await client.textToSpeech({
  text: 'This will have a higher pitch',
  pitch: 1.3  // Range: 0.5 to 2.0
});

Enhancement

Enable audio enhancement for better quality:

const audio = await client.textToSpeech({
  text: 'Enhanced audio quality',
  enhance: true  // Default: true
});

Output Formats

Supported audio formats:

Format	Quality	File Size	Use Case
MP3	Good	Small	Web, mobile apps
WAV	Excellent	Large	Professional audio
OGG	Good	Small	Web streaming
FLAC	Lossless	Medium	High-quality archival

const audio = await client.textToSpeech({
  text: 'Hello, world!',
  output_format: 'wav'  // mp3, wav, ogg, flac
});

Best Practices

Text Formatting

• Use proper punctuation for natural pauses
• Break long texts into paragraphs
• Use SSML tags for advanced control (coming soon)

Voice Selection

• Test multiple voices for your use case
• Consider accent and gender for your audience
• Use custom voices for brand consistency

Performance

• Cache frequently used audio
• Batch requests when possible
• Use appropriate audio format for your use case

Quality

• Enable enhancement for production use
• Use WAV format for highest quality
• Test with different speed settings

Use Cases

Voice Assistants

// Voice assistant
async function speakResponse(text) {
  const audio = await client.textToSpeech({
    text: text,
    voice_id: 'assistant-voice',
    enhance: true
  });

  playAudio(audio);
}

Content Narration

// Generate audiobook chapter
const audio = await client.textToSpeech({
  text: chapterText,
  voice_id: 'narrator-voice',
  speed: 0.95,
  output_format: 'mp3'
});

saveToFile(`chapter-${chapterNum}.mp3`, audio);

Accessibility

// Make web content accessible
async function readAloud(element) {
  const text = element.textContent;
  const audio = await client.textToSpeech({
    text,
    voice_id: 'clear-voice',
    enhance: true
  });
  
  playAudio(audio);
}
