Prerequisites

All you need is:
  • Free trial API key: dd-00000000000000000000000065c9cbfe
  • A voice preset — see Voice Presets for the full list

​
Generate speech with the Python SDK

1

Install the SDK

pip install deepdub
2

Generate audio

from deepdub import DeepdubClient

client = DeepdubClient(api_key="dd-00000000000000000000000065c9cbfe")

audio = client.tts(
    text="Welcome to Deepdub! This is your first generated audio.",
    voice_prompt_id="50a537cf-1ec8-4714-b07e-c589ab76be4b",  # Promo / Commercials
    model="dd-etts-3.0",
    locale="en-US",
)

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

print(f"Generated {len(audio)} bytes of audio")

​
Generate speech with the JavaScript SDK

1

Install the SDK

npm install --save @deepdub/node
2

Generate audio

const { DeepdubClient } = require("@deepdub/node");

async function main() {
  const deepdub = new DeepdubClient("dd-00000000000000000000000065c9cbfe");
  await deepdub.connect();

  const buffer = await deepdub.generateToBuffer(
    "Welcome to Deepdub! This is your first generated audio.",
    {
      locale: "en-US",
      voicePromptId: "50a537cf-1ec8-4714-b07e-c589ab76be4b",  // Promo / Commercials
      model: "dd-etts-3.0",
    }
  );

  require("fs").writeFileSync("output.wav", buffer);
  console.log(`Generated ${buffer.length} bytes of audio`);
}

main();

​
Generate speech with cURL

curl -X POST https://restapi.deepdub.ai/api/v1/tts \
  -H "Content-Type: application/json" \
  -H "x-api-key: dd-00000000000000000000000065c9cbfe" \
  -d '{
    "model": "dd-etts-3.0",
    "targetText": "Welcome to Deepdub! This is your first generated audio.",
    "locale": "en-US",
    "voicePromptId": "50a537cf-1ec8-4714-b07e-c589ab76be4b"
  }' \
  --output output.mp3

​
Advanced generation options

Fine-tune your audio with accent blending and tuned parameters: 
audio = client.tts(
    text="This demonstrates accent blending with tuned parameters.",
    voice_prompt_id="bd1b00bb-be1c-4679-8eaa-0fcbfd4ff773",  # Storyteller
    model="dd-etts-3.0",
    locale="en-US",
    temperature=0.7,
    tempo=1.1,
    variance=0.6,
    sample_rate=44100,
    format="mp3",
    prompt_boost=True,
    accent_base_locale="en-US",
    accent_locale="fr-FR",
    accent_ratio=0.3,
)

with open("advanced_output.mp3", "wb") as f:
    f.write(audio)

​
Real-time streaming

For low-latency applications, stream audio chunks as they’re generated: 
import asyncio
from deepdub import DeepdubClient

client = DeepdubClient(api_key="dd-00000000000000000000000065c9cbfe")

async def stream():
    async with client.async_connect() as conn:
        audio = bytearray()
        async for chunk in conn.async_tts(
            text="Streaming audio in real time!",
            voice_prompt_id="50a537cf-1ec8-4714-b07e-c589ab76be4b",
            model="dd-etts-3.0",
            format="mp3",
        ):
            audio.extend(chunk)

        with open("streamed.mp3", "wb") as f:
            f.write(audio)

asyncio.run(stream())
