ElevenLabs offers a comprehensive guide to creating professional-grade voice clones using their Text to Speech technology, emphasizing the importance of high-quality input data and precise prompts for optimal results. The process involves starting with pristine recordings in quiet environments using suitable equipment, capturing expressive and varied speech, and ensuring a clean dataset devoid of flaws such as filler words and inconsistent recording conditions. The guide highlights the significance of maintaining consistency in recording conditions, providing the right amount of training data tailored to the intended use case, and fine-tuning settings for stability and similarity. It also suggests stress-testing voice clones in real scenarios to evaluate their performance across different contexts and advises on managing voice clone libraries effectively through naming conventions, version control, and metadata documentation. ElevenLabs encourages users to experiment and iterate, offering both a free tier and upgrade options for additional features like voice mixing and multilingual cloning.
