Realtime TTS 2.0 is a low-latency text-to-speech model with natural language steering, allowing you to control tone and emotion directly in the prompt (e.g., “[be happy and upbeat] Hello!”). It supports cross-lingual voices and multiple languages, enabling the same voice to speak consistently across different languages. This is an early access preview ahead of full launch, with ongoing improvements to voice quality and steering.

You can use cURL or any other http client to run inferences:

```bash
curl -X POST \
    -d '{"text": "The quick brown fox jumps over the lazy dog"}'  \
    -H "Authorization: bearer $DEEPINFRA_TOKEN"  \
    -H 'Content-Type: application/json'  \
    'https://api.deepinfra.com/v1/inference/inworld-ai/realtime-tts-2'
```

which will give you back something similar to:

```json
{
  "audio": null,
  "input_character_length": 0,
  "output_format": "",
  "words": [
    {
      "end": 1.0,
      "start": 0.0,
      "text": "Hello"
    },
    {
      "end": 5.0,

The DeepInfra OpenAI-compatible Speech API endpoint enables users to effortlessly convert text into speech audio. This document outlines how to integrate and utilize this endpoint to quickly create speech from text inputs, leveraging various audio output formats.

## Create speech

Use the following example of pythong code to generate an audio file from your text input:

```python
from pathlib import Path
from openai import OpenAI

client = OpenAI(base_url="https://api.deepinfra.com/v1/openai",
                api_key="$DEEPINFRA_TOKEN")

speech_file_path = Path(__file__).parent / "speech.mp3"
with client.audio.speech.with_streaming_response.create(
  model="inworld-ai/realtime-tts-2",
  voice="Ashley",
  input="The quick brown fox jumped over the lazy dog.",
  response_format="mp3",
) as response:
  response.stream_to_file(speech_file_path)
```

The API returns the generated audio file in the requested format (e.g., `mp3`, `pcm`). The example above saves the audio output directly as `speech.mp3`.

### Supported Audio Formats

| Format | Description                           | Recommended Usage                          |
|--------|---------------------------------------|--------------------------------------------|
| pcm    | Raw, uncompressed audio               | *Best for lowest latency streaming*        |
| mp3    | Compressed audio suitable for storage | General use and file distribution          |
| opus   | Compressed audio ideal for streaming  | Efficient streaming and real-time playback |
| flac   | Lossless audio compression            | High-quality archival storage              |
| wav    | Uncompressed audio                    | High-quality audio processing tasks        |

### Performance Recommendations

- **For lowest latency (fastest initial audio chunk):**
  - Use the `pcm` output format.

- **For general purposes:**
  - Use the `mp3` or `opus` formats for optimal balance between quality and file size.

Use the following example of js code to generate an audio file from your text input:

```javascript
import fs from "fs";
import path from "path";
import OpenAI from "openai";

const openai = new OpenAI(base_url="https://api.deepinfra.com/v1/openai",
                          api_key="$DEEPINFRA_TOKEN");

const speechFile = path.resolve("./speech.mp3");

async function main() {
  const mp3 = await openai.audio.speech.create({
    model: "inworld-ai/realtime-tts-2",
    voice: "Ashley",
    input: "The quick brown fox jumped over the lazy dog.",
    response_format: "mp3",
  });
  console.log(speechFile);
  const buffer = Buffer.from(await mp3.arrayBuffer());
  await fs.promises.writeFile(speechFile, buffer);
}
main();
```

The API returns the generated audio file in the requested format (e.g., `mp3`, `pcm`). The example above saves the audio output directly as `speech.mp3`.

### Supported Audio Formats

| Format | Description                           | Recommended Usage                          |
|--------|---------------------------------------|--------------------------------------------|
| pcm    | Raw, uncompressed audio               | *Best for lowest latency streaming*        |
| mp3    | Compressed audio suitable for storage | General use and file distribution          |
| opus   | Compressed audio ideal for streaming  | Efficient streaming and real-time playback |
| flac   | Lossless audio compression            | High-quality archival storage              |
| wav    | Uncompressed audio                    | High-quality audio processing tasks        |

### Performance Recommendations

- **For lowest latency (fastest initial audio chunk):**
  - Use the `pcm` output format.

- **For general purposes:**
  - Use the `mp3` or `opus` formats for optimal balance between quality and file size.



The DeepInfra OpenAI-compatible Speech API endpoint enables users to effortlessly convert text into speech audio. This document outlines how to integrate and utilize this endpoint to quickly create speech from text inputs, leveraging various audio output formats.

## Create speech

Use the following example `curl` request to generate an audio file from your text input:

```bash
curl https://api.deepinfra.com/v1/openai/audio/speech \
  -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "inworld-ai/realtime-tts-2",
    "input": "The quick brown fox jumped over the lazy dog.",
    "voice": "Ashley",
    "response_format": "mp3"
  }' \
  --output speech.mp3
```

The API returns the generated audio file in the requested format (e.g., `mp3`, `pcm`). The example above saves the audio output directly as `speech.mp3`.
