<!-- Start SDK Installation [installation] -->
## SDK Installation

The SDK can be installed with *uv*, *pip*, or *poetry* package managers.

### uv

*uv* is a fast Python package installer and resolver, designed as a drop-in replacement for pip and pip-tools. It's recommended for its speed and modern Python tooling capabilities.

```bash
uv add supertone
```

### PIP

*PIP* is the default package installer for Python, enabling easy installation and management of packages from PyPI via the command line.

```bash
pip install supertone
```

### Poetry

*Poetry* is a modern tool that simplifies dependency management and package publishing by using a single `pyproject.toml` file to handle project metadata and dependencies.

```bash
poetry add supertone
```

## SDK Example Usage

### Example

```python
# Synchronous Example
from supertone import Supertone, models


with Supertone(
    api_key="<YOUR_API_KEY_HERE>",
) as s_client:

    res = s_client.text_to_speech.create_speech(voice_id="<id>", text="<value>", language=models.APIConvertTextToSpeechUsingCharacterRequestLanguage.JA, model=models.APIConvertTextToSpeechUsingCharacterRequestModel.SONA_SPEECH_1, output_format=models.APIConvertTextToSpeechUsingCharacterRequestOutputFormat.WAV, include_phonemes=False)

    # Handle response
    print(res)
```

</br>

The same SDK client can also be used to make asynchronous requests by importing asyncio.
```python
# Asynchronous Example
import asyncio
from supertone import Supertone, models

async def main():

    async with Supertone(
        api_key="<YOUR_API_KEY_HERE>",
    ) as s_client:

        res = await s_client.text_to_speech.create_speech_async(voice_id="<id>", text="<value>", language=models.APIConvertTextToSpeechUsingCharacterRequestLanguage.JA, model=models.APIConvertTextToSpeechUsingCharacterRequestModel.SONA_SPEECH_1, output_format=models.APIConvertTextToSpeechUsingCharacterRequestOutputFormat.WAV, include_phonemes=False)

        # Handle response
        print(res)

asyncio.run(main())
```
<!-- End SDK Example Usage [usage] -->

<!-- Start Authentication [security] -->
## Authentication

### Per-Client Security Schemes

This SDK supports the following security scheme globally:

| Name      | Type   | Scheme  |
| --------- | ------ | ------- |
| `api_key` | apiKey | API key |

To authenticate with the API the `api_key` parameter must be set when initializing the SDK client instance. For example:
```python
from supertone import Supertone, models


with Supertone(
    api_key="<YOUR_API_KEY_HERE>",
) as s_client:

    res = s_client.text_to_speech.create_speech(voice_id="<id>", text="<value>", language=models.APIConvertTextToSpeechUsingCharacterRequestLanguage.JA, model=models.APIConvertTextToSpeechUsingCharacterRequestModel.SONA_SPEECH_1, output_format=models.APIConvertTextToSpeechUsingCharacterRequestOutputFormat.WAV, include_phonemes=False)

    # Handle response
    print(res)

```
<!-- End Authentication [security] -->

<!-- Start Models [models] -->

## Models

Supertone’s Text-to-Speech API provides multiple TTS models, each with different supported languages, available voice settings, and streaming capabilities.

### Model Overview

| Model Name         | Identifier        | Streaming Support (`stream_speech`) | Voice Settings Support                                   |
|--------------------|-------------------|--------------------------------------|----------------------------------------------------------|
| **SONA Speech 1**  | `sona_speech_1`   | ✅ Supported                         | Supports **all** Voice Settings                          |
| **Supertonic API 1** | `supertonic_api_1` | ❌ Not supported                  | Supports **only** the `speed` setting (others are ignored) |
| **SONA Speech 2**  | `sona_speech_2`   | ❌ Not supported                     | Supports **all** Voice Settings **except** `subharmonic_amplitude_control` |
| **SONA Speech 2 Flash**  | `sona_speech_2_flash`   | ❌ Not supported | Supports **all** Voice Settings **except** `similarity`, `text_guidance`,`subharmonic_amplitude_control` |


> [!NOTE]
> **Streaming Support**
>
> Streaming TTS using the `stream_speech` endpoint is **only available for the `sona_speech_1` model**.
>
> **Normalized Text Support**
>
> The `normalized_text` parameter is supported **only with the `sona_speech_2` and `sona_speech_2_flash` models**.  
> It is ignored when used with other models.

---

### Supported Languages by Model

> [!NOTE]
> The set of supported input languages varies depending on the TTS model.

- **sona_speech_1**
  - `en`, `ko`, `ja`

- **supertonic_api_1**
  - `en`, `ko`, `ja`, `es`, `pt`

- **sona_speech_2**
  - `en`, `ko`, `ja`, `bg`, `cs`, `da`, `el`, `es`, `et`, `fi`, `hu`, `it`, `nl`, `pl`, `pt`, `ro`,  
    `ar`, `de`, `fr`, `hi`, `id`, `ru`, `vi`
- **sona_speech_2_flash**
  - `en`, `ko`, `ja`, `bg`, `cs`, `da`, `el`, `es`, `et`, `fi`, `hu`, `it`, `nl`, `pl`, `pt`, `ro`,  
    `ar`, `de`, `fr`, `hi`, `id`, `ru`, `vi`

---

### Voice Settings (Optional)

Some TTS models support optional voice settings that allow fine control over output speech characteristics (e.g., speed, pitch, pitch variance).

> [!NOTE]
> The available Voice Settings vary depending on the TTS model.

- **sona_speech_1**
  - Supports **all** available Voice Settings.

- **supertonic_api_1**
  - Supports **only** the `speed` setting.
    All other settings will be ignored.

- **sona_speech_2**
  - Supports **all** Voice Settings **except** `subharmonic_amplitude_control`.

- **sona_speech_2_flash**
  - Supports **all** Voice Settings **except** `similarity`, `text_guidance`, `subharmonic_amplitude_control`.


> All Voice Settings are optional. When omitted, each model’s default values will be applied.

## Error Handling

[`SupertoneError`](./src/supertone/errors/supertoneerror.py) is the base class for all HTTP error responses. It has the following properties:

| Property           | Type             | Description                                                                             |
| ------------------ | ---------------- | --------------------------------------------------------------------------------------- |
| `err.message`      | `str`            | Error message                                                                           |
| `err.status_code`  | `int`            | HTTP response status code eg `404`                                                      |
| `err.headers`      | `httpx.Headers`  | HTTP response headers                                                                   |
| `err.body`         | `str`            | HTTP body. Can be empty string if no body is returned.                                  |
| `err.raw_response` | `httpx.Response` | Raw HTTP response                                                                       |
| `err.data`         |                  | Optional. Some errors may contain structured data. [See Error Classes](#error-classes). |

        # Handle response
        print(res)


    except errors.SupertoneError as e:
        # The base class for HTTP error responses
        print(e.message)
        print(e.status_code)
        print(e.body)
        print(e.headers)
        print(e.raw_response)

        # Depending on the method different errors may be thrown
        if isinstance(e, errors.BadRequestErrorResponse):
            print(e.data.status)  # str
            print(e.data.message)  # str
