AudioDoc
What is AudioDoc?
AudioDoc turns documents and pasted text into listenable audio in your browser. Upload a PDF, EPUB, or markdown file, or drop raw text into the TTS studio, and hear it read by natural narrators. There is no account requirement, no subscription, and no credit card gate to start.
The document library streams long files chapter by chapter as audio is generated, so you are not waiting on a full book conversion before playback begins. A separate TTS studio handles quick paste-and-listen jobs with downloadable clips and no watermarks.
It fits commuters who want articles read aloud, students reviewing coursework, writers proofreading drafts by ear, and anyone who needs hands-free or accessibility-friendly access to written material. Guest sessions last 24 hours; a free registered account keeps your library and listening progress beyond that window.
Unreal Speech
What is Unreal Speech?
Unreal Speech is a production-ready text-to-speech API built on the open-source Kokoro TTS engine. It gives developers and businesses natural speech synthesis at a fraction of the cost of ElevenLabs, Amazon Polly, Google Cloud, and Microsoft Azure. The API streams audio in about 300 milliseconds and supports long-form jobs up to 10 hours per request.
Kokoro runs on an 82-million-parameter decoder-only model that blends ideas from StyleTTS 2 and iSTFTNet. You get 48 voices across eight languages, including US and UK English, Mandarin, Hindi, Spanish, Portuguese, Japanese, French, and Italian. Per-word timestamps let apps highlight text in sync with playback, which helps with accessibility, karaoke-style UIs, and interactive readers.
The REST API exposes four endpoints: /stream for sub-second synthesis of up to 1,000 characters, /speech for up to 3,000 characters with timestamp URLs, /synthesisTasks for async jobs up to 500,000 characters, and a websocket /streamWithTimestamps route for live audio plus word timing. SDKs ship for Python, Node.js, and React Native, with sample code on the homepage.
Kokoro TTS Studio on unrealspeech.com offers a free browser demo to test voices before signing up. Paid plans remove attribution requirements for commercial audio. Enterprise customers on the platform process billions of characters monthly with 99.9% uptime.
