Introduction

Our Text-to-Speech technology, also known as Speech Synthesis, is the core of ElevenLabs. It serves as the foundation for many of the features we offer and powers many services worldwide. This technology transforms text into incredibly realistic speech.

To ensure you get the most out of this feature, it is important to use an appropriate voice for what you are trying to achieve and to familiarize yourself with the different models we offer, as both of these factors have a tremendous effect on the delivery and quality of the output.

Our Speech-to-Speech technology, also known as Voice Changer, converts a source voice (audio input) into a different voice while retaining the source voice’s accent, cadence, and overall delivery, but with the timbre and vocal quality of the selected voice.

This feature is great for standalone usage, as it provides your voice acting with a wider range of tonalities. Additionally, when used in conjunction with Text-to-Speech, it allows for easy correction of pronunciations and adds specific performances or characteristics, emulating subtle vocal nuances for a more human touch. You can make the AI whisper, sigh, laugh, or cry by simply acting it out and then using the voice changer.

Our Sound Effects generator allows you to create a wide range of audio effects by inputting descriptive prompts. This feature is great across variety of uses, such as film sound design, video game audio, music production, and much more. Users can generate sounds by typing a description into a text box, and the AI will produce multiple variations based on the given prompt.

The tool offers settings to control the duration of the sound and how closely the output adheres to the prompt.

Voice Design allows for the creation of unique voices from text prompts, filling gaps when specific voices aren’t available in the Voice Library or where you might even prefer a synthetically generated voice. You can create both realistic voices, which focus on attributes like age, accent, and emotion, and character voices, which allow you to create more creative voices by using more creative language.

Instant Voice Cloning enables you to create voice clones quickly from short audio samples, without the need for training. It uses a technology to create voice instantaneously, capturing its tone and inflections. While effective for many voices, it may struggle with unique accents or voices not encountered during training. High-quality, consistent audio samples are crucial for optimal results.

Professional Voice Cloning creates hyper-realistic voice models by training on larger datasets of a speaker’s voice. Available from the Creator tier and above, it offers extremely higher accuracy and can capture intricate details, such as accents and tonal nuances. This method requires more audio data, between 1 - 3 hours, and a few hours to train the model but results in a voice clone that closely resembles the original.

The Voice Library is a marketplace where users can share and discover a wide variety of voices, including professional voice clones from real people who have cloned their voices and decided to share them with the rest of the community.

It offers filters and search options to help users find specific voice styles, languages, and accents. Users can add voices to “My Voices” for use across ElevenLabs features, and shared voices can earn either credits or monetary rewards based on usage.

Projects is a comprehensive tool for creating long-form audio content, such as audiobooks. It allows users to upload documents or web pages and generate voiceover narrations. It is easy to manage and keep track of all of your projects, select voices, and adjust settings for quality and download options. Projects is available on paid tiers, offering an efficient workflow for producing lengthy audio content.

Dubbing allows you to create high-quality dubs in various languages while preserving the original performance. You can upload or import video/audio files and select the original and target languages. The tool supports multiple formats and offers options for modifying specific parts of the dub. It’s available on all plans, with advanced features in the Dubbing Studio.

Voiceover Studio allows you to create interactive audio content with flexibility. It combines an audio timeline with text-to-speech, speech-to-speech, and sound effects, enabling the creation of dialogues between multiple speakers. You can upload videos or start projects from scratch, adding voiceover and sound effects tracks. Available on the Creator plan and above, it offers tools for crafting detailed and dynamic voiceover projects.

Audio Native is an embedded audio player that automatically voices web page content using ElevenLabs’ text-to-speech service. It allows embedding pre-generated audio from projects into web pages with a simple HTML snippet. Available on the Creator plan and above, it includes metrics for tracking audience engagement through a listener dashboard.

Conversational AI is a platform for deploying interactive voice agents that can interact with you or your users in natural conversations. It integrates Speech to Text, Language Models, and Text to Speech, along with features like interruption handling and turn-taking logic. Users can customize agents with different voices and system prompts, making it suitable for applications like customer service, virtual assistants, and interactive characters.
