ElevenLabs: AI-Powered Speech Synthesis Tool

ElevenLabs is an innovative AI-powered speech synthesis tool that allows users to generate voiceovers using their own voices. With a wide range of features and models, ElevenLabs provides users with the ability to create high-quality and natural-sounding audio for various applications.

The platform provides an extensive documentation section that guides users through the different aspects of speech synthesis, including an API reference, Python library, and community support. Whether you are a beginner or an experienced user, ElevenLabs has resources to support your needs.

Speech Synthesis Models

ElevenLabs offers several AI models for speech synthesis, each with its own strengths and areas of expertise. The available models as of September 2023 are:

  • Multilingual v2: This model supports 28 languages, providing stability, language diversity, and accurate voice cloning. While it may take slightly longer to generate audio, it delivers exceptional results. It is recommended to use high-quality voice samples for optimal performance.
  • Turbo v2: The Turbo v2 model is optimized for low-latency applications without compromising vocal performance. Although it is an English-only model, it offers excellent accuracy and stability. Users can expect consistent latency of around 400ms.
  • English v1: As the first model developed by ElevenLabs, English v1 serves as the foundation for the subsequent models. It is trained solely on English datasets and is known for its reliability and speed. However, it may have limitations in accuracy and flexibility compared to newer models.
  • Multilingual v1: This experimental model is still in its early stages and may have some bugs and refinements to address. It is recommended to keep text chunks below 800 characters for optimal results. However, the Multilingual v2 model has surpassed Multilingual v1 in almost every aspect, offering better performance and stability.

Each model caters to specific requirements and languages, allowing users to choose the most suitable option for their projects.

Voice Settings

ElevenLabs provides users with voice settings that allow customization and control over the generated audio output. The stability and similarity sliders play a crucial role in tailoring voice performances:

  • Stability: Setting the stability slider determines the range of randomization between each generation. Lower stability values result in a wider range of emotions and a more emotive performance. However, the impact of stability on the voice largely depends on the original voice itself.
  • Similarity: The similarity slider controls the similarity between each generation. Higher similarity values tend to provide more consistent audio outputs. It is recommended to experiment with different values to achieve the desired tone and performance.

While the AI is non-deterministic, setting specific values for the sliders does not guarantee the same results every time. Instead, the sliders function as a range, allowing users to strike a balance between emotive and consistent audio outputs.

Hovering over the information icon next to the sliders provides additional details on their functionality.

Best Practices and Recommendations

Based on user feedback and experience, ElevenLabs offers some best practices and recommendations for optimal results:

  • Use high-quality voice samples with the desired performance, accent, and tone for accurate cloning.
  • For multilingual projects, consider using voices that were originally cloned from speakers of the target language to ensure proper pronunciation and accent.
  • When using the multilingual model, keep text chunks below 800 characters to minimize potential issues.
  • Experiment with different voice settings to find the best combination for your specific project and desired performance.
  • Take advantage of the extensive documentation and community support offered by ElevenLabs to enhance your understanding and proficiency.

By following these best practices and recommendations, users can maximize the potential of ElevenLabs and create high-quality voiceovers that meet their requirements.


ElevenLabs is a cutting-edge AI-powered speech synthesis tool that empowers usersto generate professional voiceovers using their own voices. With a range of models and customizable voice settings, users can achieve accurate and natural-sounding audio outputs for various applications.
