Voice Settings
ElevenLabs provides users with a range of customization options through its Voice Settings tab. These settings allow for fine-tuning the generated voice to achieve the desired output. The main adjustable parameters include:
-
Voice Stability: This slider determines the consistency and emotional range of the voice. Lower stability values result in more expressive and varied speech, while higher values produce more stable and monotonous output. Users should experiment with this setting to find the right balance for their project.
-
Clarity + Similarity Enhancement: Primarily used with the Voice Changer tool, this setting affects the clarity of the generated speech. Lower values are recommended when dealing with distortions, while higher values can improve overall clarity. However, extremely high values may introduce new distortions, so it's best to maintain a balanced approach.
-
Style Exaggeration: Another setting mainly utilized with the Voice Changer tool, style exaggeration is set to 0.0 by default for optimal generation speeds. Increasing this value can produce more exaggerated speech compared to the input audio, but very high values may lead to instability.
-
Speaker Boost: This option enhances the similarity between the generated speech and the original voice. While enabling it may slightly reduce generation speeds, the differences are generally subtle. Users can keep this setting enabled by default for improved voice matching.
Creating Custom Voices
ElevenLabs offers voice cloning capabilities, allowing users to create custom voices based on their own recordings or other audio samples. This feature is particularly useful for those involved in e-learning narration or managing faceless YouTube channels.
To create a custom voice, users need a high-quality audio or video recording of the desired voice, ranging from 1 to 5 minutes in length and under 10 megabytes in size. The platform's instant voice cloning feature, available to paid subscribers, can quickly generate a clone of the uploaded voice sample.
Once the custom voice is created, users can fine-tune it using the voice settings mentioned earlier. This process allows for adjusting the stability and clarity to achieve a more realistic and natural-sounding output. For example, setting the stability to around 35 and the clarity/similarity enhancement to 54 can help reduce the robotic quality of the cloned voice and produce a more lifelike result.
By combining the extensive pre-made voice library with powerful customization options and voice cloning capabilities, ElevenLabs provides users with the tools to find or create the perfect voice for their projects, regardless of the language or style required.

Voice Cloning and Changing
ElevenLabs offers advanced voice cloning and changing capabilities, allowing users to create realistic AI-generated voices for various applications. These features have gained popularity among content creators, gamers, and professionals seeking to produce diverse voices and audio effects.
Instant Voice Cloning
ElevenLabs' Instant Voice Cloning (IVC) feature enables users to quickly create a digital likeness of a voice based on short samples. This service is available to paid subscribers at a competitive rate, starting from as low as USD 1.00. To use IVC, users need a high-quality audio or video recording of the desired voice, ranging from 1 to 5 minutes in length and under 10 megabytes in size.
The process of instant voice cloning is remarkably fast, taking only seconds to generate a clone voice and add it to the user's voice lab. While the results may not be an exact match, they often come close to replicating the original voice. Users can then fine-tune the cloned voice using various settings to achieve a more realistic output.
Professional Voice Cloning
For those requiring higher accuracy and quality, ElevenLabs offers Professional Voice Cloning (PVC). This feature allows users to train a hyper-realistic model of a voice by using a large set of voice data. The result is a model that's nearly indistinguishable from the original voice.
PVC requires more time to train compared to IVC, with current estimates ranging from about 3 hours for English to 6 hours for multilingual clones. To achieve optimal results, users should follow these guidelines:
- Provide at least 30 minutes of audio, with 3 hours being ideal for the most accurate clone.
- Ensure there's only a single speaking voice throughout the audio samples.
- Use samples that match the intended speaking style and language of the final output.
- Submit high-quality audio free from artifacts and unwanted noise.
Voice Changing Tool
ElevenLabs' AI voice changer is a sophisticated tool that allows users to transform their voice into another with full control over delivery. This technology employs advanced algorithms to modify voice properties, enabling changes ranging from subtle adjustments in tone to dramatic transformations.
