## Getting Started with ElevenLabs API

To begin using the ElevenLabs API, first
[create an ElevenLabs account](https://elevenlabs.io/developers) and obtain your
API key from your profile settings. This key (xi-api-key) serves as your
authentication token for all API requests.

You have several integration options:

- Direct REST API calls
- Official Python SDK
- Community-supported libraries for other languages

Python users can install the package with:

```bash
pip install elevenlabs
```

For other languages, any library capable of making HTTP requests will work. To
ensure seamless integration and a great developer experience, you might find
these
[developer experience tips](/learning-center/rickdiculous-dev-experience-for-apis)
helpful.

Here's a basic text-to-speech example using Python:

```python
from elevenlabs import generate, play

audio = generate(
    text="Hello world! This is my first ElevenLabs API request.",
    voice="Rachel",
    model="eleven_monolingual_v1"
)

play(audio)
```

For real-time audio streaming:

```python
from elevenlabs import generate, stream

audio_stream = generate(
    text="This is a streaming example of the ElevenLabs API.",
    voice="Rachel",
    model="eleven_monolingual_v1",
    stream=True
)

stream(audio_stream)
```

To save audio to a file:

```python
audio = generate(
    text="Let's save this audio to a file.",
    voice="Rachel"
)

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

Always include error handling for production applications:

```python
from elevenlabs import generate
from elevenlabs.api import Error as ElevenLabsError

try:
    audio = generate(
        text="This might raise an error if something goes wrong.",
        voice="Rachel"
    )
except ElevenLabsError as e:
    print(f"An error occurred: {str(e)}")
```

## ElevenLabs API: Advanced Features and Customizations

The ElevenLabs API provides precise control over voice characteristics:

- **Pronunciation**: Fix tricky words using IPA or CMU notation
- **Speaking Speed**: Set rates between 0.7x and 1.2x
- **Stability & Similarity**: Control voice consistency and resemblance
- **Style and Emotion**: Adjust expressiveness from deadpan to dramatic

Here's how to customize voice settings:

```python
audio = client.generate(
    text="Welcome to our platform!",
    voice=Voice(
        voice_id='your_voice_id',
        settings=VoiceSettings(
            stability=0.85,
            similarity_boost=0.7,
            style=0.3,
            use_speaker_boost=True
        )
    )
)
```

### Using SSML for Enhanced Output

Speech Synthesis Markup Language (SSML) provides granular control over speech
output:

SSML Tag Function Example Effect `<break>` Insert a pause or silence Adds a
pause for natural phrasing `<prosody>`Adjust pitch, rate, volume Makes speech
sound faster, slower, etc. `<emphasis>` Emphasize a specific word/phrase
Increases word clarity or dramatic impact `<phoneme>` Specify phonetic
pronunciation Ensures technical terms are said correctly

Wrap your text with `<speak>` tags to use SSML.

For standardizing your API interfaces, consider using tools like
[TypeSpec for APIs](/learning-center/bringing-types-to-apis-with-typespec).

### Optimizing Performance

1. **Voice Selection**: Choose voices that naturally fit your language and tone
2. **Model Choice**: Select "Turbo v2" for advanced features, "Multilingual v2"
   for language variety, or "Flash v2.5" for speed
3. **Real-Time Streaming**: Stream audio as it generates for responsive
   applications

```python
def text_stream():
    yield "Hi! I'm Brian "
    yield "I'm an artificial voice made by ElevenLabs "
audio_stream = client.generate(
    text=text_stream(),
    voice="Brian",
    model="eleven_monolingual_v1",
    stream=True
)
stream(audio_stream)
```
