These models use deep learning techniques, such as neural vocoders and transformer-based architectures, to generate human-like speech with variations in tone, pitch, and emphasis. Many modern TTS systems support multiple languages, voices, and even emotional expressions for more engaging and realistic audio output. Advanced TTS models offer features like speaker adaptation, voice cloning, and fine-tuned prosody control, allowing for highly customizable speech synthesis. Some solutions run on-device for real-time applications, while cloud-based TTS services provide scalable, high-quality synthesis for larger workloads. Developers can integrate TTS into their applications through APIs, enabling dynamic voice generation for customer support, content creation, and assistive technologies. ## All Available Text-to-Speech Models

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.aimlapi.com/api-references/speech-models/text-to-speech.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
