# Unreal Speech API de conversão de texto em fala com geração rápida, timestamps e vozes Kokoro TTS - Findings24: - Site: - Preços: Freemium - Categorias: Gerador de voz com IA ## O que é Unreal Speech? Unreal Speech is a text-to-speech API built for developers who need to convert written text into spoken audio with low latency and flexible output options. The site positions it as a production-ready service with streaming synthesis, timestamp support, and a browser-based demo for quick testing. The product site shows several ways to use the platform: a fast `/stream` endpoint, a `/speech` endpoint that can return MP3 and timestamp URLs, an asynchronous `/synthesisTasks` flow for longer text, and a WebSocket endpoint for streaming audio together with word-level timestamps. The studio page adds a free online demo built on Kokoro TTS, with 48 voices across 8 languages for browser-based generation and download. ## O que Unreal Speech pode fazer? ### Fast streaming synthesis The homepage and docs show a fast streaming path for text-to-speech output, with audio available in about 300ms for the \`/stream\` endpoint. ### Multiple API workflows The API supports multiple output patterns: synchronous, asynchronous, and WebSocket-based streaming, so teams can choose the workflow that fits text length and latency needs. ### Timestamp generation The site documents word- or sentence-level timestamps, including a \`/streamWithTimestamps\` WebSocket flow for real-time timing data. ### Voice and language selection The studio demo presents 48 voices across 8 languages, giving users a broad set of voice and language options to test. ### Long-form and scaled usage The pricing page says the service can generate up to 10-hour audio and offers plans that scale by character volume, including a free tier and higher-volume paid plans. ### Live browser demo The browser studio lets visitors type text, generate speech, and download recordings directly in the browser for quick evaluation. ## Casos de uso ### Fast interactive playback Use the low-latency \`/stream\` endpoint when you want spoken output to start quickly, such as interactive app responses or realtime narration previews. ### Batch audio generation Use \`/speech\` or \`/synthesisTasks\` when you need generated audio files for shorter clips or longer passages, including longer-form content that exceeds the synchronous path. ### Timed text highlighting Use word- or sentence-level timestamps when your app needs highlighting, caption sync, or narration playback that stays aligned with text. ### Voice evaluation and prototyping Use the studio demo to test voices in the browser, compare language options, and download sample recordings before integrating the API. ### Scaling usage over time Use the pricing tiers to match character volume to usage patterns, starting with the free tier and moving to higher-volume plans as demand grows. ## Perguntas frequentes ### Does Unreal Speech offer a free way to try the product? Yes. The pricing page lists a free tier and paid plans, and the site also offers a live studio demo for testing text-to-speech generation in the browser. ### What API workflows does it support? The docs shown on the homepage include \`/stream\`, \`/speech\`, \`/synthesisTasks\`, and \`/streamWithTimestamps\`. The site says \`/stream\` is synchronous and fast, \`/speech\` returns MP3 plus timestamp URLs, \`/synthesisTasks\` is asynchronous for longer text, and \`/streamWithTimestamps\` streams audio with word-level timing. ### Can it generate timestamps with the audio? The site says timestamps can be requested with \`TimestampType\` set to \`word\` or \`sentence\`, and it also mentions a WebSocket flow for streaming both audio and timestamps. ### How many voices and languages are available? The studio page says Kokoro TTS Studio supports 48 voices across 8 languages, including American and British English, French, Hindi, Spanish, Japanese, Chinese, Italian, and Portuguese. ### Is the browser demo the same as the API product? The site positions Unreal Speech for commercial use through its API documentation, while the studio page describes the browser demo as a free online text-to-speech experience for trying the model and downloading audio. ## Informações rápidas - **Category**: Text-to-speech API - **Source domain**: unrealspeech.com - **Primary users**: Developers - **Demo**: Browser-based studio for Kokoro TTS - **Voices and languages**: 48 voices across 8 languages - **Pricing**: Free tier plus paid plans
