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.
SpeechGen

What is SpeechGen?
SpeechGen.io is an online text-to-speech studio with more than 5,000 neural voices across 150 languages. Paste or upload text, pick a voice, tune speed, pitch, volume, and SSML tags, then export MP3, WAV, or FLAC files without a monthly subscription.
The editor supports long-form jobs, subtitle-to-audio conversion, document imports, and a voice cloning flow that builds a custom voice from a short audio sample. SpeechGen also runs audio-to-text transcription for uploaded files, videos, and YouTube links with SRT and VTT export.
New accounts receive free credits to test synthesis, and additional usage is sold as one-time credit packs through card or PayPal checkout. An API is available for developers who want to automate generation inside their own workflows.
